Nonstop bridging requires you to configure graceful Routing Engine switchover (GRES). To enable graceful Routing Engine switchover, include the graceful-switchover statement at the [edit chassis redundancy] hierarchy level:
- [edit chassis redundancy]
-
graceful-switchover;
By default, nonstop bridging is disabled. To enable nonstop bridging, include the nonstop-bridging statement at the [edit protocols layer2-control] hierarchy level:
- [edit protocols layer2-control]
-
nonstop-bridging;
To disable nonstop active routing, remove the nonstop-bridging statement from the [edit protocols layer2–control] hierarchy level.
