Here are the 3 profiles applied on the transport nodes (ignore _VDS, it is not applied anywhere).

The first one is applied on the transport node n-vds uplinks (vmnic2 and vmnic3).

The second one on the TEP interface of the edge node (fp-eth0). The third on the uplink ports fp-eth1 and fp-eth2.

Edit:

I've also just checked, and the transfer rate between overlay networks attached to different edge node clusters is also affected. The other ledge cluster is identically configured as the one described above, just that the logical switch uses another subnet for adressing.

Also - AFAIK the transport node TEPs as well as the edge TEPs can use IPs from the same subnet. I could not find contradictory information. I know that when you use NSX-T lower than 3.1 in regards of VLANs in the transport network, but this occurs only when you use the VDS 7 exclusively to channel all traffic. This is not the case here.
