Subject: Micro BFD sessions over tagged ports

Hi,

Since micro sessions are essentially tracking the port (or link) status there needs clarity on what happens if the port is defined to have a dot1q (or a qinq) encapsulation?

I believe that similar to ethernet OAM packets, micro BFD packets should always be sent untagged even on tagged dot1q or qinq ports. This way, once the micro BFD session times out, we can remove that link from all LAGs that use this port.

We need a consensus on this and it has to get nailed down in the next version of the draft for inter-op purposes.

Cheers, Manav
