I am trying to simulate the internet by bringing in 3 different routers on point to points into a 3750G switch. While I can ping through the network, I am not getting any convergance of OSPF. We are using IOS version 12.2(53)se. Thanks.
From the configurations, between Router 1, 2, and 3, there is no common subnet. While router 2 and 3 have 206.36.206.x in common, I do not see any other common subnets between all three routers. If you are configuring so that even 3750 should participate in OSPF, you need to make sure that you are running IPServices image on the switch. Once you are running IP Services image, the configuration will be pretty much similar to the routers:
Router ospf 1
Network 188.8.131.52 0.0.0.3 area 0
Network 184.108.40.206 0.0.0.3 area 0
Network 220.127.116.11 0.0.0.3 area 0
Hope this helps.
