I have a situation that I'm not sure if it's a device issue or a Cisco issue. I have a Netgate appliance which creates a tunnel into our provider via cellular connection. This tunnel is always up. My router has a floating route to fall over to this appliance if the serial side is down. I get my default route from our provider via bgp.
This is what my router looks like:
*B 0.0.0.0 via 18.104.22.168
ip route 0.0.0.0 0.0.0.0 192.168.1.2 254 name Netgate
This works as intended, but I'm having weird issues sometimes with internal devices latching onto the Netgate as their route for only certain routes. For instance, we have all Cisco APs which have a redirect cache on them but no routing table. If I have a host at 192.168.30.50, the AP may find it like:
But the APs default gateway is 192.168.1.1 (my router). This is not just happening on APs though. It's happening on 3Com switches as well. I'm not sure how it's happening either. The serial side has never went down at this location. I could understand if the router had to fail over to this device and then traffic had to pass over it and kept it in cache at that point, but that's not the case. Is there something else I should be looking at on the router side? At this point, I think it's the Netgate that's causing my problem. Before I can get in touch with the provider, I wanted to make sure that it wasn't a configuration problem on my end because I'm sure that's what they'll focus on.
