Command Reference
import-route
Purpose Use the import-route command to configure IS-IS to filter the redistributed
routes.
Use the undo import-route command to configure IS-IS not to redistribute the
routing information of other protocols.
Syntax import-route protocol [ allow-ibgp ] [ cost value ] [ type { external |
internal } ] [ level-1 ] [ level-1-2 ] [ level-2 ] [ route-policy
route-policy-name ]
undo import-route protocol [ cost value ] [ type { external | internal
} ] [ level-1 ] [ level-1-2 ] [ level-2 ] [ route-policy
route-policy-name ]
Parameters protocol
Specifies source routing protocols which can be
redistributed, including direct, bgp, ospf, ospf-nssa ,
ospf-ase, rip and static at present.
allow-ibgp
Optional when the protocol argument is set to
BGP. Whereas the import-route bgp command
redistributes only EBGP routes, the import-route bgp
allow-ibgp command redistributes IBGP routes in
addition and as such, must be used with cautions.
cost value
Specifies the route cost of the redistributed route,
ranging from 0 to 63.
level-1
Redistributes the route into Level-1 routing table.
level-2
Redistributes the route into Level-2 routing table.
level-1-2
Redistributes the route into Level-1-2 routing table.
If the level for redistributing the route is not specified
in the command, it defaults to redistribute the routes
into Level-1 and Level-2, i.e. Level-1-2 routing table.
route-policy
route-policy-name
Redistributes only the routes matching the specified
route-policy.
Default By default, IS-IS does not redistribute routing information from any other protocols.
Example Redistribute a static route with cost 15.
[3Com -isis] import-route static cost 15
