Hi Varga, I have some comments.
In section "3.2. Details of ICMP Error Handling for VPNs in SRv6 Networks", the solution requires "The solution uses a per-vrf SID (e.g., End.DT6) in the IP SA of the SRv6 encapsulated packets.". Would it be as good idea to use more specific SID (per-prefix or per-link)? If the user traffic uses SID as source, this will keep the traffic address aligned with the user traffic. See https://datatracker.ietf.org/doc/html/draft-yang-spring-sid-as-source-address-13#name-ip-vpn-over-srv6.

Thanks & Cheers Bala'zs -----Original Message----- From: Balázs Varga A Sent: Wednesday, February 25, 2026 9:18 AM To: IPv6 List <[email protected]> Subject: New draft: draft-varhal-6man-icmp-srv6-vpn-00.txt Hi, We have uploaded a new draft on "ICMP Error Handling for VPNs in SRv6 Networks". The draft proposes a solution that provides a native IPv6 method what does NOT have the drawbacks inherited by methods based on the MPLS based VPN ping or traceroute concept. It solves the problem that P nodes are not VPN aware without sending the ICMP error message to the egress PE router for a VPN lookup. It makes P nodes service agnostic and allows building IPv6-only core networks. Comments and suggestions are welcome.
