2)  If both the maximum and initial intervals are specified: 

z 

IS-IS waits the initial interval before generating the first LSP.  

z 

If the network topology is unstable, that is, triggers occur at intervals shorter than the maximum 

interval, IS-IS waits the maximum interval before generating the first LSP until the network topology 

is stable.  

3)  If the maximum, initial, and second wait intervals are specified: 

z 

IS-IS waits the initial interval before generating the first LSP. 

z 

If the network topology is unstable, that is, triggers occur at intervals shorter than the maximum 

interval,, IS-IS waits the second-wait-interval before generating the second LSP and penalty is 

applied on the wait interval before generating the next LSP. That is, for each subsequent trigger, 

the wait interval before generating the LSP will be two times the previous wait interval until the 

maximum interval is reached.  

z 

After the network topology is stable; that is, triggers occur at intervals greater than the maximum 

interval, the wait interval before generating LSPs is restored to the initial interval.  

# Set the maximum, initial, and second wait intervals to 10 seconds, 100 milliseconds and 200 

milliseconds respectively.

2: System level 

seconds: Specifies the LSP maximum aging time in seconds, ranging from 1 to 65535.  

Use the timer lsp-max-age command to set the LSP maximum age in the LSDB.  

Use the undo timer lsp-max-age command to restore the default.  

The default LSP maximum age is 1200 seconds.
