NVO3 WG,
Through offline discussion with David Black, the primary author of RFC 8014, we
concluded that "RFC 8014 was written based on 1-to-1 mapping model, at the same
time, RFC 8014 allows N-to-1 mapping."
Any other thoughts?
Best Regards,
Xiao Min

主 题 ：Question on the mapping between VAP and VNI
Dear NVO3 Architecture Authors,
Many thanks to the well defined NVO3 architecture.
I have a question on the mapping between VAP and VNI at one NVE, is it a 1-to-1
mapping or N-to-1 mapping?
In other words, is the following figure which is derived from Figure 2 of
RFC8014 reasonable?
