Thanks Mark - As always, extremely helpful!

Very interesting - Im liking this as a solution! Ive had a look at the ME3600X (Are you using the ME-3600X-24TS? i.e. you dont require the "CX" version for L3 + L2 VPNs?), and you need Advanced Metro IP Access?

So in this scenario, we would replace the 4848's with ME3600X's, and all L3(VRF) config would be done on the 3600X's (Carrier AGG's would still terminate on the 3600X's)

Both 3600X's would be connected, plus have mesh to the P's? And run OSPF/MPLS and TE on these links?

I dont have access to pricing atm, but are the 3600X's a "lot" more expensive than 4948's?

Thanks again for your responses.
