Hi Anoop, Larry, Shahram, et. al,
thank you for the correction. We’ll address it in the next update.

Hi Greg,

I think Larry has covered the points I was trying to bring up...if there's a MAC header present, then the VXLAN GPE next header has to indicate "Ethernet" rather than "IPv4" or "IPv6".

Thanks,
Anoop

+BFD WG and RTGWG OOAM DT

Hi Anoop,
thank you for your review and the question. The scope of this draft is only for the VXLAN. The Overlay OAM Desing Team is working on the Requirements, Gap Analysis and, if there will be required, enhancements and/or new OAM protocols for BIER, NSH, VXLAN-GPE, GENEVE, and GUE, as defined in its charter. Would appreciate you review and comments of the two documents the OOAM-DT already presented in BA meeting:

  *   OOAM Requirements
  *   OAM for Overlay Networks: Gap analysis
In the latter you'll find the example to demonstrate applicability of BFD Async mode in BIER domain. As we've discussed, other BFD may be applied to other overlay networks that I've listed above even though their method of indication OAM payload may be different from BIER. Would you agree, or suggest to have another example of BFD?

Regards, Greg

Authors,

In section 4.1, you have this:
>>>

   Next Protocol Field in GPE header MUST be set to IPv4 or IPv6.

...

   The BFD packet MUST be carried inside the inner MAC frame of the

   VxLAN packet.  The inner MAC frame carrying the BFD payload has the

   following format:
>>>

These two statements seem to contradict each other.  If the GPE header indicates IPv4 or IPv6, then how can the BFD packet be encapsulated within a MAC frame?

Can you please clarify?

Thanks,
Anoop
