Configuring IS-IS route summarization
This task allows you to configure a summary route so routes falling into the network range of the summary
route are summarized into one route for advertisement. Doing so can reduce the size of routing tables, as
well as the scale of LSP and LSDB. Both IS-IS routes and redistributed routes can be summarized.
The router summarizes only the routes in the locally generated LSPs. The cost of the summary route is the
lowest one among the costs of summarized routes.

route
summarization.

tag | [ level-1 | level-1-2 | level-2 ] ] *
By default, no route summarization
is configured.
Advertising a default route
A router running IS-IS cannot redistribute any default routes or advertise a default route to neighbors. Use
the following commands to advertise a default route of 0.0.0.0/0 to the same level neighbors.
