Ok. NSX-V 6.4.1
You must be using a DLR (this is also seen in the Edge section of NSX).
For bridging, the traffic is switch from VXLAN (Logical Switch) to VLAN by the DLR control VM. So where ever this DLR VM is placed is where the traffic is bridged. It is not possible to have 2 of these bridging VMs for the same VXLAN/VLAN conversion as you risk causing a layer 2 loop.
You can find the DLR control VM position in the host and clusters are of vSphere.
If you are doing this for 10/20/30 or more VLANs you could create 2 DLRs for bridging, have a DLR on each ESXi host and have half the bridges on one and the other half on the other. It's not perfectly balanced by might help your situation.
