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
