Context config>router>ldp>graceful-restart
Description This command configures the neighbor liveness time, which is the time (in seconds) that the
LSR is willing to retain its MPLS forwarding state. The time should be long enough to allow
the neighboring LSRs to resynchronize all the LSPs in a graceful manner, without creating
congestion in the LDP control plane.
The no form of the command returns the default value.
Default 120
Parameters interval — specifies the length of time, in seconds
