Rip Challenge Problem

By Shs_Bulldog ·
Got a weird one for you. We have a network with about 10 routers. One at every school location. They all connect to one main router. We are using RND Routers. We have public 150.176.158.0 ips and private 172.21.0.0 ips on every router. For some reason, rip is putting in a route to 172.21.0.0 and saying that its next hop is a NT server connnected into another port on that router. It really slows it down cause it goes to that server then bounces back. Any idea why RIP would thing that my server is the next hop??????

For only ten routers, I really think I would use static routes, but that's another issue.

Somehow, RIP has defined the default route as being the address of your NT server. I think I would be looking to make sure every subnet has a unique address. From your question, it would appear that within your network, there may be duplicate IP addresses across your subnets. If so, that's the problem.

Have to disagree on the static routing entries, Paul.. But I hope these things are using RIP 2.

If there's routes pointing to an NT server, this NT server must be dual-homed, and/or have IP Forwarding enabled. Disable this. This should also stop it's inclusion in the RIP routing processes.

I'm thinking you're on some sort of frame network or something like that? If it is frame, you shouldn't use public addresses on them at all. Just use private all the way across and make a special subnet for the ports that touch the frame network. Then make different subnets for each of the schools.
You can use from 172.1.0.0 to 172.31.0.0 for a Class B network if you needed it.
Just make SiteA 172.1.0.0 mask 255.255.0.0. SiteB 172.2.0.0 mask 255.255.0.0. And so on. That'll give you plenty of addresses for each site.
Then each router will need to have only the Network in the RIP protocol which is at that site.

I know this involves alot of renumbering, but it's the best way I can discern to fix the problem.
