At 0XFFFFFFFF , this router will suspend the IS-IS process for MaxAge + ZeroAgeLifetime seconds,best ccna training, so that the LSP corresponding to this router in the entire routing domain is deleted. The IS-IS process is then restarted and the LSP is sent starting with sequence number 1 . (In fact, this situation will not arise, because even generate a per LSP , but also to 136 years after the serial number can be from 1 to reach 0XFFFFFFFF .
