Refer to the exhibit. Router 1 and router 2 are running IBGP, and router 2 and router 3 are running OSPF Area 0. Router 1 is advertising loopback interfaces Lo 0 and Lo 2, and router 2 is redistributing BGP into OSPF Area 0. Which configuration must an administrator apply so that router 2 uses a route map to redistribute only the internal route from Lo 2?
To ensure router 2 redistributes only the route from the loopback interface Lo 2 (22.22.22.22/32), configuration that includes the 'bgp redistribute-internal' command is essential. This command allows BGP to redistribute the routes learned internally. Additionally, the route map and prefix list must match the exact /32 prefix of Lo 2 (22.22.22.22/32), not a broader /24 subnet. Configuration A correctly includes these elements by using the correct prefix list and the 'bgp redistribute-internal' command, ensuring only the loopback address 22.22.22.22/32 is redistributed from BGP to OSPF.

Whenever you redistribute from BGP to something else, BGP will only release externally learned routes. Even if you try to match things specifically with a route-map or the “match internal external” commands, BGP simply will not let them be redistributed. In order to allow BGP to redistribute internal routes, you must explicitly command BGP to do it using the bgp redistribute internal command.
