		If both systems are Backup (Lock), reset the lock status of either one of the systems
		or both systems.
		If both systems are Master, restart one of GSRP programs using the restart

		In other cases, temporary status transition is in progress. Wait for a while.

When detecting the reception timeout of GSRP Advertise in GSRP configuration causes unknown adjacency, isolate the cause according to the table below.
