I don't see your networks. After you type router rip you provide the ip address of each of your interfaces that are connected to other networks.

After you type: show run

there sould be a section for networks.

MasterLion

did you issue the no shutdown command :

and the network is not entered from what i can see after rip is enabled.

router2501a

E0 IP address 197.2.2.1
S0 IP address 1972.2.2

Host A
Ip address 197.2.2.3

router2501b

E0 ip address 197.2.3.1
S0 ip address 197.2.3.2

Host B
Ip address 197.2.3.3

Your problem is pretty simple and it's all in your addressing of the router interfaces. You assigned an IP address on the Ethernet and Serial interfaces that are on the same segment (assuming a 24 bit mask). You did this on both routers. I'm assuming that you want to connect RouterA to RouterB via S0, if you do you will have an addressing problem again as both Serial interfaces are on different segments (RouterA is 197.2.2.2/24, RouterB is 197.2.3.2/24).

Based on the above information, Host A and Host B should only be able to ping their own IP address and their corresponding router's Ethernet interface.

You have RIP running but you didn't advertise a network. You also have a static route pointing to an address that is unreachable by virtue of the addressing issue described above. As a general rule you should try not to mix static routes with dynamic routes without having a specific need and understanding the issues the they may create.
