Hi,
I would like to understand why there is a preference for L3 VPNs over L2 VPNs for the EPC backhaul networks? We can use both layer 2 and layer 3 VPNs for communication between the eNodeB and the MME or S-GW, so why is it that most providers prefer L3 over L2.
There are just more companies offering L2 metroE than L3 in the backhaul space. I have pushed for L3 but very few offer the speeds and reach required Cb
