Option: Configuring VPLS Graceful Routing Engine Switchover

Graceful Routing Engine switchover (GRES) allows a routing platform with dual Routing Engines to switch over from a master Routing Engine to a backup Routing Engine without causing an interruption to packet forwarding. Graceful Routing Engine switchover is supported with VPLS, meaning that should the master Routing Engine go down, the router can switch to the backup Routing Engine without affecting VPLS traffic.

To configure graceful Routing Engine switchover, include the graceful-switchover statement at the [edit chassis redundancy] hierarchy level. To disable graceful Routing Engine switchover, remove the graceful-switchover statement at the [edit chassis redundancy] hierarchy level.



[edit]
chassis redundancy {
graceful-switchover;
}
