Ralph, What you are asking for is dynamic routing protocol to be able to tell you how to do something locally scoped. This is why we have redirects on ethernets. But, since you must do this with BGP, try this... (I haven't) router bgp x neighbor 10.10.10.2 remote-as x neighbor 10.10.10.2 route-map foofoo in ! route-map foofoo permit 1 match ip address 1 set interface e1 ! access-list 1 permit 172.16.16.0 -chris

Is this what you're trying to do: route-map <foo> match <whatever> set ip next-hop <something>Not really, what I want is router A to learn that ther is no next hop IP- the subnet is on the local ethernet. -Ralph
