Configuring LDP GR helper

By default LDP GR is disabled. You can globally enable it. When LDP GR enabled, the router waits until it receives an LDP Initialization message from its neighbor to know whether it must delete its states or start the LDP GR recovery procedure. Also, LDP GR is applicable to all LDP sessions regardless of the adjacency type that exists between the neighbors.

Note: The following command only takes effect on newly created sessions. For existing sessions, it is required that the sessions be restarted for the new configuration to take effect.
