Hi 6man,

We have proposed an SRv6 local repair mechanism to provide endpoint protection. 
The document could be found in:
https://datatracker.ietf.org/doc/draft-chen-rtgwg-srv6-midpoint-protection/
The basic idea is quite straight forward: when the node finds that the 
neighbor, which the packet is supposed to be forwarded to, is an endpoint and 
it has failed, the node will do the proxy forwarding, including: SL--, replace 
the DA with the segment of the next endpoint, and forward the packet based on 
the DA.
Considering that the repair node which does the proxy forwarding could be a 
transit node, it is discussed in SPRING WG whether it violates RFC 8200; if it 
does, whether this behavior is allowed to provide local protection for endpoint.
We would like to hear the voice from 6man about this topic. Looking forward to 
your comments.

Best
Xuesong
