Specify the number of IS-IS hello packets a neighbor must miss before the router declares the adjacency
down.
Syntax
isis hello-multiplier multiplier [level-1 | level-2]
To return to the default values, use the no isis hello-multiplier
[multiplier] [level-1 | level-2] command.
Parameters
multiplier Specifies an integer that sets the multiplier for the hello
holding time. Never configure a hello-multiplier lower than
the default (3). The range is from 3 to 1000. The default is 3.
level-1 (OPTIONAL) Select this value to configure the hello
multiplier independently for Level 1 adjacencies. This value
