Hi,
I would like to repeat the question I have asked at the mike during the SPRING
WG session today about
draft-dong-spring-srv6-inter-layer-programming<https://datatracker.ietf.org/doc/html/draft-dong-spring-srv6-inter-layer-programming-04>:
How would the node that has allocated an End.XU SID for a specific underlay
link (i.e., non-IP) identify the Layer 2 encapsulation that has to be pushed on
the packet with the End.XU SID exposed?
The reference to End.X behavior in Section 4.2 of RFC
8986<https://datatracker.ietf.org/doc/html/rfc8986#section-4.2> looks incorrect
to me since End.X explicitly speaks about a L3 X-connect and usual Layer 2
helpers ARP and/or ND) would be applicable.
But this is not the case for a path for a non-IP path IMHO.
I may have missed the details of the response by the presenter, but my gut
feeling is that my question has not been answered.
Regards, and thanks n advance for the feedback,
Sasha
