Packet tracer activity

Had a quick peek at it, router 4 has a wrong serial ip address, you used 172.20.7.1 while the middle router uses 172.20.8.2.

You also forgot to set a default gateway in the pc

So changing the serial interface 0/1/0 address on router 4 to 172.20.8.1
And giving PC-3 a default gateway in its ipconfig (172.20.9.2)
Should solve your problem

Sorry haven't got any place to upload the working file besides megaupload or something. But this should be a piece of cake.

Thanks for the answer. I've correct the gateway option.

I've this another proble, I check all the conditions for use RIP on this small network but the routers aren't routing.

What's going on?

Thank you

I've solve. The serial connector wasn't in the right place xD

I will modofied this file trying to add another network. I've configured the new RIP entry in graphic mode but when i check the routin gtable the new entry doesn't appear. I check all the conditions for use RIP on this small network but the routers aren't routing.

jeliament,

Could you post a link to your modified .pkt file so that we have a look. You can upload here: www.downloadtaxi.com

Well.....friend I have a solution for you. You can use 255.255.0.0 that means 172.20.x.x /16. But theres a problem with routers. You can not give same network on both interfaces. What you have to do is...put 172.20.x.x on 1 interface and 172.30.x.x on other side, and so on. This way you wont get overlap problem. And don't forget to put clock rates on DCE side.
