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?

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? | Underlay Network (IP) | | | +---------------------------------------+ | | | Tunnel Overlay | +------------+---------+ +---------+------------+ | +----------+-------+ | | +-------+----------+ | | | Overlay Module | | | | Overlay Module | | | +---------+--------+ | | +---------+--------+ | | | | | | | NVE1 | | | | | | NVE2 | +--------+-------+ | | +--------+-------+ | | |VNI1 VNI1 | | | | VNI1 VNI1 | | | +-+-----------+--+ | | +-+-----------+--+ | |VAP1| |VAP2 | |VAP3| |VAP4 | +----+-----------+-----+ +----+-----------+-----+ | | | | -------+-----------+------------------+-----------+-------- | | Tenant | | ( ' ) ( ' ) ( ' ) ( ' ) (Ethernet) (IP Routing) (Ethernet) (IP Routing) ( _ ) ( _ ) ( _ ) ( _ ) | | | | TSI1| |TSI2 TSI3| |TSI4 +---+ +---+ +---+ +---+ |TS1| |TS2| |TS3| |TS4| +---+ +---+ +---+ +---+
