[bess] MAC Move events between different ES in the same EVPN PE

[Alexander Vainshtein <[e-mail]>]

Hi all,
I am asking for clarification on the following issue related to Section 15 of 7432bis<https://datatracker.ietf.org/doc/html/draft-ietf-bess-rfc7432bis-10#section-15>.

Suppose that an EVPN PE that supports MAC learning from the data plane is attached to two different customer sites with at least one of the PE-CE links being part of a MH ES (in any MH mode).

Suppose further that the DP that has previously locally learned a certain MAC address from one of its PE-CE links and has advertised an appropriate RT-2 for it locally learns the same MAC address from another of these links so that now it has to advertise it with the new ESI value in the NLRI of RT-2?

Is such a situation considered as a locally detected MAC Move event for the purpose of Section 15 of 7432bis?
Specifically, should it result in starting the Duplicate MAC Detection timer and starting count of these events as described in Section 15.1 of 7432bis so that, if the number of these events detected while the timer is running exceeds the limit, this would result in declaring MAC address in question (and suppressing further advertisement of RT-2 for this MAC address)?

Your timely feedback would be highly appreciated.

Regards, and lots of thanks in advance,
Sasha
