## Configure an ASBR Router

Routers that act as gateways (redistribution) between OSPF and other routing protocols (IGRP, EIGRP, RIP, BGP, static) or other instances of the OSPF routing process, are called ASBRs. An ASBR must be enabled for routes to be redistributed from other protocols.

This example configures router `10.0.0.1` to act as an ASBR.

1. Configure a router as an ASBR.

       SEFOS(config)# ipv6 router ospf
       SEFOS(config-router)# asbr router
       SEFOS(config-router)# end

2. Ensure that the router is configured as an ASBR.

       SEFOS# show ipv6 ospf
