Are you referring to the Ethernet MAC addresses that the VTEP probably 
has on its underlay physical network?  I can see why those would be good 
candidates to use on the management VNI.  What I do not see is why we 
want to require it?  Using those would seem to complicate configuring 
BFD, since as far as I know those addresses are not known to remote VTEPs.

Yours,
Joel
