We started migrating from Frame Relay to MPLS this week. Decided to go with BGP routing during the turn-up, which sounded like it would be the easiest way. With traditional static routing, (I was told) our provider has to know about our network in order to get the packets to the right segment. With BGP, we manage our own routes and the provider's core doesn't have to be involved. Sounds perfect. I'm not a hardcore routing junkie, so it took a bit more effort than expected. But I did get it all figured out, and hope this will help someone else in the future.
