Greg,



I am wondering why you are not using Ethernet-OAM over VXLAN rather than
encapsulating BFD in UDP/IP/Ethernet and then encapsulating it in VXLAN?



Thx

Shahram

Now with the correct OOAM-DT address

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
