Hi WG,
We have submmitted
https://datatracker.ietf.org/doc/draft-chen-bess-evpn-wtr-on-fast-df-recovery/.
In this draft, the SCT-EC is extended to the A-D per EVI routes, so that the
ingress PEs can perform the revertive FRR switching based on the time specified
by the SCT-EC for the non-adjacent ESes that support the fast DF recovery. Any
comments are welcome.
Best Regards,
Ran

Abstract:
The non-DF of a Single-Active Ethernet Segment (SA-ES) can filter
both unicast traffic and BUM traffic. In such case, when a specific
Single-Active ES performs fast DF recovery, the corresponding
revertive FRR switching should be performed on the ingress PEs that
are not adjacent to this ES. This revertive FRR switching needs to
be performed immediately after the A-D per EVI route with the "P=1"
is received from the new DF node. In other words, the revertive FRR
switching cannot perform the WTR procedures, otherwise unicast
traffic will be dropped on the new NDF node during the WTR.
In this draft, the SCT-EC is extended to the A-D per EVI routes, so
that the ingress PEs can perform the revertive FRR switching based on
the time specified by the SCT-EC for the non-adjacent ESes that
support the fast DF recovery.
