• Type-2 external route
An intra-area route is a route in an OSPF area. An inter-area route is between any two OSPF areas. Both
of them are internal routes.
An external route is a route to a destination outside the OSPF AS.
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 routes.
Use the import-route bgp allow-ibgp command with care, because it redistributes both EBGP and IBGP
routes that might cause routing loops.
Only active routes can be redistributed. To view information about active routes, use the display ip
routing-table protocol command.
The undo import-route protocol all-processes command removes only the configuration made by the
import-route protocol all-processes command, instead of the configuration made by the import-route
protocol process-id command.
Examples
# Redistribute routes from RIP process 40 and specify the type, tag, and cost as 2, 33 and 50 for
redistributed routes.
