I have a border router R1. I wish to forward all incoming traffic coming from AS 200 via interface f0/0 for destination x.y.z.w to border router R2 with ip address a.b.c.d. However, if the incoming traffic for destination x.y.z.w comes from within the AS (100) I want to forward it to border router R3 with ip address g.h.i.j. How do I accomplish this?

suggest drawing a small diagram of how these connected, what is R1 AS number?

 

an example can be viewed here :

Can I see the topology ?
