Configuring Graceful Restart for Point-to-Multipoint LSPs
You can configure graceful restart on point-to-multipoint LSPs. Graceful restart allows a router undergoing a restart to inform its adjacent neighbors of its condition. The restarting router requests a grace period from the neighbor or peer, which can then cooperate with the restarting router. The restarting router can still forward MPLS traffic during the restart period; convergence in the network is not disrupted. The restart is not apparent to the rest of the network, and the restarting router is not removed from the network topology. RSVP graceful restart can be enabled on both transit routers and ingress routers.
To enable graceful restart on a router handling point-to-multipoint LSP traffic, include the graceful-restart statement:
You can include this statement at the following hierarchy levels:
- [edit routing-options]
- [edit logical-systems logical-system-name routing-options]
The graceful restart configuration for point-to-multipoint LSPs is identical to that of point-to-point LSPs. For more information on how to configure graceful restart, see Configuring RSVP Graceful Restart.
