By default, IS-IS does not
advertise a default route.
679BConfiguring 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:

362. Redistribute routes from
another routing protocol.

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.
363. 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.
680BConfiguring IS-IS route filtering
You can use an ACL, IP prefix list, or routing policy to filter routes calculated using the received LSPs and
routes redistributed from other routing protocols.
1461BFiltering routes calculated from received LSPs
IS-IS saves LSPs received from neighbors in the LSDB, uses the SPF algorithm to calculate the shortest path
tree with itself as the root, and installs the routes into the IS-IS routing table.
Perform this task to filter calculated routes. Only routes not filtered can be added into the IS-IS routing
table.
