Dear WG and the WG Chairs, I support the adoption, from the perspective of a network chip vendor.
The solution mentioned in [draft-cheng-rtgwg-srv6-multihome-egress-protection-05] includes pre-arranging backup service SIDs. When the tail node fails, it can easily realize the forwarding of the service SID of the next backup tail node. The chip logic is simple, easy to implement, and has low overhead, without affecting forwarding performance. We implement this draft in Centec network chip products.

As you discuss adopting draft-cheng-rtgwg-srv6-multihome-egress-protection, please also consider: Do we need these different solutions? Technical merits and drawbacks of each solution If there is any implementation of the proposals, please voice it. Authors, please respond to the list indicating whether you are aware of any IPR that applies to the draft.Also copying SPRING WG.Thanks, Yingzhen (RTGWG Co-chair)
