Hi Paul, Still catching up on emails post-holiday. If you have Ethernet to the CPE device then the tradition method of PPP + L2TP + RADIUS etc. adds in lots of overhead, complexity and state. In my opinion a clearer/simpler design would be to have the access nodes insert the circuit ID into DHCP requests coming from the CPE device and use PWHE to tunnel them back to a central box using standard MPLS and use the circuit ID to match static IP mappings. PPP and L2TP only exists in our network for ADSL based services and it’s just another couple technologies (plus RADIUS) that engineers need to know in addition to typical BGP/MPLS. Cheers, James.
