Each VI workload domain requires at least one VLAN for the NSX-T host overlay network, and connect to a host overlay network. The VLAN drives the Transport Zone selection the VI workload domain can be a member of.
- Best practice is to configure a new VLAN for each VI workload domain to support the NSX-T host overlay network
- Applying the same VLAN to each VxRail cluster added to the VI workload domain ensures that all VxRail nodes will be members of the host overlay network.
- Follow these tasks for a new VLAN for the NSX-T host overlay network:
- Configure the VLAN on the adjacent leaf switches providing connectivity to the VxRail nodes
- Add the VLAN to each trunked port on the adjacent leaf switches providing connectivity to the VxRail nodes
- Ensure connectivity to a DHCP server supplying the IP addresses for the NSX-T edge uplinks
