for summary networks.

Configuring OSPF route redistribution

On a router running OSPF and other routing protocols, you can configure OSPF to redistribute static
routes, direct routes, or routes from other protocols, such as RIP, IS-IS, and BGP. OSPF advertises
the routes in Type-5 LSAs or Type-7 LSAs. In addition, you can configure OSPF to filter redistributed
routes so that OSPF advertises only permitted routes.
IMPORTANT:
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.
Redistributing routes from another routing protocol
Step
1. Enter system view.
