[linchangwang <[e-mail]>]

Hi：

       I support the adoption of this draft as a co-author .
I am not aware of any  IPR relevant to this draft.

The replies to several questions are as follows:

••  Do we need these different solutions?

----Yes, [draft-cheng-rtgwg-srv6-multihome-egress-protection-05] is suitable for scenarios where the ingress node can arrange primary and backup SIDs based on the idea of source routing.

••  Technical merits and drawbacks of each solution

【draft-ietf-rtgwg-srv6-egress-protection-16】: Requires control plane extension and Mirror sid extension, does not require ingress node awareness.

 【draft-cheng-rtgwg-srv6-multihome-egress-protection-05】: Does not require control plane extension, requires  ingress node to include the backup service SID in the encoding.

3.I If there is any implementation of the proposals, please voice it.

   ----H3C has implemented the egress protection method as mentioned in the draft document "draft-cheng-rtgwg-srv6-multihome-egress-protection-05".

Organization: New H3C Technologies.

Maturity Level: Beta

Version: draft-cheng-rtgwg-srv6-multihome-egress-protection-05



Thanks,

Changwang
