Configure IBGP on Routers R1, R2, and R3 in your network (use AS 333):
■ Do not use any WAN IP interfaces for IBGP sessions, because your network is prone to failures across the Frame Relay cloud.
■ Configure R3 as route reflector.
■ Minimize IBGP configurations as much as possible.
■ Do not disable BGP synchronization.
■ As long as there is IP connectivity in your network, ensure that BGP is active in all routers.
■ Using the network command only, advertise all networks to route reflector R3.
■ Do not change the administrative distance on any interior routing protocol.
■ Make sure you have full BGP connectivity.
■ Be sure all routers have entries in their IP routing tables.
