Multihomed BGP routers

We have two multihomed ebgp routers using the same AS number that advertise our routes into our carrier. The routers connect into the backbone using eigrp. Routes are only announced into BGP, eigrp is not redistributed into bgp.

Is there anyway to filter EBGP routes so the routes from the same AS number are not accepted into the routing table? We can't just filter out the route itself.

Re: Multihomed BGP routers

If you are trying to prevent one of your routers from learning BGP routes advertised by the other to your carrier, then it should happen by default. BGP updates received with the same AS# as that of the router itself will be dropped.
