protocol process (rpd) on both Routing Engines. In addition, nonstop active routing
preserves TCP connections maintained in the kernel.
Graceful restart is configured—Graceful restart provides extensions to routing protocols
so that neighboring helper routers restore routing information to a restarting router.
These extensions signal neighboring routers about the graceful restart and prevent
the neighbors from reacting to the router restart and from propagating the change in
state to the network during the graceful restart period. Neighbors provide the routing
information that enables the restarting router to stop and restart routing protocols
without causing network reconvergence. Neighbors are required to support graceful
restart. The routing protocol process (rpd) restarts. A graceful restart interval is required.
For certain protocols, a significant change in the network can cause graceful restart to
stop.
