Abstract:
The Designated Forwarder (DF) in (PBB-)EVPN networks is the PE
responsible for sending multicast, broadcast and unknown unicast
traffic to a multi-homed CE, on a given Ethernet Tag on a particular
Ethernet Segment (ES). The DF is selected based on the list of PEs
that advertise the Ethernet Segment Identifier (ESI) to the EVPN
network. While PE node or link failures trigger the DF re-election
for a given <ESI, EVI>, individual Attachment Circuit (AC) or MAC-VRF
failures do not trigger such DF re-election and the traffic may
therefore be permanently impacted, even though there is an
alternative path. This document improves the DF election algorithm so
that the AC status can influence the result of the election and this
type of "logical" failures can be protected too.
