**help w/ RIP network**

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



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

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

Routing for Networks:

results from "show ip proto" cmd.

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

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

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

Gateway of last resort is not set

R [120/1] via, 00:00:15, Ethernet0 is subnetted, 3 subnets
C is directly connected, Serial1
R [120/1] via, 00:00:15, Ethernet0
C is directly connected, Ethernet0 is subnetted, 1 subnets
C 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 network and one is in the network)
-I cannot ping R1

R1 has no route to 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 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.
