**help w/ RIP network**

autoartist

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.

You only need to add the locally attached networks. I.o.w. remove the RIP network 163.1.0.0 from R3 and RIP network 10.0.0.0 from R1.


btw, try this one:

SPLIT HORIZON.. try to use a an ip-classless routing protocol such as RIP v2.
