**help w/ RIP network**

Hello,

I have a RIP setup that I couldn't get to work in the lab today.
Hopefully someone will help

Thanks


R1
R2
R3

R1 to R2 = serial, 163.1.0.0
R2 to R3 = FastEthernet, 10.0.0.0

R1, R2, R3 have "router rip, network 163.1.0.0, network 10.0.0.0"
Interfaces are up and up from "show interface" command on all Rs.
All three Rs have:

Routing for Networks:
163.1.0.0
10.0.0.0

results from "show ip proto" cmd.

R3 "sho ip route" results has (line of interest):
R 163.1.0.0/16 [120/1] via 10.10.10.12, 00:00:08, FastEthernet1/0

R2 "sho ip route" has (line of interest):
C 10.10.10.0 is directly connected, FastEthernet0

R1 "sho ip route" has (full results):

Gateway of last resort is not set

R 192.168.12.0/24 [120/1] via 163.1.23.203, 00:00:15, Ethernet0
163.1.0.0/25 is subnetted, 3 subnets
C 163.1.12.128 is directly connected, Serial1
R 163.1.13.128 [120/1] via 163.1.23.203, 00:00:15, Ethernet0
C 163.1.23.128 is directly connected, Ethernet0
172.16.0.0/22 is subnetted, 1 subnets
C 172.16.12.0 is directly connected, Serial0

You can probably see my problem already.

from R3:
-I can ping R2 on both sides (Fastethernet and serial i/f, one is in the
10.0.0.0 network and one is in the 163.1.0.0 network)
-I cannot ping R1

R1 has no route to 10.0.0.0 in the route table. I suspect that is the reason why I can't ping it (R1) from R3 and nor can I ping the 10.0.0.0 network from R1. R2 can ping just fine to both networks, ofcourse it has routes for both in the route table.

Am I suppose to add a gateway on R1? What is wrong?

Thanks for your help.
