Segments are used to connect VMs to Layer 2 networks, and they can be either VLAN or Overlay segments. For the Mgmt WLD, if AVN is enabled during the deployment, four segments are created. Two segments are created for the AVN networks, Region A and xRegion, to be used for the vRealize Suite of components. Two segments are created to allow Edge node traffic to flow through the ESXi hosts to the physical network. Following is the complete list of segments that are created with AVN enabled to support the virtual infrastructure for an SDDC.
Table 7. NSX-T Segments for Mgmt WLD
Segment |
Transport Zone |
VLAN (example) |
Region A Segment (AVN Network) |
Overlay |
None |
xRegion Segment (AVN Network) |
Overlay |
None |
Edge-uplink01 |
VLAN (edge uplink TZ) |
105 |
Edge-uplink02 |
VLAN (edge uplink TZ) |
106 |
For the VI WLD, no segments are created when a VI WLD is deployed and clusters are added. If the edge automation is used to deploy the NSX-T Edges from SDDC manger, the edge uplink segments are created at this time.
