Having Packet Tracer issues

[BigWils93]

Hi all, I am in need of help. It is the easter break here in the UK and i have no lecturers to ask a question to so this forum is my only hope. I have a packet tracer file that i need to get working with ppp. I have done all the commands for ppp and it still continues not to work. I think i missed something out in the configuration but for the life of me, i cannot think of what i have missed out. Can anyone help me shed a light on why it will not work. 

The topology looks like this and i have made the packet tracer file available on dropbox if anyone wants to have a look at it.

Hey

If you post the config files without being in PT a lot more people will check it , like myself a lot of users here may not use PT so it will narrow down who is actually able to help you. If there just text files everyone can have a look for you , I can see your topology but I cant open the configs unless I install PKT

What is the problem exactly?

Only thing I found was that R3 did not have CDP enabled. 

It seems like all the PPP connection is forming as it should, with authentication. 

All the routers can ping their immediate neighbors, not further then that because there is no static routing nor routing protocols.

I hope I posted to right topic, it's very difficult here. Like no ones got the time to answer anyone :(

I would love to look at that file, but I am having problems saving or retrieving files, because of the changes Dropbox have made to their API.

My understanding is that they have updated their "API 1" with a new "API 2" and the way of working on my files while mobile, is for Cisco Mobile PT is to implement the new "API".

Are you still able to retrieve your files from "Dropbox"?
