| Fast Recovery for EVPN Designated Forwarder Election |
|
|
The Ethernet Virtual Private Network (EVPN) solution provides Designated Forwarder (DF) election procedures for multihomed Ethernet Segments. These procedures have been enhanced further by applying Highest Random Weight (HRW) algorithm for Designated Forwarder election in order 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 Section 2.1 of [RFC8584] 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 between the recovered node and each of the other nodes in the multihoming group. |
