Physical to Virtual Server Communication in NSX

When I was attending the NSX course, the instructor told me NSX must use VXLAN to communicate, also for my understanding, if the environment has physical server, bridging is required for communication between VXLAN and VLAN.

Need to find out of if NSX can use VLAN to cummunicate directly to VLAN without going through bridging or not? Or what's the best way for virtual server to physical server communication which are sitting in the same VLAN/Subnet?

Thanks for assistance.

Hi,

It depends.

if the virtual server connected to the vxlan and the server connected to the vlan are in the same subnet and you want to communicate, yes, you need a bridge. (layer2)

If the servers are in 2 different subnets, you do not need a bridge. You can route. (layer3)

A Distributed logical router or an edge can connect to vxlan and can connect to a vlan (distributed portgroup on a dvswitch).

‌VLAN to VLAN is not something you would use NSX bridging for. What function do you actually want NSX to perform in your scenario? A VLAN-backed dvPortgroup would provide the basic connectivity in general vSphere networking terms...
