Hi,
I have the following network with RIP (v1) static routing. I have advertised the networks and pinging works for each end device. Now if I disconnect the connection between R2 and R3, should the PC 172.168.20.10 still be able to ping PC 172.168.30.10 ?
Currently it's not pinging if I disconnect the connection between R2 and R3, I'm assuming that it should ping as the packet should travel through R1, since all the routes are advertised.
R1#sh ip route
172.168.0.0/24 is subnetted, 3 subnets
C 172.168.10.0 is directly connected, FastEthernet0/0
S 172.168.20.0 [1/0] via 192.168.10.2
S 172.168.30.0 [1/0] via 192.168.30.2
C 192.168.10.0/24 is directly connected, Serial0/0/0
R 192.168.20.0/24 [120/1] via 192.168.10.2, 00:00:03, Serial0/0/0
[120/1] via 192.168.30.2, 00:00:01, Serial0/0/1
C 192.168.30.0/24 is directly connected, Serial0/0/1
R2#sh ip route
172.168.0.0/16 is variably subnetted, 3 subnets, 2 masks
C 172.168.0.0/16 is directly connected, FastEthernet0/0
S 172.168.10.0/24 [1/0] via 192.168.30.1
S 172.168.20.0/24 [1/0] via 192.168.20.1
R 192.168.10.0/24 [120/1] via 192.168.30.1, 00:00:12, Serial0/0/0
C 192.168.20.0/24 is directly connected, Serial0/0/1
C 192.168.30.0/24 is directly connected, Serial0/0/0
R3#sh ip route
172.168.0.0/16 is variably subnetted, 3 subnets, 2 masks
C 172.168.0.0/16 is directly connected, FastEthernet0/0
S 172.168.10.0/24 [1/0] via 192.168.10.1
S 172.168.30.0/24 [1/0] via 192.168.20.2
C 192.168.10.0/24 is directly connected, Serial0/0/0
C 192.168.20.0/24 is directly connected, Serial0/0/1
R 192.168.30.0/24 [120/1] via 192.168.10.1, 00:00:12, Serial0/0/0
Thank You

Hello,
RIPv1 converges relatively slow, so you will have to wait for a while for the routing tables to be updated. That said, is this a Packet Tracer lab ? If so (zip first) post the .pkt project file...

Hello
Disable auto-summerisation and change protocol version.
All routers
router rip
no auto-summary
version 2
test again.....

Thank you for the reply..
Can I know if what I'm trying to achieve (pinging between PC1 and PC2 after disconnecting betweenR2 and R3 with RIp v1) possible or it will need RIP v2 ?
Thank You

Hello
If you using VLSM which it looks like you are then ripv2 is required as it supports VLSM and classless routing as apposed to ripv1 that doesn't support these features and as such doesn't look at the subnet mask of the defined network you wish to advertise only at the major network its related connect interface it is attached to.
