Changing the hello multiplier for an IS-IS interface

  1. Enter the configure terminal command to access global configuration mode.
    device# configure terminal
  2. Enter the interface ethernet command and specify an interface.
    device(config)# interface ethernet 1/2
    
  3. Enter the isis hello-mulitplier command with the level-2 parameter, and specify a value, to change the hello multiplier for Level 2 packets for the interface.
    device(conf-if-eth-1/2)# isis hello-mulitplier level-2 20
    

The following example changes the hello multiplier to 20 for Level 2 packets for an Ethernet interface.

device# configure terminal
device(config)# interface ethernet 1/2
device(conf-if-eth-1/2)# isis hello-mulitplier level-2 20
