Intersting. I looked up the command, and then checked around CCO fo more info - because it apparently does not work on my routers. The route does not show up in the ospf database, nor is it forwarded through ospf. I tried this on two differnt routers after taking a literal reading of the command. R3------OSPF------R1---------BGP-------eBGP_domain |---------iBGP-------| I tried it both ways - on R3, and on R1. In neither case does the route in question appear in the ospf database, indicating to me that my humble 25xx routers do not seem to recognize this process. Maybe this is permitted only on the big boys? Maybe I need a different IOS? The routers in question or doing, I believe IP Plus, 12.1.5T10 and 12.2.12a. the later router has to be reloaded quite a lot. It is very flaky. The "book" answer is to add the route to ospf using a network statement. Doing that, it works fine. One of the current crop of Cisco ASET labs. Not a very well written lab IMHO. It's the kind of lab that turns you into a proctor pest. thanks. > > To allow the redistribution of internal Border Gateway Protocol (iBGP) > routes into an Interior Gateway Protocol (IGP) such as Intermediate > System-to-Intermediate System (IS-IS) or Open Shortest Path First > (OSPF), use the bgp redistribute-internal command in address family > configuration mode.
