■
level-1-2: Imports the route into Level-1-2 routing table.
■
If the level for importing the route is not specified in the command, it defaults
to import the routes into Level-1 and Level-2, i.e. Level-1-2 routing table.
■
route-policy route-policy-name: Imports only the routes matching the specified
route-policy.
Description
Using the import-route command, you can configure IS-IS to filter the imported
routes. Using the undo import-route command, you can configure IS-IS not to
import the routing information of other protocols.
By default, IS-IS does not import routing information from any other protocols.
For IS-IS, the routes discovered by other routing protocols are processed as the
routes outside the routing domain. When importing the routes of other protocols,
you can specify the default cost for them. If OSPF routes are imported, you can
also specify the cost type for them.
When IS-IS imports routes, you can specify to import the routes to Level-1, Level-2
or Level-1-2.
IS-IS regards all the routes imported into the routing domain as the external
routes, which describe the way how to select the routes to the destination outside
the routing domain.
Example
Import a static route with cost 15.
[3Com-isis] import-route static cost 15
import-route isis Syntax
import-route isis level-2 into level-1 [acl acl-list ]
undo import-route isis level-2 into level-1 [ acl acl-list ]

Parameter
■
acl-list: ACL number. When configuring routing leak from Level-2 to Level-1,
only the routes that are permitted by ACL can be imported to Level-1 area if an
ACL has been specified.
Description
Using the import-route isis level-2 into level-1 command, you can enable routing
information in a Level-2 area to be imported to a Level-1 area. Using the undo
import-route isis level-2 into level-1 command, you can remove the function.
By default, routing information in a Level-2 area is not imported to a Level-1 area.
Example
Import routing information of a router from a Level-2 area to a Level-1 area.
