    abstract =  {This document defines BGP protocol extensions for encoding and carrying SRv6+ Per-Path Service Instruction information to support Virtual Private Network services. This is applicable when the VPN services are offered in a SRv6+ enabled IPv6 network such that the VPN payload is transported over IPv6. The Per-Path Service Instruction information is encoded in the IPv6 Destination Option Header in the IPv6 data packets.},
