Cisco router using RIP however no output from show ip route ip

Greetings, I built a basic topology (see attached picture) for three routers (c7200) in GNS3. For the IOS I'm using 12.4(4)T1.

I'm using RIPv2 to build routing tables for all routers, I can run the following commands ok from the East and West Router

east#show ip protocols
Routing Protocol is "rip"
  Outgoing update filter list for all interfaces is not set
  Incoming update filter list for all interfaces is not set
  Sending updates every 30 seconds, next due in 7 seconds
  Invalid after 180 seconds, hold down 180, flushed after 240
  Redistributing: rip
  Default version control: send version 2, receive version 2
    Interface             Send  Recv  Triggered RIP  Key-chain
    Serial1/0             2     2
  Automatic network summarization is not in effect
  Maximum path: 4
  Routing for Networks:
    10.0.0.0
  Routing Information Sources:
    Gateway         Distance      Last Update
    10.0.1.1             120      00:00:16
  Distance: (default is 120)

east#show ip route rip
     10.0.0.0/24 is subnetted, 2 subnets
R       10.0.0.0 [120/1] via 10.0.1.1, 00:00:12, Serial1/0

However from my Central Router, I am unable to get any output when I run the same command that runs ok on the other two routers. Even though they are all using the same IOS.

show ip route rip

I don't understand why?

What is the IP address of the interfaces? also do all three routers have ripv2 enabled? Need more information please.

You can't see RIP because it doesn't need any RIP routes. The East and West routers are directly connected. Directly connected routers always beat RIP routes (administrative distance). Add a 4th router into the mix and you will start seeing RIP routes.

Very true I didn't even think about that.

The East and West routers are connected via Central Router.

Yes. They are.

Can you post the running-configs for each router?

The central Router will not display the Rip routes for East and West because it is directly connected to East and West.

Do a "show ip route" command and you will see East and West in the routing table with a "c" for directly connected.

You could also put loopbacks on the East and West routers, and advertise them into RIP. You should see those routes in RIP, and the actual interfaces as connected routes.
