Public DMVPN network.

I was thinking about a new project idea. I was thinking of setting up a dynamic multipoint VPN concentrator. Put a small LAN behind it with a couple of servers. Put the configuration instructions on a webpage for Juniper and Cisco devices. I was thinking to run BGP routing protocol over the interface as it scales reasonably well.

The important part here is I wanted to create a web form which requests the internal and external address ranges of anyones network. Once that person submits that information I will have a Peal script pull those messages from the web form, parse the information, insert the networks and IP addresses into a J-Script template and apply it to my Juniper SRX router automatically.

This project will enable Cisco and Juniper students to participate in the environment and create a public VPN network where p2p APPS and anything else can run over the network without having to worry about any prying eyes. I want to see how far this project will scale. I was even envisioning a time when other people with idle equipment can volunteer to become a secondary hub to take some of the load once my connection reaches 10 thousand or so tunnels. Because of the way DMVPN works. The tunnels between sites will open up as needed when a user from site A needs to talk to site B. This combined with using BGP as the routing protocol will mean that it will require very little bandwidth as traffic destined from site A to C will not transit site B if site B in this scenario is the hub.

Anyways if anyone out there is interested please leave a comment.

    Hi

    I would be interested in this if you’re still thinking about it.

    I mainly work with the Juniper SSG and SRX range of devices and would like to learn some more BGP stuff 🙂
