Syntax
import-route protocol [ process-id | all-processes | allow-ibgp ] [ cost cost | [ cost cost | route-policy
route-policy-name | tag tag | type type ] *
undo import-route protocol [ process-id | all-processes ]
Default
OSPF does not redistribute AS-external routes from any other routing protocol.
Views
OSPF view
Predefined user roles
network-admin
Parameters
protocol: Redistributes routes from the specified protocol, which can be bgp, direct, isis, ospf, rip, or
static.
process-id: Specifies an process by its ID in the range of 1 to 65535. The default is 1. It is available only
when the protocol is rip, ospf, or isis.
all-processes: Redistributes routes from all the processes of the specified routing protocol. This keyword
takes effect only when the protocol is rip, ospf, or isis.
allow-ibgp: Allows redistribution of IBGP routes. It is available only when the protocol is bgp.
cost cost: Specifies a route cost in the range of 0 to 16777214. The default is 1.
route-policy route-policy-name: Uses the specified routing policy to filter redistributed routes. The
route-policy-name argument is a case-sensitive string of 1 to 63 characters.
tag tag: Specifies a tag for marking external LSAs, in the range of 0 to 4294967295. The default is 1.
type type: Specifies a cost type, 1 or 2. The default is 2.
Usage guidelines
This command redistributes routes destined for other ASs from another protocol. AS external routes
include the following types:
Type- 1 external route
Type-2 external route
A Type- 1 external route has high reliability. Its cost is comparable with the cost of OSPF internal routes.
The cost from an OSPF router to a Type- 1 external route's destination equals the cost from the router to the
ASBR plus the cost from the ASBR to the external route's destination.
A Type-2 external route has low credibility. OSPF considers the cost from the ASBR to the destination of
a Type-2 external route is much bigger than the cost from the ASBR to an OSPF internal router. The cost
from an internal router to a Type-2 external route's destination equals the cost from the ASBR to the Type-2
external route's destination.
The import-route command cannot redistribute default external routes.
The import-route bgp command redistributes only EBGP routes. Because the import-route bgp
allow-ibgp command redistributes both EBGP and IBGP routes and might cause routing loops, use it with
caution.
