Dear Spring Authors

Please respond to this question the WG has related to which of the three
SRv6 forwarding mechanisms called  flavors was inclusive of the compression
analysis draft.

The Analysis draft is ambiguous as to which SRv6 forwarding plane flavor
was part of the analysis.

This is a critical question that has come up by the WG and Chairs, and
answering this question will help pave the way to an adoption call for
C-SID.

Kind Regards

Gyan
