If RtrB is an iBGP peer of RtrA, it will never advertise a route to RtrA that it learned from RtrA or any other iBGP peer.
HTH, John >>> "Cebuano" 2/6/02 10:38:01 AM >>> As per CCO: BGP selects only one path as the best path. When the path is selected, BGP puts the selected path in its routing table and propagates the path to its neighbors. But... Step 3 - prefer the path with the largest local preference. Step 4 - If the local preferences are the same, prefer the path that was originated by BGP running on this router. So if RtrA originated 10.0.0.0, it advertises this to its IBGP peer RtrB with a default Local Preference = 100, now if RtrB is configured with a route-map that sets this incoming update's Local Preference to 250, this would result in RtrA installing in its route table "to get to 10.0.0.0 prefer taking the path that goes to RtrB"? So now RtrA propagates this info to RtrB? Please help make some sense of this.
