I apologize as this is kind of a "Out There" request. I'm setting up my first "service provider" type MPLS network consisting of several 6500s and ASRs. I've been looking around for a while now for a good IOS to load on the 6500s that will support a PE role (with 20-25 CEs on each initially and scale from there).

As I am a bit new to this design selection - does anyone have a recommendation of a good IOS to look at (Sup 720s w/ MSFC 3s)? It would be great if the IOS showed support for FWSMs as there are a few in the mix that need to be used.

Any help would be appreciated. My mind spins a little when looking at several "similar" IOS versions that appear to have differing features.
