Rip Question

Ok Maybe someone could clear this up for me....

I have a lab with 3 routers say A,B and C. Each have a point to point connection. I also have a loopback set on each router to simulate an internal network. The networks between each link are 192.168.1.0/24 for A to B, 192.168.2.0/24 for b to c and 192.168.3.0/24 for c to a. The loopback for a is 192.168.4.1/24, b is 192.168.5.1/24 c is 192.168.6.1/24.

I have also configured rip on each router to advertise each network on there 2 serial interfaces which are the point to point connections. Now if i wanted to ping 192.168.5.1 (On

from router A should i be able to do so with this setup? or would i have to advertise the internal network in Rip using network 192.168.4.0 (on A) for example?

I know i can add a static route and it works with a ping but i thought that was the whole point of dynamic protocols - so you didnt have to rely on static routes etc?

Can anyone shed some light on this?

Cheers

You need to advertise the loopback interfaces into rip.

router rip
network 192.168.1.0
network 192.168.2.0
network 192.168.3.0
network 192.168.4.0
network 192.168.5.0

Would i have to advertise all the networks on every router or just the networks connected to that router?

Only on the router you created the network on then rip will advertise it to the other routers.

Remember, the network command only tells what interfaces to advertise the subnets on. So for example on Router A if you do the command:

router rip
network 192.168.4.0

This means send/receive RIP updates on this interface
