I am still trying to keep up on the thead, but depending upon your end goal, you can redistribute or use the network command to originate exact matches to prefixes in your routing table.
If you don't want to have an exact match, there are other ways to get creative. You can use the aggregate address command for example. Also, in some versions of IOS, you can use an inject map if you want to advertise a more specific subset of routes, (rather than the aggregate), assuming that they are seen somewhere in BGP in your network, generally speaking. Think of an inject map almost like a way to un-aggregate or de-summarize your routes. Can you clarify your end goal? Thanks, Christianne (C.J.)

BGP only accepts the same prefix in the routing table? right?
