Hi Authors,

I haven’t seen a reply to this message from almost a month ago, trying again. 
Even if you are still debating the answer amongst yourselves, it would be 
comforting to me to receive a reply to the effect of “we’re still thinking 
about this and will get back to you by $date”.

Thanks,

—John

Hi Authors,

I just went through draft-ietf-bess-evpn-inter-subnet-forwarding to look for 
answers to two questions:

1. Can a router advertise multiple different Router’s MAC values? If yes, what 
is the receiver supposed to do?
2. Assuming the answer to question 1 is “no”, what is the receiver supposed to 
do if it receives multiple Router’s MAC Extended Communities (with different 
values) anyway, for example due to a bug or configuration error? This is a very 
real possibility since many BGP implementations allow policy to produce 
arbitrary communities.

Thanks,

—John
