Thanks again for all of the replies on and off list. As I stated earlier, I didn't not think IGP was the protocol of choice for running to customers, i've just been to many different houses that do actually do this. 99% of all of our customer CPE is not managed by the customer, so that leaves it up to me to decide what to run to them. The only issue with using ebgp is getting enough of my staff that actually understand bgp to the point where they can deploy it themselves without having to get me involved on every install. I think I can make this pretty cookie-cutter config to start off and then work from there. We are moving to a new NOC so this network will get a fresh start (new 7513-sup720, few m10i's, and a dozen or so 7200vxr's). So my deployment strategy will be ebgp with multihmed customers. I just had to poke the fire so I had some ammo for upper management when they ask why I decide to go ebgp. And yes Philip, I actually have many of those presentations saved on my drive as they were all for not ;) Once again, thanks all for the replies.

The I in IGP stands for "interior" - which means "inside" your network, which does not mean "outside" your network. For the latter, we have BGP - if BGP for some reason seems too hard, check out the NANOG tutorials on the subject. Good luck! philip --
