■ Interface view
Description ISIS protocol maintains the adjacency between the adjacent routers by sending and
receiving Hello messages. If the local router does not receive a Hello message from
the peer within an interval, it regards the neighbor unavailable. The interval is the ISIS
holddown time.
In ISIS, the holddown time can be regulated by configuring the number of invalid
Hello messages. That is, the local router regards its neighbor unavailable if it has not
received the specific number of Hello messages consecutively.
If you do not specify Level-1 or Level-2 in the command, the system applies the
number of invalid Hello messages to Level-1 and Level-2.
