Ok, here's one for you... Our network is running on Cisco 1600, 2600 and 2800 routers. We have four campuses of several buildings, connectivity between buildings is provided via fiber optic switch between buildings at each campus. We have a location on the west side of town (192.168.49.x) connected via T1 thru a Cisco 1600 to our main 2800 at our data center. This is a very simple connection, and works flawlessly. Our other two remote networks are connected via wireless (Proxim Tsunami and Cisco bridges). As such, our main network (let's call it 192.168.99.x) has it's network segment carried into each building via the bridges. At the data room in each location, we have a cisco router which handles routing between the two networks (192.168.43.x and 192.168.46.x) and the main .99.x network. All of the three routers have an interface on the 192.168.99.x network, and either just route data, or handle some nat activity to pass traffic between networks. Here's where the problem comes in.
Our hardware / software vendor is telling us that we can't use IP Redirects anymore, since it is filling up the routing tables on their unix box. When we turn off IP Redirection, communications grinds to a halt between the two routers with interfaces on the 192.168.99.x network. The stores on the T1 connected network (192.168.49.x) continue to communicate with the Unix box just fine. If I'm understanding this right, IP redirection is required for two routers to talk on the same network to pass traffic from one to the other?
If there is a solution to pass routing between the routers with IP Redirection turned off on the 192.168.43.x, 192.168.46.x, and 192.168.99.x interfaces, that would make my day. I can offer whatever clarification is possible, if I'm not clear enough. I'm sure this is a simple answer that I just can't find, but it's a very urgent issue at the moment, so we're going 500 points. Thanks!!!
