Eigrp over mpls
Us this widely done? When would one choose eigrp over bgp, for connections to service provider (l3 vpn)

Depends on the provider.
Some providers require BGP. Others are more flexible.

if you had a choice between both, which would you use?
How many routes will you be sending/receiving?
Is the routing protocol being run between two devices in the same AS or different AS's?

eigrp is cisco protocol. Because of it you may not use with all provider. I recommend that you may use OSPF over MPLS. it is working well and you are independence provider vendor equipment.

Right now we are running OSPF within each of our LANs. Our edge devices (Qwest MPLS) peer eBGP to provider. Our edge devices are also doing mutual redistribution
I was just wondering if it makes more sense to use OSPF to our provider instead, since we are relatively small
thanks

If you're not exchanging large numbers of routes, and your provider allows it, run any protocol you want.
Personally, I like OSPF for an IGP.

so if we're running multi area OSPF with a process ID of 1, our provider will form an adjaceny with a different process number?
if the 7 remote office is connected in same MPLS network, you may redistribute OSPF over MPLS. the most important case there you need check exchange routes quantity. If the 7 brunch connection stability is ok and not much load over them, OSPF will be better solution. BGP and eigrp give better solution over saturated networks.
Process ID's are locally significant only. One router never knows what process ID another is using.
infact you can collect all different area in one ospf process. But finally provider will redistribute over BGP. You will get just one peer in each brunch for OSPF.
Routers
A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.
