Changing the LSP interval and retransmit interval

The LSP interval is the rate of transmission, in milliseconds, of the LSPs. The retransmit interval is the time, in seconds, the device waits before it retransmits LSPs. This task changes the LSP interval to 45 milliseconds and changes the retransmission interval to 10 milliseconds.

About this task

Procedure

  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
