Background: Router A and B are connected via a common ethernet segment 1. Router A uses 10.10.10.1/30, and Router B uses 10.10.10.2/30. Router B also has another subnet configured for ethernet segment 1; 172.16.16.0/24. When I setup a situation like the above, with Router B advertising the 172.16.16.0/24 to router A, router A sees a next hop of 10.10.10.2. This is not good since packets from A going to the 172.16.16 subnet get sent to Router B, which then ARPs the desitnation, instead of just being ARPed by router A. I don't want to turn on ICMP redirects on B since they're insecure and ugly. I've also made sure I'm not using next-hop self. Is there a way to make this work? Ralph Doncaster principal, IStop.com
