By using route advertisement, you can create a fully routed network environment in an organization virtual data center (VDC).

You can decide which of the network subnets that are attached to the edge gateway backed by NSX to advertise to the dedicated tier-0 gateway.

If a subnet is not added to the advertisement filter, the route to it is not advertised to the tier-0 gateway and the subnet remains private.

Note: VMware Cloud Director advertises any organization VDC network that falls within the advertised route. Because of that, you do not need to create a filter for each subnet that is part of an advertised network.

Route advertisement is automatically configured on the NSX edge gateway.

VMware Cloud Director supports automatic route redistribution when you use route advertisement on an NSX edge gateway. Route redistribution is automatically configured on the tier-0 logical router which represents the dedicated tier-0 gateway.


  • Verify that the system administrator dedicated a tier-0 routerto an edge gateway backed by NSX in your organization.
  • Verify that you are an organization administrator or you are assigned a role that includes an equivalent set of rights.


  1. In the top navigation bar, click Networking and click the Edge Gateways tab.
  2. Click the edge gateway.
  3. Under Routing, click Route Advertisement and Edit.
  4. To add a subnet to be advertised, click Add.
  5. Add an IPv4 or IPv6 subnet.
    Use the format network_gateway_IP_address/ subnet_prefix_length, for example,
