3. Configure IS-IS route
summarization.

[ avoid-feedback | generate_null0_route | [ level-1 |
level-1-2 | level-2 | tag tag ] *
By default, route
summarization is not
configured.
Advertising a default route
IS-IS cannot redistribute a default route to its neighbors. This task enables IS-IS to advertise a default route
of 0.0.0.0/0 in an LSP to the same-level neighbors. Upon receiving the default route, the neighbors add
it into their routing table.
You can use a routing policy to generate the default route only when the routing policy is matched by a
route entry in the routing table.
To advertise a default route:

3. Advertise a default
route.

By default, IS-IS does not
advertise a default route.
Configuring IS-IS route redistribution
Perform this task to redistribute routes from other routing protocols into IS-IS. You can specify a cost for
redistributed routes and specify the maximum number of redistributed routes.
To configure IS-IS route redistribution from other routing protocols:

3. Redistribute routes
from another routing
protocol.
import-route protocol

allow-ibgp ] [ cost cost |
cost-type { external | internal }
| [ level-1 | level-1-2 | level-2 ]
| route-policy route-policy-name
| tag tag ] *
No route is redistributed by default.
By default, if no level is specified, this
command redistributes routes into the Level-2
routing table.
This command redistributes only active
routes. To display active routes, use the
display ip routing-table protocol command.
4. Configure the
maximum number of
redistributed Level
1/Level 2 IPv4 routes.
import-route limit number
Optional.
By default, the maximum number of
redistributed Level 1/Level 2 IPv4 routes is
500000.
