Sean, Try adding "redistribute connected" to all 3 router configurations. This will ensure that all of your connected interfaces gets advertised. The problem sounds as though Router A does not have the 193.1.1.0/24 network in it's BGP table, thus that's why Router C can not ping Router A, because A does not know how to get to C. -Chuck ----- Original Message ----- From: "Sean C."
