graceful-restart timer neighbor-liveness

Description
Use the graceful-restart timer neighbor-liveness command to set the LDP neighbor liveness time.
Use the undo graceful-restart timer neighbor-liveness command to restore the default.
By default, the LDP neighbor liveness time is 120 seconds.
Modifying the LDP neighbor liveness time will cause all LDP sessions and all LSPs based on the sessions to
be removed and then reestablished.
For LDP sessions with MD5 authentication configured, you need to give the LDP neighbor liveness time a
greater value so that the TCP connection can be reestablished.
