Parameters
protocol: Source routing protocol that can be imported, including direct, static, rip,
bgp, ospf, ospf-ase, and ospf-nssa.
allow-ibgp: Allows the redistribution of IBGP routes when redistributing routes from
BGP.
value: Cost of the imported route, in the range of 0 to 63.
type: Specifies the type of the routing cost. If it is internal, then it is a route within an
area; if it is external, it is a route between areas. The type is internal by default.
level-1: Specifies to import routes to Level-1 routing table.
level-2: Specifies to import routes to Level-2 routing table. If no level is specified, the
routes are imported to level-2 routing table by default.
level-1-2: Specifies to import routes to Level-1 and level-2 routing tables.
route-policy route-policy-name: Specifies to import only those routes satisfying the
matching condition of the designated route-policy. The route-policy-name argument is a
string containing 1 to 19 characters.
Description
Use the import-route command to enable IS-IS to filter the imported routes.
Use the undo import-route command to disable IS-IS from importing other protocols'
routing information.
IS-IS does not import other protocols’ routing information by default.
IS-IS takes all the routes imported to the routing domain as external routes, which
describe how to select a route to a destination outside of the routing domain.
Note that:
z The import-route bgp command redistributes EBGP routes only.
z The import-route bgp allow-ibgp command redistributes both EBGP and IBGP
routes.
