Carrier Supporting Carrier (CSC): Allows an MPLS VPN provider to interconnect isolated sites over another provider’s backbone while keeping private VPN address spaces, as per IETF RFC 4364. Selective VRF Download: Downloads VRF FIB entries only to line cards with VRF membership, increasing chassis FIB scale and avoiding unnecessary entries. 6PE and 6VPE: Introduces IPv6 from the edge over an IPv4/MPLS backbone without IPv6 addressing restrictions or impact on the existing IPv4 core. |

| L2VPN Services | Virtual Private LAN Services (VPLS): Connects multiple sites in a single bridged domain over a managed IP/MPLS network, presents an Ethernet interface, and decouples service bandwidth from the physical interface. Hierarchical VPLS (HVPLS): Adds hierarchy at the VPLS edge for scale, supporting QinQ access and Ethernet over MPLS (pseudowire) access. Virtual Private Wire Service (VPWS) with EoMPLS: Transports Ethernet frames across an MPLS core using pseudowires for individual EFPs or entire ports. Pseudowire redundancy: Allows backup pseudowires to protect primary pseudowires. G.8032: Sub-50 ms protection for Ethernet traffic in ring topologies, compliant with ITU-T G.8032 v2 on Cisco ASR 9000 Series.
