I prefer MX204 over the ACX5048. The ACX5048 can’t add L3 interface to an mpls layer 2 type of service. There are other limitations to the ACX5048 that cause me to want to possibly replace them with MX204’s. But in defense of the ACX5048, we have gotten some good mileage (a few years now) of good resi/busi bb over vrf’s and also carrier ethernet for businesses and lots of cell backhaul… so they are good for that. I’ve heard the ACX5448 was even better.
I’m looking at the MX240 for the SCB3E MPC10E hefty with 100 gig ports -Aaron
