Changing the LSP interval and retransmit interval

  1. Enter the configure terminal command to access global configuration mode.
    device# configure terminal
  2. Enter the router isis command to enter IS-IS router configuration mode and enable IS-IS on the device.
    device(config)# router isis
    
  3. Enter the lsp-interval 45 command and specify a value to change the LSP interval from the default of 33 milliseconds.
    device(config-isis-router)# lsp-interval 42
    
  4. Enter the retransmit-interval command and specify a value to change the retransmission interval from the default of 5 seconds.
    device(config-isis-router)# retransmit-interval 10
    

Example

The following example changes the LSP interval to 45 milliseconds and changes the retransmission interval to 10 milliseconds.

device# configure terminal
device(config)# router isis
device(config-isis-router)# lsp-interval 42
device(config-isis-router)# retransmit-interval 10
