Use this procedure to configure a tier-0 VRF gateway for EVPN Route Server mode.
Procedure
- With admin privileges, log in to NSX Manager.
- Select Networking > Tier-0 Gateways.
- Add a VRF gateway.
- Click Add Gateway > VRF.
- Enter a name for the gateway.
- Select a tier-0 gateway with EVPN Route Server mode enabled to connect to.
Some advanced configurations are inherited from the parent tier-0 gateway, such as HA mode, edge cluster, internal transit subnet, T0-T1 transit subnets, and BGP Local ASN.
- Expand the VRF Settings section and configure the L3 VRF settings.
Note: The L3 VRF settings correspond with the EVPN RT-5 routes advertised and received from the data center gateways. The imported/exported RTs needs to match with the corresponding L3 VRF configuration in the data center gateway side.
- Enter the route distinguisher.
If the connected tier-0 gateway has RD Admin Address configured, the Route Distinguisher field is automatically populated. Enter a new value if you want to override the assigned route distinguisher.
- For Route Targets, click Set > Add Route Target to add route targets.
- For EVPN, only the Manual mode is supported.
- Specify one or more Import Route Targets to install the desired routes from BGP peers to the VRF routing table.
- Specify one or more Export Route Targets to label advertised VRF routes.
- Click Add and then Apply.
- Enter the route distinguisher.
- Configure the L2 VNI settings.
Note: The L2 VNI settings correspond with the EVPN RT-3, RT-2, and RT-1 routes advertised and received from the data center gateways. The imported/exported RTs needs to match with the corresponding L2 VNI configuration in the data center gateway side.
- For L2 VNI, click Set > Add L2 VNI.

The VNI must be unique and belong to the VLAN-VNI mappings from an EVPN tenant.
- Enter the route distinguisher.

- For EVPN, only the Manual mode is supported.
- Specify one or more Import Route Targets to install the desired routes from BGP peers to the VRF routing table.
- Specify one or more Export Route Targets to label advertised VRF routes.
- Click Add and then Apply.
- For VTEP Groups, click the toggle to enable or disable the creation of VTEP groups with data center gateways for the L2 VNI.
Note: The VTEP Groups option will enable northbound L2ECMP EVPN multihoming between the VNF and DC gateways.
- Click Save and then Yes to continue configuring the VRF gateway.
