Ahmed,
I've been using tcl scripts to detect these types of problems within the
IGPs and backbone routers. The IE labs usually state that all networks must
be pingable, so I typically end up injecting defaults or using NAT. Sometime
the border routers end up being 3550's, so all you've got is
BGP_Next_Hop_Self, PBR and defaults. I think the end game is that you must
have all networks reachable by all devices. (And no statics!)
