List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Tue, 03 Jul 2012 12:36:40 -0000 Hi Authors, I have few queries regarding ESADI protocol as per draft-ietf-trill-esadi-00, base RFC 6325 and RFC 6165. 1>In base RFC 6325 Section 4.2.4.4 (5.4) "In addition, the LSP contains the following information on a per- VLAN basis: 5.4. Per-VLAN ESADI protocol participation flag, priority, and holding time. If this flag is one, it indicates that the RBridge wishes to receive such TRILL ESADI frames" The per vlan ESADI protocol participation flag is send via "Interested VLANs and Spanning Tree Roots Sub-TLV" in TRILL LSP.The per vlan ESADI priority is send via "ESADI Parameter APPsub-TLV" in ESADI LSP 0. Is the "holding time" same as "CSNP time" field in "ESADI Parameter APPsub-TLV"? 2>The Inner.VLAN tag for ESADI LSP indicates the VLAN to which the ESADI-LSP applies, the vlan in MAC-Reachability TLV is unused.Why do not we use the MAC-Reachability TLV's vlan field ? If we use MAC-Reachability TLV's vlan field we can merge multiple ESADI-LSPs to one ESADI LSP and reduce number of ESADI LSPs. Currently if we have 4k VLANs enabled on an ESADI RBridge it has to send 4k ESADI LSPs. This can be reduced using the MAC-Reachability TLV's vlan field. 3> What should be the deciding factor behind unicast-ing a ESADI LSP and sending it on a DTree? Should it be the number of ESADI RBridges in the campus? 4> If DTrees are already pruned, it would be good to send ESADI LSPs on vlan pruned Dtree. Can we further prune these vlan pruned DTrees based on the RBridges participating in ESADI for a particular vlan.

That's only true if the ESADI RBridge is participating in ESADI for all of those VLANs. And there are two reasons (1) draft-ietf-trill-rbridge-vlan-mapping, and (2) if there were information in an ESADI-LSP PDU for say, two different VLANs, only one of these could appear at the VLAN ID in the Inner.VLAN so there is no way to guarantee that the PDU would get to RBridges participating in ESADI only for the other VLAN due to distribution tree pruning (see your question 4 below). > 3> What should be the deciding factor behind unicast-ing a ESADI LSP > and sending it on a DTree? Should it be the number of ESADI RBridges > in the campus? The text related to this aspect of the current ESADI draft could probably do with review and clarification. Obviously, all the destination ESADI RBridges have to indicate that they support unicast receipt. I would say that, to a first approximation, it is best to use unicast if their is one intended recipient and a distribution tree if there are multiple recipients. There being only one intended recipient for a particular ESADI-LSP does not imply that there are only two ESADI RBridges for that VLAN. > 4> If DTrees are already pruned, it would be good to send ESADI LSPs > on vlan pruned Dtree. Can we further prune these vlan pruned DTrees > based on the RBridges participating in ESADI for a particular clan. Since ESADI--LSP PDUs are treated by transit RBridges like any other multi-destination TRILL Data packet, they will automatically use any distribution tree VLAN pruning available. Further pruning those trees based on ESADI participation is an obvious improvement that will work fine whether it is implemented for all or some of the RBridges in a campus. But this wasn't included in the TRILL specifications because it did not, at the time, seem worth the additional complexity. It seemed like that in a well configured network, either none of the RBridges interested in a particular VLAN would be ESADI participants for that VLAN or all or almost all of them would be. Pruning on ESADI participation does no good in the none or all cases and probably helps most somewhere in the middle. Thanks, Donald ============================= Donald E.

The requirements doc says that the solution needs to be able to discover the various components of an ecmp for traceroute, loopback/ping etc. However, 802.1ag was developed for an environment that wasn't ecmp capable, so the frame format doesn't lend itself naturally for performing ecmp discovery. In particular, consider this: a) The proposed method for OAM packet identification, which for IP is by matching on a src IP (plus rbridge in the case of unicast IP), will make the OAM packet take a different route than that taken by the flow you're trying to debug. Note that this was not an issue for an 802.1ag based CE environment because as long as you get the vlan right, data packets and OAM packets will follow the same (only available) path. b) Further in the doc, (section 5:Loopback Message) seems to imply that the selection of the ecmp path would be signalled from the ingress somehow. Let's say that your network looks like this: A-B-C-D, where B is connected to C by 3 paths and C is connected to D, also by 3 paths. Let's say you want to send a loopback message from A to D. How does A signal that B needs to pick the "first link in the ecmp" and C needs to pick the "third link"? The writeup seems to imply this information is somehow embedded in the loopback OAM TLVs.

This document is the framework for directory assisted edge. Besides that technique and ESADI, there is also multi-destination frame reduction material in draft-perlman-trill-rbridge-multilevel-04.txt Section 4.2. If someone wants to do a draft talking about the general problems of broadcast domain scaling, multi-destination frames, and the like, that would be fine, but that doesn't seem like this draft. > 2.

I don't see how much clarification could be done without an undersireable amount of patent discussion. Anyone who wants to can go look at the disclosure and the international patent application and its initial rejection by the selected international search agency, all of which are, I believe, a matter of public record. Some people tell me that filing a disclosure against a framework document just "isn't done" and you should only file against more technical documents. I have looked at RFC 3979 and don't see any basis forthat. If you have IPR that covers any part of the ideas in a draft, even if it is a framework draft, it looks to me like your are required to file. As the sole inventor and personal owner of the cited international patent application and a co-author of the draft and a holder of the office of WG Co-Chair, it seems to me that I should be particularly careful to file disclosures, even in cases were where it may not be so clear I am required to.

The authors should make it more clear in the draft that this is the problem statement and the framework.

This draft is a work item of the Transparent Interconnection of Lots of Li= nks Working Group of the IETF. Title : TRILL Edge Directory Assistance Framework Author(s) : Linda Dunbar Donald Eastlake Intel Labs Igor Gashinsky Filename : draft-ietf-trill-directory-framework-00.txt Pages : 14 Date : 2012-07-09 Abstract: Edge RBridges currently learn the mapping between MAC addresses and their egress RBridges by observing the data packets traversed through. When ingress RBridge receives a data frame with its destination address (MAC&VLAN) unknown, the data frame is flooded across the TRILL campus. When there are more than one RBridge ports connected to one bridged LAN, only one of them can be designated as AF port for forwarding/receiving traffic for each LAN, the rest have to be blocked for that LAN. This draft describes the framework for using directory service to assist edge RBridges to improve TRILL network scalability in data center environment.

Donald,

 

The Figure 2  in RFC 6325 shows that “TRI= LL Header” and “Inner Ethernet Header” are two separate f= ields. The Figure 5 of RFC6325 continues the view with “TRILL Header&= #8221;  only including the fields of:

 

But on page 5 of  “draft-ietf-fine-labeli= ng-01”, the TRILL frame figure implies that TRILL Header includes the= “Inner.MacDA” and “Inner.MacSA”.

 

 

 

does the “Native Payload” in this figure= include “Inner MAC-DA” and “inner MAC-SA”?

 

Thanks,

FGL can only appear inside. Since RBridges are currently specified as customer devices, if an RBridge sends a frame on an Ethernet link and the RBridge port is configured to send tagged frames, the frame will have an outer C-VLAN tag. However, as it says here and there, use of S-VLAN tags is an obvious extension. > - Section 5.1: Can FGL RBridge also do VL RBridge function?

Yes, I believe the draft requires an FGL RBridge to be able to do VL. Section 5.1 says that a port may be configured to do FGL ingress process implying that by default it does VL ingress processing that Section 5.1 says in unchanged. > - Same goes with Section 5.3: when X is VL specifiable only, why > can=92t the FGL RBridge simply decapsulates the frame as regular VL RBrid= ge? I believe it can and must. The wording in Section 5.3 is less clear than 5.1 and should probably state this more explicitly.

The Figure 2 =A0in RFC 6325 shows that =93TRILL Head= er=94 and =93Inner Ethernet Header=94 are two separate fields. The Figure 5= of RFC6325 continues the view with =93TRILL Header=94=A0 only including th= e fields of:

But on page 5 of =A0=93draft-ietf-fine-labeling-01= =94, the TRILL frame figure implies that TRILL Header includes the =93Inner= .MacDA=94 and =93Inner.MacSA=94.

does the =93Native Payload=94 in this figure include= =93Inner MAC-DA=94 and =93inner MAC-SA=94?


No.

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 12 Jul 2012 12:31:45 -0000 Hi Authors, I have few comments and a query about draft-ietf-trill-esadi-00. 1> Section 4.2 Receipt of ESADI PDUs "Because all ESADI instance for VLAN-x are adjacent, when RB1 receives an ESADI-CSNP from RB2 and detects that it has ESADI-LSPs that RB1 is missing, it sets the transmission flag only for its own ESADI-LSPs that RB1 is missing. Missing ESADI-LSPs originated by other ESADI instances will be detected by those other instances." I am not able to understand the quoted sentences.Could you please clarify? 2> The figure 2 and 3 in Section 2. ESADI Protocol Overview have the Inner MAC DA as "Next Hop Dest. Address" which should be "All-Egress-RBridges" (formerly called "All-ESADI-RBridges") 3> In Section 6. ESADI-LSP Contents "ESADI-LSP number zero MUST NOT exceed 1470 minus 24 bytes in length (1446 bytes) but if received longer, it is still processed normally." should be changed to "The ESADI payload for ESADI-LSP number zero MUST NOT exceed 1470 minus 24 bytes in length (1446 bytes) but if received longer, it is still processed normally." Also should it be 1470-24 or Sz-24 ? Sz being the campus wide MTU.

List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 12 Jul 2012 15:26:20 -0000 A few comments: It seems to me that the top level difficulty with this draft is that it assumes that TRILL is an Ethernet protocol. But it isn't. Where do these tags go in the TRILL Data frame on a PPP link [RFC6361] or in the possible IPv4/6 link format in draft-mrw-trill-over-ip or in the possible MPLS TRILL Data format in draft-ietf-l2vpn-trill-evpn? You could put new tags after the Inner.VLAN or you could expand the TRILL Header but trying to put new tags in front of the TRILL Header seems problematic and also guarantees that only new hardware can process the frame at all. Ignoring the above problem and commenting on the multi-topology and nickname expansion aspects of the draft: I'm not sure why the topology ID tag has 16 bits of topology when all the other IS-IS related topology things I know about have 12 bits of topology ID and, in the real world, I understand it is very rare to use more than around 8 topologies. Also, the interesting alternative of encoding the topology in the Outer.VLAN tag, which only works on Ethernet links, would tend to use the 12-bit VLAN ID for topology although I suppose, depending on how big a change you are making in the port silicon, you could repurpose the priority and DEI bits... Anyway, having a few reserved flag bits sometimes turns out to be extremely useful so I'm thinking that sticking with 12 bits would be better. And, in any case, redefining the content of the VLAN tag while continuing to use the C-VLAN Ethertype would be viewed as a problem by some. I'm not sure why there has to be an MT Capability bit. Wouldn't just not including the MT TLV be a good enough indication if you required even an MT capable RBridge only participating in base topology zero to include the MT TLV? If you are going to expand the nickname space, I don't quite see why you only add 8 bits and why, it appears, you are going for a larger flat nickname space. There is power in hierarchy. Perhaps you mean for the 8 bits to be used somewhat hierarchically for naming areas in multi-level or the like but it doesn't sound like that. Going to a flat 24-bit nickname seems like it, in general, requires new silicon and biases the design towards high end switches with bigger tables, etc. If you need new silicon anyway, I think that adding 16-bits with a fixed hierarchy split of the upper and lower 16-bit parts and using something like the "swap nickname" logic suggest in draft-perlman-trill-rbridge-mulilevel-04.txt would enable forwarding tables to remain small and better support a wider range of switches.

But it isn't. Where do these tags = go in the TRILL Data frame on a PPP link [RFC6361] or in the possible IPv4/= 6 link format in draft-mrw-trill-over-ip or in the possible MPLS TRILL Data= format in draft-ietf-l2vpn-trill-evpn? You could put new tags after the In= ner.VLAN or you could expand the TRILL Header but trying to put new tags in= front of the TRILL Header seems problematic and also guarantees that only = new hardware can process the frame at all. [Answer] These are encoded hop-by-hop. Superior RBridge do not include when= interfacing with older RBridges. Ignoring the above problem and commenting on the multi-topology and nicknam= e expansion aspects of the draft: I'm not sure why the topology ID tag has 16 bits of topology when all the o= ther IS-IS related topology things I know about have 12 bits of topology ID= and, in the real world, I understand it is very rare to use more than arou= nd 8 topologies. Also, the interesting alternative of encoding the topology= in the Outer.VLAN tag, which only works on Ethernet links, would tend to u= se the 12-bit VLAN ID for topology although I suppose, depending on how big= a change you are making in the port silicon, you could repurpose the prior= ity and DEI bits... Anyway, having a few reserved flag bits sometimes turns out to be extremely= useful so I'm thinking that sticking with 12 bits would be better. And, in= any case, redefining the content of the VLAN tag while continuing to use t= he C-VLAN Ethertype would be viewed as a problem by some. [Answer] Point taken. It was made 16 bit aligned. But next rev we can carve= out the upper 4-bits as reserved bits. I'm not sure why there has to be an MT Capability bit. Wouldn't just not in= cluding the MT TLV be a good enough indication if you required even an MT c= apable RBridge only participating in base topology zero to include the MT T= LV? [Answer] MT capability bit was added to identify the MT capability in the H= ello message itself. However, we can discuss the use of the MT TLV for the = purpose. I did not quite understand the inclusion of MT TLV in base topolog= y question. If you are going to expand the nickname space, I don't quite see why you on= ly add 8 bits and why, it appears, you are going for a larger flat nickname= space. There is power in hierarchy. Perhaps you mean for the 8 bits to be = used somewhat hierarchically for naming areas in multi-level or the like bu= t it doesn't sound like that. Going to a flat 24-bit nickname seems like it= , in general, requires new silicon and biases the design towards high end s= witches with bigger tables, etc. If you need new silicon anyway, I think th= at adding 16-bits with a fixed hierarchy split of the upper and lower 16-bi= t parts and using something like the "swap nickname" logic suggest in draft= -perlman-trill-rbridge-mulilevel-04.txt would enable forwarding tables to r= emain small and better support a wider range of switches. [Answer] How upper 8 bits be used to construct the 24 bit address is an adm= inistrative manner. We did not want to go 32 bit address space, then we are= facing the question why TRILL lets use IP in place TRILL.=20 Thanks, Donald =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D Donald E.

This draft is a work item of the Transparent Interconnection of Lots of Li= nks Working Group of the IETF. Title : TRILL: Clarifications, Corrections, and Updates Author(s) : Donald Eastlake Mingui Zhang Anoop Ghanwani Vishwas Manral Ayan Banerjee Filename : draft-ietf-trill-clear-correct-05.txt Pages : 30 Date : 2012-07-16 Abstract: The IETF TRILL (TRansparent Interconnection of Lots of Links) protocol provides least cost pair-wise data forwarding without configuration in multi-hop networks with arbitrary topology and link technology, safe forwarding even during periods of temporary loops, and support for multipathing of both unicast and multicast traffic. TRILL accomplishes this by using IS-IS (Intermediate System to Intermediate System) link state routing and by encapsulating traffic using a header that includes a hop count. Since the TRILL base protocol was approved in March 2010, active development of TRILL has revealed errata in the original RFC 6325 and some cases that could use clarifications or updates. RFC 6327 and RFC 6439 provide clarifications and updates with respect to Adjacency and Appointed Forwarders. This document provides other known clarifications, corrections, and updates to RFC 6325, RFC 6327, and RFC 6439.

Hi Authors,

 

I am not able to understand the meaning of the follo= wing line in this draft: http://= tools.ietf.org/pdf/draft-ietf-trill-esadi-00.pdf

 

“For robustness, if an ESADI instance has two = or more ESADI neighbors

   and is not DRB and it receives no ESADI= -CSNP PDUs for at least the

   CSNP Time (see Section 6.1) of the DRB,= it MAY transmit an ESADI-

   CSNP.”

 

This line is a part of section 4.1 (Sending of ESADI= PDUs) on page number 12.

Please explain me what this line tries to convey.

 

Regards,

Swet

Or is it that you don't understand what the reason is for this behavior? The idea is that if the DRB on an ESADI virtual link is being flakey or the virtual link is broken then, to maintain LSP synchronization, it would be good for some other TRILL switch on that ESADI virtual link to occasionally send a CSNP. The multi-hop ESADI pseudo-link is inherently somewhat less reliable that a link between adjacent TRILL switches. (You might think this could result in a flurry of CSNPs but note that, due to the jitter in the IS-IS reliable flooding mechanism, if there were several non-DRB TRILL switches on the link, as soon as one sends a CSNP it will inhibit the others for a while.) Anyway, although it doesn't make much difference. It should probably say "one" instead of "two" in the text and it should not just be that it has not received a CSNP but that it has not received or sent a CSNP. So, I think the wording should be changes to: "For robustness, if an ESADI instance has one or more ESADI neighbors and is not DRB and it does not receive or send an ESADI-CSNP PDU for at least the CSNP Time (see Section 6.1) of the DRB, it MAY transmit an ESADI-CSNP."

If sending occasionaly ESADI-CSNPs increases robustness, IMO, the spec should say that and explain which scenarios its useful in. And then, MAY doens't seem right either. SHOULD would seem to make more sense... The RFC 2119 defintion of MAY says: 5. MAY This word, or the adjective "OPTIONAL", mean that an item is truly optional. One vendor may choose to include the item because a particular marketplace requires it or because the vendor feels that it enhances the product while another vendor may omit the same item. An implementation which does not include a particular option MUST be prepared to interoperate with another implementation which does include the option, though perhaps with reduced functionality. In the same vein an implementation which does include a particular option MUST be prepared to interoperate with another implementation which does not include the option (except, of course, for the feature the option provides.) which doesn't seem to match the explanation for why the MAY sentence is in the document.

The most significant of these is that it > clarifies that packets are not forwarded through overloaded RBridges. > If you have a problem with any of these changes, please tell me or > post to the list. I took the above as an opportunity to review what the various TRILL specs say about handling "overload" situations. I gather that an overloaded RB sets the overload bit in its IS-IS advertisement to indicate "I have problems and may not work right". OK. But what exactly are other RBs supposed to do with this info? I would assume that for correctness/consistency, the safest thing to do is simply remove the RB from the topology and pretend it doesn't exist. i.e, stop using it or trying to forward traffic through it. Yes, this may result in suboptimal routes (or worse), but at least you'll get consistent behavior. If TRILL continues to forward traffic through RBs that aren't working right, you'll likely see more random/intermittent problems that are hard to debug/diagnose. That said, the clear-correct draft does say if the AF is the only RB connected to a particular VLAN at an edge, if you remove that RB from TRILL, the VLAN becomes unreachable. So it says don't do that. But going through the various spec, the published RFCs don't seem to say anything about the overload bit. (I didn't do an exhaustive search, but searching for the string "overload" in the RFCs shows almost nothing.) Where is the TRILL behavior wrt to using the overload flag documented?

If each RB participating in the ESADI instance included the sequence number of its own LSP in its Hello for that ESADI instance, wouldn't that work? We need to have each RB (in the ESADI instance) send Hellos periodically anyway.

Well, it really just means that the link state database has overflowed. Thus the RBridge can't hold it all and anything that it would calculate from that database, such as least cost paths, could be wrong. > OK. But what exactly are other RBs supposed to do with this info? Except as specified in this draft, they should do what ISO/IEC 10589:2002 (the base IS-IS standard) says. ISO 10589 only talks about unicast data but has appropriate provisions so that if there are only scattered Intermediate Systems in overload, those ISs can still originate and terminate packets but can't act as transit nodes. > I would assume that for correctness/consistency, the safest thing to > do is simply remove the RB from the topology and pretend it doesn't > exist. i.e, stop using it or trying to forward traffic through > it.

If you remove it from the topology, then no packets can reach and possibly none can be originated by it. This makes maintenance (like logging into it and re-booting it) harder. So it stays in the topology and frames can be routed to it, but least cost paths are not allowed that would go through it. (As I say, this only works for scattered overloaded ISs. If you had a dense cluster of them, those on the inside of the cluster, at least, would be unable to communicate.) > That said, the clear-correct draft does say if the AF is the only RB > connected to a particular VLAN at an edge, if you remove that RB from > TRILL, the VLAN becomes unreachable.

As I say, the base behavior is the ISO standard. The Clarifications and Corrections draft extends that to cover multi-destination frames, for example.

Then by all means please have the spec say that. The whole point of a standard is to provide useful guidance to an implementor on whether and when something should be implemented. Many (most?) implementors will not be familiar with TRILL and its long WG history and will just be going by what the spec says.

1)

The ESADI protocol objectives as stated in the draft-04, IMO needs added statements.
Section 1: "Introduction"
>>
The ESADI
   protocol's potential advantages over data plane learning include the
   following:

   1. Security advantages:..
   2. Fast update advantages:..
<<

w.r.t to Security advantages, albeit ESADI can make a authenticated entries an insecure ESADI increases
the security vulnerability then without it. My recommendation is to recommend a SHOULD clause to implement
security features. A secured deployment of TRILL may choose to live with a unsecured ESADI ( & therefore
possibly a more efficient/lighter ESADI); whilst a TRILL plane bridging 3rd party aggregation and application
layers may choose for trusted/secured model.
2)
This is w.r.t to learning of ESADI entries and timing them out. As per RFC 6325, the entries are expected
to be removed only by the originating RBridge.
>>
Section 4.8.3
“The situation is different for end-station address information acquired via the TRILL ESADI protocol. 
It is up to the originating RBridge to decide when to remove such information from its ESADI LSPs 
(or up to ESADI protocol timeouts if the originating RBridge becomes inaccessible).”
<<
 For robust behavior it would be better to timeout the entries without depending on ESADI, the reason 
is a (wrong)ESADI directed forwarding can cause persistent traffic loss, unlike a best effort flood everywhere 
situation. Therefore my recommendation is the specs should not 'mandate' the timing out behavior.

Best Regards,

Hi,

Thanks for the response.

1.) The unsecured ESADI's, potential security issue, could be documented in the "Security Considerations" section.
2.) The ESADI learned entry behavior,I agree with you explanation; however the base RFC 6325 is not exactly worded so.
I would recommend if the correction can be added in the next RFC update or clear-correct changes.

   For end-station address information locally learned from frames
   received, the time out from the last time a native frame was received
   or decapsulated with the information conforms to the recommendations
   of [802.1D].  It is referred to as the "Ageing Time" and is
   configurable per RBridge with a range of from 10 seconds to 1,000,000
   seconds and a default value of 300 seconds.

   The situation is different for end-station address information
   acquired via the TRILL ESADI protocol.  It is up to the originating
   RBridge to decide when to remove such information from its ESADI LSPs
   (or up to ESADI protocol timeouts if the originating RBridge becomes
   inaccessible).

 [trill] ESADI draft change suggestion







Hi,

1)

The ESADI protocol objectives as stated in the draft-04, IMO needs added statements.
Section 1: "Introduction"
>>
The ESADI
  protocol's potential advantages over data plane learning include the
  following:

  1. Security advantages:..
  2. Fast update advantages:..
<<

w.r.t to Security advantages, albeit ESADI can make a authenticated entries an insecure ESADI increases
the security vulnerability then without it. My recommendation is to recommend a SHOULD clause to implement
security features. A secured deployment of TRILL may choose to live with a unsecured ESADI ( & therefore
possibly a more efficient/lighter ESADI); whilst a TRILL plane bridging 3rd party aggregation and application
layers may choose for trusted/secured model.

[Hongjun] Although security is one of ESADI's potential advantanges, but it is not a focal point in that draft. ESADI draft focuses on the general mechanism of ESADI protocol, then an ESADI instance can find its neighbors, exchange end station addresses and keep link state database synchronization with its neighbors. How an ESADI obtains its security features is out of the scope of that spec. Since there will be much work to do if we consider the security features, I think it is more suitable to discuss those features in a new draft than that spec. Therefore, I do not think such a "SHOULD clause" is suitable in that spec.
2)
This is w.r.t to learning of ESADI entries and timing them out. As per RFC 6325, the entries are expected
to be removed only by the originating RBridge.
>>
Section 4.8.3
“The situation is different for end-station address information acquired via the TRILL ESADI protocol.
It is up to the originating RBridge to decide when to remove such information from its ESADI LSPs
(or up to ESADI protocol timeouts if the originating RBridge becomes inaccessible).”
<<
For robust behavior it would be better to timeout the entries without depending on ESADI, the reason
is a (wrong)ESADI directed forwarding can cause persistent traffic loss, unlike a best effort flood everywhere
situation. Therefore my recommendation is the specs should not 'mandate' the timing out behavior.

[Hongjun] The spec gives two most common conditions under which an ESADI to time out some MAC addresses learned via ESADI (i.e., being told to do so by the originating RBridge or finding the originating RBridge inaccessible). But it does not mandate or imply that an ESADI can forget the learned MACs via ESADI only under the two conditions. Besides the two conditions, an ESADI can also decide to forget some learned MACs via ESADI based on local configured polices, for example, configured by administrator not to learn MACs from a specific ESADI RBridge.


Best Regards,
-Sujay

My recommendation is to I don't see why that would be true. If you are just learning from the data plane, a forged multi-destination broadcast frame, either native or TRILL Data, can cause bad MAC learning entries pretty easily throughout the VLAN of the frame. Even an insecure ESADI is a little better. To forge an ESADI frame that would be accepted, an adversary would have to participate in the ESADI instance, create an acceptable ESADI-LSP, make sure it didn't get back to the claimed originator so the claimed originator does not send out a new one with incremented sequence number to overwrite the forged ESADI information, etc. Of course, I'm not claiming that "insecure ESADI" is secure; I'm just saying it seems to me to be a little harder for an adversary to cause bad MAC learning with ESADI than with data plane learning. > recommend a SHOULD clause to implement > security features. A secured deployment of TRILL may choose to live with = a Given that, as far as I can recall, there is no "SHOULD" in TRILL to use any IS-IS authentication, although it is mentioned as a facility available as a countermeasure against some threats, I don't see how it makes sense to just put in a "SHOULD" for ESADI authentication. On the other hand, it might make sense to say that if IS-IS authentication is in use for IS-IS LSPs, then the default would be to use authentication for ESADI. This would be similar to the provisions in the BFD over TRILL draft. > unsecured ESADI ( & therefore > possibly a more efficient/lighter ESADI); whilst a TRILL plane bridging 3= rd > party aggregation and application > layers may choose for trusted/secured model. > > 2) > > This is w.r.t to learning of ESADI entries and timing them out.

Therefore my recommendation is the specs should not 'mandate' = the > timing out behavior. That's not how link state works. In general, you have to retain the link state information from a remote router until you get an update or until that remote router leaves the topology. And in the later case, you still generally want to keep it around for a while (but not actually use it) to minimize the effort to get the link state synchronized if the remote router re-joins the topology. Assume, for example, you have disabled data plane learning and are depending on ESADI. How does it make any sense to "timeout" ESADI data from a remote RBridge and suddenly have to send as unknown location unicast the frames destined for MAC addresses attached to that remote RBridge, which you had been informed about through ESADI? Perhaps the wording could be clarified, but I don't see how it makes any sense to "timeout" ESADI state from a remove RBridge as long as that RBridge is still reachable and participating in ESADI, etc. And I don't see how it makes any sense, assuming you are retaining the ESADI state from such a remote RBridge, to "timeout" making use of that state.

I don't see how it makes any difference. Since the RBridge doing this is going to drop out of the ESADI instance anyway, the MAC Reachability information it was originating is going to be ignored or discarded soon anyway. I think sending out this final "empty" LSP information just gets the word out a little faster. > Q) In case if ESADI rbridge is AF for a vlan-x and the only End Station > which was connected earlier, is removed now, then what will be sent in > ESADI-LSP to flush L2 entries for that > vlan-x, will it be without MAC Reachability TLV? Please bear in mind > that the RBridge has not lost AF for that particular vlan, but has no End > Station to send in MAC Reachability > TLV. Again, I don't see how it makes any difference whether it sends an empty MAC Reachability TLV or send no MAC Reacability TLVs. Why can't implementations do whichever is most convenient? (I suppose not sending any MAC Reachability TLVs saves a tiny number of bytes...) > Please let me know for an ESADI RBridge how to distinguish between > > 1> when to remove learned L2 entries and The way I look at it, an RBridge has number of sources of "MAC&VLAN -> egress nickname" mapping entries. There are entries it has learned from the data plane (possibly empty if data plane learning has been disabled) or from Layer 2 registration protocols. There may be entries in its ESADI state for various VLANs if it is participating in ESADI. There can be manually configured mappings. When any of these sources of mapping change, the RBridge makes the appropriate change in its forwarding tables. You "remove learned L2 entries" on a different basis for different sources. For data plane learning, it is timeout. For ESADI, it is state flooding. Etc. > 2> when to remove ESADI instance neighbor on receiving ESADI-LSP? I think the mechanisms for recognizing ESADI instance neighbors in the current draft are too complicated and can probably be simplified as well as clarified.

This draft is a work item of the Transparent Interconnection of Lots of Li= nks Working Group of the IETF. Title : TRILL: Clarifications, Corrections, and Updates Author(s) : Donald Eastlake Mingui Zhang Anoop Ghanwani Vishwas Manral Ayan Banerjee Filename : draft-ietf-trill-clear-correct-06.txt Pages : 31 Date : 2012-07-30 Abstract: The IETF TRILL (TRansparent Interconnection of Lots of Links) protocol provides least cost pair-wise data forwarding without configuration in multi-hop networks with arbitrary topology and link technology, safe forwarding even during periods of temporary loops, and support for multipathing of both unicast and multicast traffic. TRILL accomplishes this by using IS-IS (Intermediate System to Intermediate System) link state routing and by encapsulating traffic using a header that includes a hop count. Since the TRILL base protocol was approved in March 2010, active development of TRILL has revealed errata in the original RFC 6325 and some cases that could use clarifications or updates. RFC 6327 and RFC 6439 provide clarifications and updates with respect to Adjacency and Appointed Forwarders. This document provides other known clarifications, corrections, and updates to RFC 6325, RFC 6327, and RFC 6439.
