Hello,

This question is not strictly related to this draft, but to VPWS in
general and may sound naive.
So *please* pardon me.

Shouldn't the port on the remote PE be turned down when its
equivalents on local PEs do the same?

This is something you can find on L2VPN VPWS signaled by LDP.
When local AC goes down the event is signaled via LDP to the other end
which in turn soft-shut the port.

I wonder if the same behavior could be replicated by EVPN VPWS.
In that case remote PE(s) would have to react to BGP prefix withdrawals.

Thank you

Regards
