Fabio, What do you mean by using BGP as the IGP? BGP is essentially an application, and like any other application on the network, it requires IP reachability between client and server (BGP peers) for it to function. Therefore, reachability needs to be setup be a protocol at layer 3 whether it be ISIS, OSPF or even statics.
