Use the undo summary command to remove a summary route.  

No summarization is configured by default. 

If no level is specified, only the level-2 routes will be summarized by default.  

You can summarize multiple contiguous networks into a single network to reduce the size of the routing 

table, as well as that of LSP and LSDB generated by the router. It is allowed to summarize native IS-IS 

routes and redistributed routes. After summarization, the cost of the summary route is the smallest cost 

of those summarized routes.  

Note that the router summarizes only routes in local LSPs. 

# Configure a summary route of 202.0.0.0/8.

maximum-interval: Maximum wait interval in seconds for generating IS-IS LSPs, in the range 1 to 120. 

initial-interval: Initial wait interval in milliseconds before generating the first IS-IS LSP, in the range 10 to 

60000. The default is 0. 

second-wait-interval: Wait interval in milliseconds before generating the second LSP, in the range 10 to 

60000. The default is 0. 

level-1: Applies the intervals to Level-1.  

level-2: Applies the intervals to Level-2 .If no level is specified, the specified intervals apply to both 

Level-1 and Level-2. 

Use the timer lsp-generation command to specify the wait interval before generating IS-IS LSPs.  

Use the undo timer lsp-generation command to restore the default.  

By default, the wait interval before LSP generation is 2 seconds. 

Note that: 

1)  If only the maximum interval is specified, IS-IS waits the maximum interval before generating an 

LSP.
