This document proposes a new approach for realizing classical L3VPN (vpnv4/vpnv6/6PE/6VPE) over Segment Routing (SR) networks. It significantly improves scalability and convergence of the L3VPN control plane. Furthermore, it naturally brings the benefits of All- Active multi-homing support to the classical L3VPN.
