Hi：
As a co-author of this two deafts.
· Do we need these different solutions?
----YES，draft-ietf-rtgwg-srv6-egress-protection-16 manually plan active/standby
and VPN protection relationships. Data packet needs to carry only one VPN SID.
It is applicable to scenarios where CE multi-homing is normalized and easy to
plan.
draft-cheng-rtgwg-srv6-multihome-egress-protection-05
automatically calculates active/standby VPN protection relationships based on
the primary and secondary VPN SIDs carried by the data plane. It is applicable
to the scenario where the CE multi-homing relationship is complex.
· Technical merits and drawbacks of each solution
---- draft-ietf-rtgwg-srv6-egress-protection-16 features low SRv6
encapsulation overhead, but requires manual planning of SRv6 protection
relationships.
Advantages of
draft-cheng-rtgwg-srv6-multihome-egress-protection-05: The SRv6 protection
relationship is automatically generated. No manual planning is
required.Disadvantages: An extra VPN SID needs to be encapsulated on the data
plane.，SRv6 Best Effort scenario SRH encapsulation is required.
I support the adoption of this draft as a co-author .
Thanks
Zhibo

(02/09/24 - 02/24/24)
Hi,
This email begins a 2 week WG adoption poll for the following draft:
draft-cheng-rtgwg-srv6-multihome-egress-protection-05 - SRv6 Egress Protection
in Multi-homed scenario
(ietf.org)<https://datatracker.ietf.org/doc/draft-cheng-rtgwg-srv6-multihome-egress-protection/>
Please review the document and indicate your support or objections by Feb 24th,
2024.
Please note that there is an existing WG
document:draft-ietf-rtgwg-srv6-egress-protection-16 - SRv6 Path Egress
Protection<https://datatracker.ietf.org/doc/draft-ietf-rtgwg-srv6-egress-protection/>
Which proposes fast protections for the egress node and link of an SRv6 path
through extending IGP and using Mirror SID. 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
