I have remote sites connected by full T1 p-t-p links. There is no routing, all traffic is bridged. The entire network is one flat private-IP space. I have full communications between workstations at all sites: ping wkst to wkst works fine.
Problem: cannot ping ethernet interface addresses of remote routers. Also can't ping IP addresses on their serial interfaces.
One remote site is connected via a frame relay circuit, again only passing bridged traffic. I can ping that ethernet interface, but not the IP on its serial interface.
Without knowing what your network & addressing scheme is I can only speculate. Make sure you have a default route in each router pointing back to the main site. Use the 'ip default-route' command in global config.
As noted, network is one network number, 254 hosts possible, private IP range, no routing enabled, all bridged, one bridge-group. As I understand it, 'ip default-route' would be for routing off-net. This is one and the same net.
Your right, ip default-route wont be needed since your all on the same subnet. I'd try clearing your arp-cache with 'clear arp-cache' on both routers and see if that does it. Aside from that, I cant think of anything obious.
Thanks for the idea. In this case, they're HDLC PTP links, no frame. On the one frame circuit I noted, I do have those statements you mentioned and I CAN ping that e0/0 interface. I was hoping to find something similar for a bridged environment.
Separately, I had been working on speeding up the flooding of UDP packets. When I turned on ' IP forward-protocol spanning-tree any-local-broadcast' and 'ip forward-protocol turbo flooding', I was able to hit the remote site.
