COMMENT:
----------------------------------------------------------------------

Thank you for the discussions around my discuss point, and the ensuing chan= ges
resulting from the discussions!=C2=A0 My apologies that I was tardy in re-r= eviewing after
the updates were made.

I think the core issues have been resolved, but do have a couple comments o= n the -14:

Section 3 says:

=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0 Separate BFD= sessions can be established between the
=C2=A0 =C2=A0VTEPs (IP1 and IP2) for monitoring each of the VXLAN tunnels (= VNI 100
=C2=A0 =C2=A0and 200).=C2=A0 Using a BFD session to monitor a set of VXLAN = VNIs between
=C2=A0 =C2=A0the same pair of VTEPs might help to detect and localize probl= ems
=C2=A0 =C2=A0caused by misconfiguration.=C2=A0 An implementation that suppo= rts this
=C2=A0 =C2=A0specification MUST be able to control the number of BFD sessio= ns that
=C2=A0 =C2=A0can be created between the same pair of VTEPs.=C2=A0 [...]

While the first two sentences are probably true, they are arguably out
of scope for this document, since Section 6 says that BFD control
packets on non-management VNI is outside the scope of this
specification.=C2=A0
GIM>> Yes, the document descri= bes applicability of BFD over the Management VNI. Procedures described in t= he document might work for non-managemnt=C2=A0VNIs but the document doesn&#= 39;t make any assumption about that. And that is why a case of non-manageme= nt VNI was set outside the scope of the specification.
The third sentence is quite surprising i= n the context of
this document only defining BFD for the management VNI, since multiple
BFD sessions on the same VNI seem redundant.
GIM>&g= t; True. The intention was to suggest that if an implementation may be used= on non-management VNIs, then the number of concurrent BFD sessions must be= controlled. I think that it is unlikely that there will be a document that= will define BFD over VXLAN for non-managemet=C2=A0VNIs and developers may = appreciate some guidance this document provides.=C2=A0

Section 5

=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0Destination MAC: A Management VNI, which = does not have any
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0tenants, will have no dedicated MAC addre= ss for decapsulated
=C2=A0 =C2=A0 =C2=A0 =C2=A0 =C2=A0traffic.=C2=A0 The value [TBD1] SHOULD be= used in this field.

While this normative language seems like the appropriate level of
stringency, I do find myself wondering what other value might be used
and why.=C2=A0 (This, of course, need not be answered in the document, thou= gh
it could be if the answer is known and useful.)
GIM>= ;> There are early implementations that have been deployed that use othe= r MAC values. We might disagree with their choice but wanted to allow thier= =C2=A0conformance to this specification.

A few, non blocking, comments: Assigning a single unicast MAC address seems slightly odd in that it isn't globally unique, but I can't think of any good alternative. At the same time, a service layer BFD session may be used between the tenants of VTEPs IP1 and IP2 to provide end-to-end fault management (this use case is outside the scope of this document). In such a case, for VTEPs BFD Control packets of that session are indistinguishable from data packets. "for VTEPs BFD Control" => "for VTEPS, the BFD Control" Ethernet Header: Destination MAC: A Management VNI, which does not have any tenants, will have no dedicated MAC address for decapsulated traffic. The value (TBD1) SHOULD be used in this field. Source MAC: MAC address associated with the originating VTEP. Should the TypeOrLen field in the Ethernet header also be specified (presumably set to IPv4 or IPv6)?

[ sections 3,5 ] * I agree with Eric Vyncke's concerns about the use of ::ffff:127.0.0.0/104 space. This is not especially well-motivated, nor do I think the use of 127.0.0.0/8 is particularly well-motivated. In IPv6, 2001::/23 is reserved for IETF protocol assignments and in my opinion this is an example of where that should be used. There is also still plenty of space to carve out from 192.0.0.0/24 for internal tunnel uses like this. Alternatively, a better approach might be for each VTEP to allocate their own IPv4 and/or IPv6 link-local addresses and uses these addresses for whatever traffic is to be sent within the data plane. If the VTEPs use inner Ethernet headers for this traffic, then this would seem to make more sense to me. [ section 9 ] * It's not clear that the security of a prohibition on routers is sufficiently motivating securit when the packet is logically "switched" because it's on the same (effectively) VLAN. The same router forwarding prohibition applies to link-local IP addresses and these could be used instead. * What prevents a machine like VM1-1 from crafting a packet with the magic destination MAC and src & dst IPs from the magic range? Should there be text about not forwarding any packets from VMs toward the magic dst MAC?

List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 29 Oct 2020 18:28:44 -0000 The IESG has approved the following document: - 'BFD for VXLAN' (draft-ietf-bfd-vxlan-16.txt) as Informational RFC This document is the product of the Bidirectional Forwarding Detection Working Group. The IESG contact persons are Alvaro Retana, Deborah Brungard and Martin Vigoureux. A URL of this Internet Draft is: https://datatracker.ietf.org/doc/draft-ietf-bfd-vxlan/ Technical Summary This document describes the use of the Bidirectional Forwarding Detection (BFD - RFC 5880) protocol in Virtual eXtensible Local Area Network (VXLAN) overlay networks. Working Group Summary This document has received community review with opportunities to comment in relevant working groups such as BFD, NVO3, and BESS. It is of interest to parties that operate VXLAN networks and wish to provide continuity checks for tunnels interconnecting virtual machines in such networks. Document Quality The document received a number of comments during IETF LC and directorate reviews, all of which where addressed. The more important ones related to the use of a special VNI as a management channel, and the use of which MAC DA for the inner ethernet frame. At the time of working group last call, there are two known implementations of this mechanism. No special reviewers were required for this document. Personnel Document Shepherd: Jeffrey Haas, BFD co-chair. Responsible Area Director: Martin Vigoureux.
