Creating a Universal Transport Zone in NSX 6.2

One of the new features in NSX 6.2 is the ability to span logical networks across multiple vCenters. In order to do this we now have the ability to create a Universal Transport Zone than can contain clusters from different vCenters. In my lab I'm going to create three new Transport Zones:

PA-TransportZone - A dedicated transport zone for the Palo Alto DataCenter that will contain the PA-Compute and PA-MGMT clusters.

NY-TransportZone - A dedicated transport zone from the New York DataCenter that will contain the NY-Compute and NY-MGMT clusters.

Universal-TransportZone - A dedicated transport zone that will contain all four clusters that span over two vCenters.

In order to achieve this we first need to create local and universal segment ID pools.  Segment ID pools are used to allocate VNI's (VXLAN Network Identifiers) to logical networks. I'm going to use the following VNI pools:

Palo Alto Segment ID Pool - 5000-5999
New York Segment ID Pool - 6000-6999
Universal Segment ID Pool - 10000-10999

This will allow me to create 1000 logical networks in Palo Alto and New York but then also another 1000 than can span both vCenters.

To start log into the vSphere Web Client and navigate to Installation -> Logical Network Preparation and then click on the Segment ID tab.  Ensure that you are connected to the NSX Manager that has the Primary Role:


Edit the setting and add the segment ID pools for the primary NSX Manager:


Click OK and then change to the secondary NSX Manager.  You should already notice that the Universal Segment ID's have already been populated.  Add the segment ID's for the secondary ensuring that they don't overlap with the Universal segment ID's:



Click on the Transport Zone tab and create a new Transport Zone.  The first Transport Zone we are going to create is the PA-TransportZone and add the two Palo Alto DataCenter clusters:


Now create a new Transport Zone but ensure you tick the option to Mark this object for Universal Synchronization and add the two Palo Alto DataCenter Clusters again:


We now have two Transport Zones:


Switch to the secondary NSX Manager and you will notice that we already have the Universal Transport Zone available.  Add the two New York DataCenter clusters to it:



Finally create the second local transport zone and add the two New York DataCenter clusters to it:


We should end up with a Local and Universal Transport Zone in both the Palo Alto and New York sites:
