So what is a Transport Zone then?
A transport zone defines the span of a logical network and therefore the reach of transport nodes. It is not a security boundary.
In NSX-T we can have two types of transport zone one for Overlay (Geneve) networks and one for VLAN.
The overlay Transport Zone is used by the compute traffic to send the Geneve encapsulated frame while the VLAN transport zones are typically used for north / south connectivity for the Edges to the physical network, but they can also be used for production traffic which is the case when doing a basic Micro Segmentation deployment without the full NSX-T stack think VLAN portgroup on a vDS
Logical Switches or Segments as they are now also called can belong to only one Transport zone which would be an Overlay TZ.
So enough of the rambling lets get on and create these Transport Zone, this will not take long!
From the NSX console go to ‘System’ expand the ‘Fabric’ and select ‘Transport Zones’ then hit ‘Add’
Give the Transport Zone an name, an N-VDS Name and set the Traffic type to Overlay or VLAN.
For this one I’m creating the Overlay Transport Zone used by Geneve.
I’m going to add a VLAN Transport zone as well the first of which is VLANA this will be used by the first Edge node uplink interface to connect to the VLAN on the physical network for North South traffic.
I’m also adding a second uplink VLAN, VLANB this will be assigned to the second edge node uplink which will also connect to the physical network but on a different VLAN to first Uplink. This will allow me to peer with two BGP neighbours on the physical network and utilise ECMP.
And we are done nice and easy.
A nice quick post I like those. the next step is to create a custom uplink profile.
