(I see it on both serials on one router, then on one serial of the other router ... something is up) I'm only to Chapter 6 of Todd Lammle, but I'm sure one of the earlier chapters mentioned that you set the clocking on only one side of the connection, not both.

What is your interface status? 4. Can you confirm the address scheme that you are using for your networks? We had a conversation about OSPF the other day, quite good, I think. Anyway, you can't get neighbors without the interfaces being in the same subnet. If you could draw a picture, it might help us and you to understand what is going on here. But, right now, I'm suspecting addressing.

amb1s1 wrote: » OK There are in the same network, so the network statement under OSPF should be as follow network 192.168.7.64 0.0.0.31 area 0 and take the network statement that you had no network 192.168.7.0 0.0.0.31 area 0

jwashington1981 wrote: » Do you want to keep one routing protocol on one side of the network and the other routing protocol on the other side of the network? If that is the case, then you have the option of performing redistribution on your router for both protocols. What that does is if you have a RIP update coming from one side of that router that you want to go to the other side, it will convert it to an OSPF route, and vice versa.
