Thanks so much for the quick response. After reading your reassurance that if it's up it should respond to pings I scrutinized my configs and discovered that their were some inconsistencies. I had put in some access lists to try to solve the problem Once I removed these entries, all interfaces are responding to pings across the links.
However, I still am unable to ping from R1 to a node that exists on a subnet of R2.
Do I need an access list or some type of translation to allow any traffic flowing from R1 to be allowed to traverse the link to R2 and to nodes it services?
I guess my learning style is to receive a point in the right direction so I that I can then research how to do it, so I will retain the knowledge once I am successful.

Hello all, I am trying to set up my CCNA lab environment, and I have everything working well, including the crossover connections between my three 1841 routers (all interfaces are up, and line protocols are all up)
In regards to those connections, via serial WIC-1DSU-T1-V2 WAN Interface Cards, I am not able to ping any of those specific interfaces IP addresses from the router they are on, nor am I able to ping from one node on Network 1 (Router1) across to Network2 (Router2).
Am I missing something like OSPF, or some other protocol to get this last step to work?
Any help would be appreciated!
