To configure graceful restart globally for all MPLS-related protocols, include the

To disable graceful restart globally, include the

Because CCC and TCC rely on RSVP, you must modify these three protocols as a single
group.
To configure how long the router retains the state of its RSVP neighbors while they
undergo a graceful restart, include the
[edit protocols rsvp graceful-restart]
routers, so it should be based on the time required by the slowest RSVP neighbor to
recover.
To configure the delay between when the router discovers that a neighboring router has
gone down and when it declares the neighbor down, include the
maximum-helper-restart-time
hierarchy level. This value is applied to all neighboring routers, so it should be based on
the time required by the slowest RSVP neighbor to restart.
