Just wondering, but what IP-capable MPLS switches are people using to deploy AE to residential internet connections? Most 48 port AE switches from repetuable vendors are crazy expensive, and I can't see how the ROI would ever work compared to GPON.
Why do you need MPLS? Most people just use regular L2 switches with some SAVI functionality (DHCP inspection, RA guard tec). When I did this, we happened to have an L3 switch there so I made each customer IPv6 (protocol based vlan) broadcast domain unique for each customer, and the L3 switch had built in DHCPv6-PD server. So just route a /51 to it, and it was a self contained IPv6 upstream router. For IPv4 we had a shared vlan and I didn't change that design at all.
For the FTTH deployment I am currently connected to, other end of my fiber is a big L2 chassi switch (~600 ports) with 10GE uplink to somewhere, and it does SAVI and then there is some BNG somewhere at the other end of this 10GE uplink.
