To configure an NSX-T Data Center edge gateway to be the egress point for a data center group, increase the scope of the edge gateway. The gateway then becomes shared across all data centers that participate in the group.

When you scope an edge gateway to a data center group, all routed networks that are attached to the edge gateway become attached to the data center group and scoped to it.

All new routed networks that you attach to the edge gateway belong to the data center group.

A routed network attached to an edge gateway which is scoped to a VDC can participate in a data center group only if the scope of the edge is increased to this data center group.


Verify that you have associated an existing NSX-T Data Center edge gateway with one of the VDCs that participate in the data center group.


  1. In the top navigation bar, click Networking and then click the Data Center Groups tab.
    The list of data center groups appears.
  2. Click the target data center group.
  3. Click Edge Gateway and then click Add Edge.
  4. Select one of the available edge gateways and click Save.


The scope of the edge gateway is increased to the data center group. The change of scope does not affect any existing underlying services or networks.
