The hello interval specifies how often an IS-IS interface sends hello messages to its IS-IS neighbors. The following task changes the hello interval for Level 1 packets to 20 for an IS-IS interface.
Procedure
-
Enter the
configure terminal command to access global configuration mode.
device# configure terminal
-
Enter the
interface ethernet
command and specify an interface.
device(config)# interface ethernet 1/2
-
Enter the
isis hello-interval
command with the
level-1 parameter, and specify a value, to change the hello interval for Level 1 packets for the interface.
device(conf-if-eth-1/2)# isis hello-interval level-1 20
Example
The following example changes the hello interval for Level 1 packets to 20 on a Loopback interface.
device# configure terminal
device(config)# interface ethernet 1/2
device(conf-if-eth-1/2)# isis hello-interval level-1 20
