Yep. I hate L2. It is a total nightmare. But, it is literally the only game in town. I blame the MEF for spreading propaganda that MetroEis the best solution for backhaul ... most people dont even think of L3 solutions.... all the telcos, cable-cos, and utilities in this space only do L2 to the cell site.... even though they all use the same Juniper and ALU gear that does L3 too ...
Curious, do you think this will last? Thought LTE is all-IP. Why is there a need for L2 other than raw bandwidth from Ethernet links?
They're talking backhaul between the node-b base-stations and the radio network controller... All the traffic from the handsets is encapsulated between those two points so it's link and network layer agnostic.
Thanks!
