Question on dynamic routing and PIX VPN

Hi there,

I have a diagram online.

and a scenario I am going to type here.

Let say, I am a online backup service. I have by then an ftp server farm. In order to get the files in a secure way through the internet, my servers are behind a PIX and I need to use an IPSEC VPN to link the sites.

Let say I have 3 customers. Those customers are insisting the fact they wanna have a dedicated SDSL line on my location.

In front of my PIX, I have a router which I own. On this router, the routers of my 3 customers. Note, those routers are on 3 different ISP backbones.

What are the involved technologies to make sure a packet supposed to reach 195.238.4.17 (a VPN peer of my customer) will go through the Belgacom's link and not through AT&T.

Also. On the diagram, I've mentionned my infrastructure is on the COLT backbone. Well, I am not sure I need an ISP there. I can be my own ISP for this cross-over cable? Do I have to get in contact with an ISP to register a subnet?

Thank You,

Freddy
