Marc, Thanks a lot for review.

[SPK]Yes, since we did not propose any changes to inner MAC we did not mention about that. I think you are right we should mention that for clarity. > > outer-IP, udp, VxLAN-header, inner-Ethernet-header, inner-IP, udp, BFD > > if we talk about VxLAN RFC7348.

If e.g. your VTEP is a switch (TOR) then it would simply forward the > inner L2 frame on some L2 interface. [SPK] If inner VTEP is not L3 capable then BFD should not be established. BFD will be applicable to VTEP's which are L3 aware.
