summarization
NOTE:
The summary route cost is the lowest one among the costs of summarized routes.
•
• The router summarizes only the routes in the locally generated LSPs.

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.
Follow these steps to advertise a default route:
To do...
Enter system view
Enter IS-IS view
Advertise a default route
NOTE:
The default route is only advertised to routers at the same level. You can use a routing policy to generate
the default route only when a local routing entry is matched by the policy.

Configuring IS-IS route redistribution

Redistributing large numbers of routes on a device may affect the performance of other devices in the
network. If this happens, you can configure a limit on the number of redistributed routes in order to limit
the number of routes to be advertised.
Follow these steps to configure IS-IS route redistribution from other routing protocols:
To do...
Enter system view
Enter IS-IS view
Use the command...
system-view
isis [ process-id ] [ vpn-instance
vpn-instance-name ]
summary ip-address { mask | mask-length }
[ avoid-feedback | generate_null0_route | tag
tag | [ level-1 | level-1-2 | level-2 ] ] *
Use the command...
system-view
isis [ process-id ] [ vpn-instance
vpn-instance-name ]
default-route-advertise [ route-policy
route-policy-name | [ level-1 | level-1-2 |
level-2 ] ] *
Use the command...
system-view
isis [ process-id ] [ vpn-instance
vpn-instance-name ]
