Routing table doesn't have all routes I need

[C3PO]

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,

 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.

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)

Please keep us posted if it fixed the inconvenience.

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!
