Understanding Cross-vCenter NSX Multi-Site and Single Site Architecture

cross-vCenter NSX environment allows you to use the same logical switches and other network objects across multiple vCenter NSX setups. The vCenters can be located in the same site, or in different sites.

Whether the cross-vCenter NSX environment is contained within a single site or crosses multiple sites, a similar configuration can be used. These two example topologies consist of the following:

  • A universal transport zone that includes all clusters in the site or sites.

  • Universal logical switches attached to the universal transport zone. Two universal logical switches are used to connect VMs and one is used as a transit network for the router uplink.

  • VMs added to the universal logical switches

  • A universal logical router with an NSX Edge appliance to enable dynamic routing. The universal logical router appliance has internal interfaces on the VM universal logical switches and an uplink interface on the transit network universal logical switch.

  • Edge Services Gateways (ESGs) connected to the transit network and the physical egress router network.
