This draft is a work item of the Softwires of the IETF. Title : RADIUS Attribute for Softwire Address plus Port based Mechanisms Authors : Sheng Jiang Yu Fu Bing Liu Peter Deacon Chongfeng Xie Tianxiang Li Filename : draft-ietf-softwire-map-radius-09.txt Pages : 21 Date : 2017-01-03 Abstract: IPv4-over-IPv6 transition mechanisms provide both IPv4 and IPv6 connectivity services simultaneously during the IPv4/IPv6 co-existing period. The Dynamic Host Configuration Protocol for IPv6 (DHCPv6) options have been defined to configure Customer Edge (CE) in MAP-E, MAP-T, and Lightweight 4over6. However, in many networks, the configuration information may be stored in the Authentication Authorization and Accounting (AAA) servers, while user configuration is mainly provided by the Broadband Network Gateway (BNG) through the DHCPv6 protocol.

Document: draft-ietf-softwire-multicast-prefix-option-11 Reviewer: Roni Even Review Date:2017-1-9 IETF LC End Date: 2017–1-12 IESG Telechat date: Summary: This draft is almost ready for publication as a standard track RFC. Major issues: Minor issues: 1. In section 4 first paragraph say “DHCP servers supporting OPTION_V6_PREFIX64 should be configured with U_PREFIX64 and at least one multicast PREFIX64 (i.e., ASM_PREFIX64 and/or SSM_PREFIX64).” From the rest of the section I understand that for SSM deployments both U_PREFIX64 and SSM_PREFIX64 MUST be configured. What is the reason for “should” in the first paragraph? Are there cases where ASM_PREFIX64 or ASM_PREFIX64 and SSM_PREFIX64 are specified and there is no need to specify U_PREFIX64, maybe these cases should be described. Nits/editorial comments: 1. RFC2119 keywords in the document are sometime capitalized and sometime not. I think it will be good to have consistency and if they do not intend to have RFC2119 semantics some other words should be used From nobody Sun Jan 8 23:43:12 2017 Return-Path: X-Original-To:

03:55:02 -0000 Reviewer: Sheng Jiang Review result: Has Nits Summary: This draft is almost ready for publication as a standard track RFC. Major issues: Minor issues: “the specification of a DHCPv6 option that could be used to discover unicast PREFIX64s in environments where multicast is not enabled. Such side effect conflicts with the recommendation documented in Section 6 of [RFC7051].” It is unclear how the Section 6 of RFC7051 relevant with the content above. It would be necessary to quote particular content of RFC7051 and give necessary analysis. Nits: “the Pv4 multicast address is inserted in the last 32 bits of the IPv4-embedded IPv6 multicast address.” Pv4//IPv4 From nobody Mon Jan 9 22:44:10 2017 Return-Path: X-Original-To:

Major issues: 1. The DHCPv6 option format. The format used (3 prefixes stuffed in a single option) are not the preferred way to convey this kind of information. This format is against the recommendation of DHCPv6 Option Guidelines (RFC7227). See section 5.3 of that RFC. This is not a nit-pick. There are a number of strong arguments for favouring 3 simple options over one complex one. Here they are: - implementing simple option is trivial as this format is already supported by most DHCPv6 implementations, so it's a matter of extending existing code to cover additional option codes. - deploying is easier. Many implementations allow to define this kind of option with configuration change and no need for software change. - better handling of optional prefixes. Section 3 says that the asm-length, ssm-length and unicast-length can be 0. This means that depending on the deployment, all of those fields are optional. This would be better handled with separate options that are simply not configured on the server when not needed. - better failure recovery. The text in section 2 says that some of the prefixes are supposed to belong to well known prefixes. What the client is supposed to do when the server sends a value that does not meet that criteria? With a single option you'd have some sort of unclear decision tree to ignore part of the option content. With 3 separate options, it's simple - ignore the whole option. Now, there's one complication here: scope preservation. I'm not familiar with the multicast technologies you're configuring, so I won't make any specific recommendations here. If you send multiple instances of the ASM, SSM and prefix64, are they logically grouped together? My understanding is that the scope is encoded on the second octet of the multicast address, right? So when you send multiple instances, it should be possible to preserve the scope by matching whatever scope you have in IPv4 with the IPv6 prefix with the same scope. I don't claim to know much about multicast, though. I may be wrong on this. Now, if you considered all of the above, read RFC7227 and still believe that having a single option rather than 3 is better way to go, I won't insist. But you should add an explanation of the benefits of having a single complex option that outweigh the simplicity proposed by 7227. Minor issues: 2. The explanation in last paragraph in Section 3 doesn't work for me. It says one option rather than three are easier to detect environments where multicastis not enabled. Not configuring 3 options is as simple as not configuring 1 option. Also, the text references Section 6 of RFC7051, which only says nothing about one complex vs three simple options. It just says the DHCPv6 server and client code has to be modified. If you want to follow that recommendation, using 3 options is actually easier, because you can configure most clients and server with custom options. That's a big plus for easier deployment when you can just tweak the config file and be done rather than needing a new version of the software. 3. Failure recovery. The text doesn't say what the client is supposed to do when the server is misconfigured. In particular, if the prefixes are supposed to belong to well known pools (e.g. a supposedly multicast prefix that does not start with ff), what to do when they aren't. Should just that prefix be discarded or the whole option? 4. What's the allowed prefix length is for ASM_PREFIX64 and SSM_PREFIX64 is? Section 4, 2nd paragraph says it must be /96, but section 3 says allowed values are from 0 to 128. As a DHCPv6 client and server implementor, I'm confused what sanity checks I'm supposed to implement here. Those two paragraphs seem to contradict each other. 5. Nit: I would add "DHCPv6" in the title of section 4. 6. Nit: Section 5: "DHCPv6 client MUST include OPTION_V6_PREFIX64 in its OPTION_ORO." => "DHCPv6 client MUST include OPTION_V6_PREFIX64 code in its OPTION_ORO". That's it. IANA asked me to formulate my opinion on this draft no later than Jan. 17th, so I'd appreciate authors' response before that date.

This draft is a work item of the Softwires of the IETF. Title : Softwire Mesh Multicast Authors : Mingwei Xu Yong Cui Jianping Wu Shu Yang Chris Metz Greg Shepherd Filename : draft-ietf-softwire-mesh-multicast-15.txt Pages : 19 Date : 2017-01-10 Abstract: The Internet needs to support IPv4 and IPv6 packets. Both address families and their related protocol suites support multicast of the single-source and any-source varieties. During IPv6 transition, there will be scenarios where a backbone network running one IP address family internally (referred to as internal IP or I-IP) will provide transit services to attached client networks running another IP address family (referred to as external IP or E-IP). It is expected that the I-IP backbone will offer unicast and multicast transit services to the client E-IP networks. Softwire Mesh is a solution providing E-IP unicast and multicast support across an I-IP backbone. This document describes the mechanism for supporting Internet-style multicast across a set of E-IP and I-IP networks supporting softwire mesh. We focus on IPv4- over-IPv6 scenario in this document, due to lack of real-world use cases for IPv6-over-IPv4 scenario. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-softwire-mesh-multicast/ There's also a htmlized version available at: https://tools.ietf.org/html/draft-ietf-softwire-mesh-multicast-15 A diff from the previous version is available at: https://www.ietf.org/rfcdiff?url2=draft-ietf-softwire-mesh-multicast-15 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

IDnits complain about one instance of lines with non-rfc3849-compliant IPv6 addresses. That should be verified whether it actually is an issue. On the operations side, I am happy with the current deployment considerations section content, and in general how some of the deployment/operational aspects have been laid out in the document.

The DHCPv6 option format. The format used (3 prefixes stuffed in a > single option) are not the preferred way to convey this kind of > information. This format is against the recommendation of DHCPv6 Option > Guidelines (RFC7227). See section 5.3 of that RFC. This is not a > nit-pick. There are a number of strong arguments for favouring 3 simple > options over one complex one. Here they are: >=20 [Med] I'm aware of RFC7227 but the design of one single option is on purpos= e as recorded in the document:=20 Note that it was tempting to define three distinct DHCPv6 options, but that approach was not adopted because it has a side effect: the specification of a DHCPv6 option that could be used to discover unicast PREFIX64s in environments where multicast is not enabled. Such side effect conflicts with the recommendation documented in Section 6 of [RFC7051]. We don't want to interfere with unicast-only recommendation in RFC7051. Thi= s DHCPv6 option is only used for multicast IPv4 service continuity. =20 Note, the encoding of the IPv6 prefix follows the one in https://tools.ietf= .org/html/rfc7227#section-5.3. It would be easy to define those as standalo= ne options, but we are not doing that for the reason I mentioned above and = for another technical reason that I'm discussing below. =20 > - implementing simple option is trivial as this format is already > supported by most DHCPv6 implementations, so it's a matter of extending > existing code to cover additional option codes. >=20 > - deploying is easier. Many implementations allow to define this kind of > option with configuration change and no need for software change. >=20 > - better handling of optional prefixes. Section 3 says that the > asm-length, ssm-length and unicast-length can be 0. This means that > depending on the deployment, all of those fields are optional. This > would be better handled with separate options that are simply not > configured on the server when not needed. >=20 > - better failure recovery. The text in section 2 says that some of the > prefixes are supposed to belong to well known prefixes.

So when you send multiple instances, it should > be possible to preserve the scope by matching whatever scope you have in > IPv4 with the IPv6 prefix with the same scope. I don't claim to know > much about multicast, though. I may be wrong on this. [Med] The problem is that distinct IPv4 prefixes may be used for each of th= ese scopes: the issue then is how to associate each multicast prefix and un= icast prefix. With the current encoding, this is not an issue. =20 >=20 > Now, if you considered all of the above, read RFC7227 and still believe > that having a single option rather than 3 is better way to go, I won't > insist. [Med] Ok, thanks. But you should add an explanation of the benefits of having a > single complex option that outweigh the simplicity proposed by 7227. [Med] There is already the text I quoted above that calls out this point. P= lease let me know if you think that more text is needed. =20 >=20 > Minor issues: >=20 > 2. The explanation in last paragraph in Section 3 doesn't work for me. > It says one option rather than three are easier to detect environments > where multicastis not enabled. Not configuring 3 options is as simple as > not configuring 1 option. Also, the text references Section 6 of > RFC7051, which only says nothing about one complex vs three simple > options.

[Med] Actually, I'm not trying to argue in favor or against the text in Sec= tion 6 of RFC7051. The key point from that section is: it is recommended to= use the Well-Known DNS Name heuristic discovery-based method for unicast-o= nly environments. I changed the text to make this clear:=20 OLD: Such side effect conflicts with the recommendation documented in Section 6 of [RFC7051]. NEW: Such side effect conflicts with the recommendation to support the Well-Known DNS Name heuristic discovery-based method for unicast-only environments (Section 6 of [RFC7051]). >=20 > 3. Failure recovery. The text doesn't say what the client is supposed to > do when the server is misconfigured. In particular, if the prefixes are > supposed to belong to well known pools (e.g. a supposedly multicast > prefix that does not start with ff), what to do when they aren't. Should > just that prefix be discarded or the whole option? [Med] The checks whether the received prefix is a multicast prefix + (it is= in ASM range for ASM, it is in the SSM range for SSM) is up to the multica= st library not the DHCP client. We didn't want to overload the client with = such processing that is done anyway by the multicast client that will make = use of these prefixes. >=20 > 4.

The Routing Directorate seeks to review all routing or routing-related drafts as they pass through IETF last call and IESG review, and sometimes on special request. The purpose of the review is to provide assistance to the Routing ADs. For more information about the Routing Directorate, please see http://trac.tools.ietf.org/area/rtg/trac/wiki/RtgDir Although these comments are primarily for the use of the Routing ADs, it would be helpful if you could consider them along with any other IETF Last Call comments that you receive, and strive to resolve them through discussion or by updating the draft. Document: draft-ietf-softwire-dslite-multicast-14.txt Reviewer: Stig Venaas Review Date: 2017-01-11 IETF LC End Date: 2017-01-12 Intended Status: Standards Track Summary: I have some minor concerns about this document that I think should be resolved before publication. Comments: The document is fairly easy to read, and the solution is technically sound and is well described. But a couple of statements are technically wrong and need to be corrected. A few more details could be added in some places, and there are a couple of very minor issues that make it less readable. Major Issues: No major issues found. Minor Issues: In 3 places the documents talks about the MLD querier where it instead should have said PIM Designated Router, or PIM DR. In section 2 we have this definition: Multicast B4 (mB4): a functional entity which supports an IGMP-MLD interworking function (refer to Section 6.1) that relays information conveyed in IGMP messages by forwarding the corresponding Multicast Listener Discovery (MLD) messages towards the MLD Querier in the IPv6 network. In addition, the mB4 decapsulates IPv4-in-IPv6 multicast packets. It is the DR, not the querier that needs the reports. The reports are sent by multicast to the all MLDv2-capable routers address though, which means that DR, querier (they may be the same), and potentially other routers on the link will get the report. Maybe you can skip some details and just say that mB4 sends an MLD report. In 4.2 we have this paragraph: The mB4 uses the G6 (and both S6 and G6 in SSM) to create the corresponding MLD Report message. The mB4 sends the Report message towards the MLD Querier in the IPv6 network. The MLD Querier (which usually acts as the PIMv6 Designated Router too) receives the MLD Report message and sends the PIMv6 Join to join the IPv6 multicast distribution tree. The MLD Querier can send either PIMv6 Join (*,G6) in ASM or PIMv6 Join (S6,G6) in SSM to the mAFTR. It should just say DR here as well. Also in In 6.1 it says: MLD messages are forwarded natively towards the MLD Querier located upstream in the IPv6 network (i.e., the first hop IPv6 router). It should refer to the PIM DR here as well, and figure 2 should be updated. More discussion about SSM vs ASM would be useful. In the last paragraph of section 1 you have some text about SSM versus ASM. would be good to point out that SSM and ASM IPv4 groups should be mapped to SSM and and ASM IPv6 groups respectively. That is, if an IPv4 group is an SSM group, then I believe the respective IPv6 group needs to be SSM as well. The same for ASM. In 4.2 it says: The mAFTR acts as the IPv4 DR to which the uPrefix64-derived S6 is connected. Shouldn't it say that the mAFTR acts as the IPv6 DR? Nits: I found a number of nits. In the abstract we have: This document specifies a solution for the delivery of IPv4 multicast services to IPv4 clients over an IPv6 multicast network. The solution relies upon a stateless IPv4-in-IPv6 encapsulation scheme and uses the IPv6 multicast distribution tree to deliver IPv4 multicast traffic. The solution is particularly useful for the delivery of multicast service offerings to DS-Lite serviced customers. This make it sounds like a single IPv6 multicast tree is used for delivery of all IPv4 multicast. It would be better changing this to plural (or possible say an IPv6 multicast distribution tree). In first paragraph of section 1: DS-Lite [RFC6333] is a technique that rationalizes the usage of the remaining global IPv4 addresses during the transition period by sharing a single IPv4 address with multiple users. Rationalize is the wrong word here I believe. Perhaps it should say rations, limits or reduces? In second paragraph of section 2, [RFC7597] is not marked correctly as a reference, it is just text. In 4.2 we have this text: The mAFTR advertises the route of uPrefix64 with an IPv6 Interior Gateway Protocol (IGP), so as to represent the IPv4-embedded IPv6 source in the IPv6 multicast network, and to run the Reverse Path Forwarding (RPF) check procedure on incoming multicast traffic. It might sound like mAFTR is the router doing the RPF check. It might be good to clarify that it is announced to allow other IPv6 routers to perform RPF check. In 6.2 you have this example: As an illustration, if a packet is received from source 2001:db8::192.0.2.33 and needs to be forwarded to group ff3x:1000::233.252.0.1 Note that the latter is not a valid unicast prefix-based multicast address. It would be better to use something like ff3x:20:2001:db8::233.252.0.1. This is also the case in 7.4. In 6.5 there is an issue with the example. It has the address ff0e::db8::233.252.0.1. You cannot use :: twice. The section 7.5 heading is TTL/Scope, but it only discusses Scope. It might make sense to recommend copying the TTL value from the IPv4 packet to the IPv6 packet, and perhaps copying it back after decapsulation. I don't understand section 8.1.1 about co-locating MLD querier with the mAFTR. Doesn't that mean that the mAFTR is on the same link as the mB4? If that is the case, do you need IPv6 encapsulation at all? Would it make sense to consider the case where mB4 acts as an IPv6 PIM router, avoiding sending MLD reports? Appendix B discusses issues with mismatch of group membership protocols at mB4. The real issue, which is not mentioned, is if mB4 receives source specific (SSM) reports from IPv4 receivers, and the upstream IPv6 MLD router only supports MLDv1.

Document: draft-ietf-softwire-dslite-multicast-14.txt
Reviewer: Stig Venaas
Review Date: 2017-01-11
IETF LC End Date: 2017-01-12
Intended Status: Standards Track

Summary:
I have some minor concerns about this document that I think should be
resolved before publication.

Comments:
The document is fairly easy to read, and the solution is technically
sound and is well described. But a couple of statements are
technically wrong and need to be corrected. A few more details could
be added in some places, and there are a couple of very minor issues
that make it less readable.

Major Issues:
No major issues found.

Minor Issues:

In 3 places the documents talks about the MLD querier where it instead
should have said PIM Designated Router, or PIM DR.

=E2=80=8B[Q]: Yes, we borrowed the &= quot;Querier" terminology heavily from RFC 3810.
can we = simply replace it with "router" or just remove it somewhere like<= br>
"... into the IPv6 network"? Since as you mentioned= there may be querier, DR
and other routers receiving the mes= sage.
=C2=A0=E2=80=8B
In section 2 we have this definition:

= =C2=A0
It is the DR, not the querier that needs the reports. The reports are
sent by multicast to the all MLDv2-capable routers address though,
which means that DR, querier (they may be the same), and potentially
other routers on the link will get the report. Maybe you can skip some
details and just say that mB4 sends an MLD report.

In 4.2 we have this paragraph:
=C2=A0 =C2=A0
=E2=80=8B=E2=80=8B
The mB4 uses the G6 (and both S6 = and G6 in SSM) to create the
=C2=A0 =C2=A0corresponding MLD Report message.=C2=A0 The mB4 sends the Repo= rt message
=C2=A0 =C2=A0towards the MLD Querier in the IPv6 network.=C2=A0 The MLD Que= rier (which
=C2=A0 =C2=A0usually acts as the PIMv6 Designated Router too) receives the = MLD

=C2=A0 =C2=A0in ASM or PIMv6 Join (S6,G6) in SSM to the mAFTR.

It should just say DR here as well.

Also in In 6.1 it says:
=C2=A0 =C2=A0
=E2=80=8B=E2=80=8B
MLD messages are forwarded native= ly towards the MLD Querier
=C2=A0 =C2=A0located upstream in the IPv6 network (i.e., the first hop IPv6=
=C2=A0 =C2=A0router).
It should refer to the PIM DR here as well, and figure 2 should be updated.=

=E2=80=8B[Q]:

-New-
= =E2=80=8B
=C2=A0
=E2=80=8BMLD messages are forwarded natively towa= rds the MLD router

router).
=E2=80=8B
More discussion about SSM vs ASM would be useful. In the last
paragraph of section 1 you have some text about SSM versus ASM. would
be good to point out that SSM and ASM IPv4 groups should be mapped to
SSM and and ASM IPv6 groups respectively. That is, if an IPv4 group is
an SSM group, then I believe the respective IPv6 group needs to be SSM
as well. The same for ASM.

=E2=80=8B[Q]: The quote here is just inte= nt to express the preference of SSM.
We can remove
"=
the
operation of the translation mechanism is also simplified when S= SM is
used, e.g., considerations for placement of the IPv6 the Rendezvou= s
Point (RP) are no longer relevant.
"
from the last sentence= to make it simple.
=E2=80=8B
=C2=A0
In 4.2 it says:
=C2=A0 =C2=A0
=E2=80=8B=E2=80=8B
The mAFTR acts as the IPv4 DR to = which the uPrefix64-derived S6 is
=C2=A0 =C2=A0connected.
Shouldn't it say that the mAFTR acts as the IPv6 DR?

=E2=80=8B[Q]: Yes.
=E2=80=8B
=C2= =A0

Nits:
I found a number of nits.

In the abstract we have:
=C2=A0 =C2=A0This document specifies a solution for the delivery of IPv4 mu= lticast
=C2=A0 =C2=A0services to IPv4 clients over an IPv6 multicast network.=C2=A0= The

=C2=A0 =C2=A0delivery of multicast service offerings to DS-Lite serviced =C2=A0 =C2=A0customers.

This make it sounds like a single IPv6 multicast tree is used for
delivery of all IPv4 multicast. It would be better changing this to
plural (or possible say an IPv6 multicast distribution tree).

=E2=80=8B[Q]:Ok, maybe "an IPv6 mult= icast distribution tree".
=E2=80=8B
=C2=A0
In first paragraph of section 1:
=C2=A0 =C2=A0DS-Lite [RFC6333] is a technique that rationalizes the usage o= f the
=C2=A0 =C2=A0remaining global IPv4 addresses during the transition period b= y
=C2=A0 =C2=A0sharing a single IPv4 address with multiple users.
Rationalize is the wrong word here I believe. Perhaps it should say
rations, limits or reduces?

=E2=80=8B[Q]: not native, so no comment o= n it :-)
=E2=80=8B
=C2=A0
In second paragraph of section 2, [RFC7597] is not marked correctly as
a reference, it is just text.

In 4.2 we have this text:
=C2=A0 =C2=A0
=E2=80=8B=E2=80=8B
The mAFTR advertises the route of= uPrefix64 with an IPv6 Interior
=C2=A0 =C2=A0Gateway Protocol (IGP), so as to represent the IPv4-embedded I= Pv6
=C2=A0 =C2=A0source in the IPv6 multicast network, and to run the Reverse P= ath
=C2=A0 =C2=A0Forwarding (RPF) check procedure on incoming multicast traffic= .

It might sound like mAFTR is the router doing the RPF check. It might
be good to clarify that it is announced to allow other IPv6 routers to
perform RPF check.

=E2=80=8B[Q]:
= =E2=80=8B
=C2=A0
-
=E2=80=8BNew-
The = mAFTR advertises the route of uPrefix64 with an IPv6 Interior
Gateway Pr= otocol (IGP), so as to represent the IPv4-embedded IPv6
source in= the IPv6 multicast network, and for IPv6 multicast
routers to run the R= everse Path Forwarding (RPF) check procedure
on incoming multicast traff= ic.
=E2=80=8B


In 6.2 you have this example:
=C2=A0 =C2=A0As an illustration, if a packet is received from source
=C2=A0 =C2=A02001:db8::192.0.2.33 and needs to be forwarded to group
=C2=A0 =C2=A0ff3x:1000::233.252.0.1

Note that the latter is not a valid unicast prefix-based multicast
address. It would be better to use something like
ff3x:20:2001:db8::233.252.0.1. This is also the case in 7.4.

=E2=80=8B[Q]: Ok.

In 6.5 there is an issue with the example. It has the address
ff0e::db8::233.252.0.1. You cannot use :: twice.

=E2=80=8B[Q]: Thanks.

The section 7.5 heading is TTL/Scope, but it only discusses Scope. It
might make sense to recommend copying the TTL value from the IPv4
packet to the IPv6 packet, and perhaps copying it back after
decapsulation.

I don't understand section 8.1.1 about co-locating MLD querier with
the mAFTR. Doesn't that mean that the mAFTR is on the same link as the<= br> mB4? If that is the case, do you need IPv6 encapsulation at all?

=E2=80=8B[Q]: Co-locating means on the sa= me node, running the two sorts of
functionalities.
=E2=80= =8B
=C2=A0
Would it make sense to consider the case where mB4 acts as an IPv6 PIM
router, avoiding sending MLD reports?

=E2=80=8B[Q]: That's possible.
=E2= =80=8B
=C2=A0
Appendix B discusses issues with mismatch of group membership
protocols at mB4. The real issue, which is not mentioned, is if mB4
receives source specific (SSM) reports from IPv4 receivers, and the
upstream IPv6 MLD router only supports MLDv1.

=E2=80=8B[Q]: We have talked about this i= n the next paragraph.

Thanks again for your review.

This draft is a work item of the Softwires of the IETF. Title : Delivery of IPv4 Multicast Services to IPv4 Clients over an IPv6 Multicast Network Authors : Mohamed Boucadair Jacni Qin Christian Jacquenet Yiu L. Lee Qian Wang Filename : draft-ietf-softwire-dslite-multicast-15.txt Pages : 21 Date : 2017-01-12 Abstract: This document specifies a solution for the delivery of IPv4 multicast services to IPv4 clients over an IPv6 multicast network. The solution relies upon a stateless IPv4-in-IPv6 encapsulation scheme and uses an IPv6 multicast distribution tree to deliver IPv4 multicast traffic. The solution is particularly useful for the delivery of multicast service offerings to DS-Lite serviced customers.

This is OK, but I see it says "forwarding the corresponding...". The MLD message is originated by mB4. "Forwarding" is not quote correct. Also, the message only goes to the IPv6 routers that are on the same link as mB4, it may sound like it gets forwarded, but MLD messages are never forwarded. So just think about whether there is a more precise way of saying it. >> >> In 4.2 we have this paragraph: >> The mB4 uses the G6 (and both S6 and G6 in SSM) to create the >> corresponding MLD Report message.

The Querier is entirely out of the picture, so I would just write "The PIMv6 Designated Router receives the MLD Report message and sends"... If you want a reference, maybe see the beginning of https://tools.ietf.org/html/rfc7761#section-3.1 >> Also in In 6.1 it says: >> MLD messages are forwarded natively towards the MLD Querier >> located upstream in the IPv6 network (i.e., the first hop IPv6 >> router). >> It should refer to the PIM DR here as well, and figure 2 should be >> updated. >> > > [Med] This one is really specific to IGMP/MLD. The use of Querier in the = text and the figure are correct. I suggest to maintain the details. I believe this is incorrect. At least the MLD reports sent by mB4 are processed by the PIM DR, not the MLD querier. They can be the same router, but it is always the router functioning as PIM DR that is responsible for acting on the MLD report. In the text you are talking about the MLD report/message sent by mB4. One option could be to replace querier with IPv6 router? Note that "first hop IPv6 router" is also confusing. For multicast, the term "first hop" is used for the router connected to the source. While the router receiving MLD reports (the DR) is the "last hop" router. I would replace this text "MLD messages are forwarded natively towards the MLD Querier located upstream in the IPv6 network (i.e., the first hop IPv6 router)" with something like "MLD messages are sent natively to the directly connected IPv6 multicast routers (it will be processed by the PIM DR)." >> More discussion about SSM vs ASM would be useful.

The MLD querier is on the same link as mB4, right? They must be connected to the same layer 3 link (subnet). So if you say you co-locate MLD querier with the mAFTR, then I believe the mAFTR is on the same link as mB4. Which means that you IPv6 encapsulate between two routers that are on the same layer 3 link. Is this useful?

I understand that you're saying that you downgrade to IGMPv2 if the IPv6 querier is MLDv1. That is fine. But it might be good to point out that you cannot support SSM in that case. To support IPv4 SSM, you need to have MLDv2 in your IPv6 network. Maybe it is obvious, but it might be worth pointing it out.

The ML= D message is originated by mB4. "Forwarding" is not quote correct. Also, the message only goes to the IPv6 routers that are on the same link as mB4, it may sound like it gets forwarded, but MLD messages are never forwarded. So just think about whether there is a more precise way of saying it. [YL] I understand your concerns of the correctness of the protocol behavior= . The mB4 translates and generate the corresponding MLD message. Strictly sp= eaking, no forwarding hs involved. If we change this to: NEW: Multicast B4 (mB4): a functional entity which supports an IGMP-MLD interworking function (refer to Section 6.1) that translates the IGMP messages into the corresponding Multicast Listener=20 Discovery (MLD) messages, and send the MLD messages to the IPv6 network. =20 =20 >> >> In 4.2 we have this paragraph: >> The mB4 uses the G6 (and both S6 and G6 in SSM) to create the >> corresponding MLD Report message.

This draft is a work item of the Softwires of the IETF. Title : Delivery of IPv4 Multicast Services to IPv4 Clients over an IPv6 Multicast Network Authors : Mohamed Boucadair Chao Qin Christian Jacquenet Yiu L. Lee Qian Wang Filename : draft-ietf-softwire-dslite-multicast-16.txt Pages : 21 Date : 2017-01-17 Abstract: This document specifies a solution for the delivery of IPv4 multicast services to IPv4 clients over an IPv6 multicast network. The solution relies upon a stateless IPv4-in-IPv6 encapsulation scheme and uses an IPv6 multicast distribution tree to deliver IPv4 multicast traffic. The solution is particularly useful for the delivery of multicast service offerings to DS-Lite serviced customers.

But I noticed one more thing that you might want to change. I'll leave it to you. 8.1.1. The MLD Querier is Co-Located with the mAFTR The mAFTR can embed the MLD Querier function (as well as the PIMv6 DR) for optimization purposes. I'm wondering if you should say IPv6 DR or PIMv6 DR instead. As you write after the heading, it must be co-located with the DR as well. Normally the querier would be the same router, but the querier could be another router on the link. Then we have this section: 8.1.2. The DR is Co-Located with the mAFTR In the text you talk about the DR connected to the IPv4 source. Hence it is the first hop DR, and IPv4 DR. I'm wondering if it is worth saying IPv4 DR or something in the title to distinguish it from the other DR. Basically we have first hop DR and last hop DR, or if you like IPv4 DR and IPv6 DR. I'm leaving it to you to decide. This is the only remaining issue I can find. There is a typo at the end of Appendix B though. It say "Noet".

This draft is a work item of the Softwires of the IETF. Title : Deployment Considerations for Lightweight 4over6 Authors : Qiong Sun Chongfeng Xie Yiu L. Lee Maoke Chen Tianxiang Li Filename : draft-ietf-softwire-lightweight-4over6-deployment-00.txt Pages : 23 Date : 2017-01-25 Abstract: Lightweight 4over6 is a mechanism which moves the translation function from tunnel lwAFTR (AFTR) to lwB4s (B4s), and hence reduces the mapping scale on the lwAFTR to per-customer level. This document discusses various deployment models of Lightweight 4over6. It also describes the deployment considerations and applicability of the Lightweight 4over6 architecture. The IETF datatracker status page for this draft is: https://datatracker.ietf.org/doc/draft-ietf-softwire-lightweight-4over6-deployment/ There's also a htmlized version available at: https://tools.ietf.org/html/draft-ietf-softwire-lightweight-4over6-deployment-00 Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.

(Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-softwire-multicast-prefix-option/ ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- - (nit) section 3: it seems odd to say in the figure that the prefixes are variable length but to then say the lengths of two of them MUST be 96 bits. (I do think having the fields as is is good for futureproofing, but would suggest changing the figure.) - (non-nit:-) section 3: I'm not getting why the unicast-length can be >96? And what if the prefix length is not one of those given in RFC6052? Don't you need to say it needs to be? - (not sure about nittyness:-) section 5: 1st bullet: I'm not following what "matches" means here. Probably my ignorance but is it clear?

Sheesh. But the WG did consider it and were ok going ahead from a look at the list. (So there's no need to reply to my whining here:-) - 6.3: Is RFC7739 worth a mention here? Not sure myself. - section 9: I'd have thought that this solution reduced the potential for a DoS compared to the previous situation where multicast traffic is mapped to unicast? If so, worth a mention?
