BGP based Virtual Private Network (VPN) Services over SRm6 enabled IPv6 networks

This document defines BGP protocol extensions for encoding and carrying SRm6 Tunnel Payload Forwarding information (TPF) to support Virtual Private Network services. This is applicable when the VPN services are offered in a SRm6 enabled IPv6 network such that the VPN payload is transported over IPv6. The Tunnel Payload Information is encoded in the IPv6 Destination Option Header in the IPv6 data packets.
