Currently I have two offices, one in London one in Jersey.
We are currently connected via a two 2mb leased PVC from our ISP. We do NOT use any VPN's currently.
We are putting in a third office in Jersey for DR purposes, which will be connected via a 10MB leased line.
Now... here come the problem.. I have no control over the router which does our PVC to our ISP at either end. Nice. Plus my boss wants to use meshed VPN's between all our offices as automatic backup to the PVC/leased lines. Lastly we use PIX firewalls... which we will need to use for the VPN's.
Enclosed is a network diagram of the solution...
Now, I have several questions...
1. Which routing protocol do I use?
2. How the hell do I tell the routing protocol to use the firewall if it can't get to the destination?
3. How should I configure the various areas?
My initial thoughts were that I should use OSPF over a GRE tunnel between the routers in London and Jersey over the clean PVC, with a higher cost static route to the firewall.
