I have network on picture and can't ping hosts each other. I've set RIP. Topology and output of "show ip route" are in attachment. I think that problem is in addresses I've set on serial links between routers, because when I change that IP addresses to some other with /24 mask, routing tables have more RIP routes and all ping commands work. But I don't understand why. I'm trying to have only 2 host addresses on point-to-point links and not to use unnubered option.
What is wrong?
Thank you!

Hi
Since you are using RIP version 1 the subnetted subnets will not be able to communicate, the point to point networks (/30) are not taken in account, so you must add these commands under the RIP process:
router rip
version 2
no auto-summary
RIP version 1 is no longer used, but if you have to use version 1 I recommend use other subnet /24 for the point to point between the routers and for the LAN (/28)

Hi,
Add the topology again please, it´s not possible to see it. And also, please attach the router config in txt files. It is impossible to analyse this in this format.
-If I helped you somehow, please, rate it as useful.-

Now it works! :)
Adding "version 2" on routers solved problem.
"no auto-summary" is also helpful. I'm going to read more about it.
@Julio E. Moisa, thank you very much!
