This caps how long this device will hold onto stale label mappings received from a restarting neighbor before deleting them if that neighbor doesn't refresh them in time, taking the smaller of this local value and the neighbor's own advertised Recovery Time. Unlike the reconnect-time and recovery-time objects, this setting explicitly does not get advertised to peers; it's purely a local safety ceiling the device enforces on itself. An admin worried about stale MPLS forwarding entries lingering too long after a failed peer restart would lower this value to force quicker cleanup of unrefreshed bindings.
