Hi SPRING WG, My co-authors and I have proposed a draft in BESS WG which defines No-Further-FRR-flag and Anycast-flag for SRv6 Service SIDs carried in BGP messages: https://datatracker.ietf.org/doc/draft-liu-bess-multihome-srv6-service-sid-flag/
The draft is to address the following issues in multihoming SRv6-based BGP service, including both L3VPN and EVPN: 1. Use no-further-FRR service SID for the protection of egress link, without worrying about loops; 2. Use anycast service SID for load balancing (since IGP Anycast-flag may be lost after summarization). IGP now has Backup-flag and Anycast-flag for SRv6 SID/Locator. Similarly, the draft extends BGP with No-Further-FRR-flag and Anycast-flag for SRv6 Service SID. We gave a presentation in BESS WG this Monday: https://datatracker.ietf.org/meeting/118/materials/slides-118-bess-draft-liu-bess-multihome-srv6-service-sid-flag-02 The chair of BESS WG recommended us to get more feedback from SPRING WG. Any comments would be appreciated.
