Abstract:
The Ethernet Virtual Private Network (EVPN) solution in RFC 7432
provides Designated Forwarder (DF) election procedures for multihomed
Ethernet Segments. These procedures have been enhanced further by
applying the Highest Random Weight (HRW) algorithm for Designated
Forwarder election to avoid unnecessary DF status changes upon a
failure. This document improves these procedures by providing a fast
Designated Forwarder election upon recovery of the failed link or
node associated with the multihomed Ethernet Segment. This document
updates RFC 8584 by optionally introducing delays between some of the
events therein.
The solution is independent of the number of EVPN Instances (EVIs)
associated with that Ethernet Segment and it is performed via a
simple signaling in BGP between the recovered node and each of the
other nodes in the multihoming group.
