Hi,

I see this document proposes 2 options for MVPN/EVPN.
One is using the destination address to carry the ID of an MVPN/EVPN, but this means that every BFR have to be aware of the MVPN/EVPN instance, introducing state of MVPN/EVPN service and forwarding overhead in transit BFR nodes.
The other is to use an IPv6 address after a BIER header and before the customer IP packet, however it proposes a new Proto value and new process in forwarding plane.
I think both of the options have obvious defects, and thus I do not support the adoption.

Thanks !
Fanghong Duan
