I don't know much about ospf and I am having a problem. I have configured it in a redundant fashion with two routers at one site and two routers at another site. The problem is the routing table shows two entries for the same network to two different routers but I don't know how to make it select one.
For instance if you look at pri-2811 it has two entries to 10.101.102.0 but it goes to both 172.16.21.3 and 172.16.21.4 but I need it to use 172.16.21.3. I did some reading and applied a cost but that removed the routes all together but I figure I was on the right track. Any help would be greatly appreciated. Configs are attached.
