This sets the maximum time this device will wait for a Graceful-Restart-capable neighbor to reconnect and restore its LDP session after that neighbor restarts, taking whichever is smaller between this local ceiling and the reconnect time the neighbor itself advertised. An admin tuning this would lower it on a network where restarts should recover quickly, to avoid holding stale forwarding state longer than necessary if a neighbor's restart actually fails outright. A value of 60000 (60 seconds) caps how long this device gives a restarting peer to come back before giving up and re-signaling normally.
