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??????
