Use this procedure to configure a tier-0 VRF gateway for EVPN Route Server mode.

Procedure

  1. With admin privileges, log in to NSX Manager.
  2. Select Networking > Tier-0 Gateways.
  3. Add a VRF gateway.
    1. Click Add Gateway > VRF.
    2. Enter a name for the gateway.
    3. 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.
  4. 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.
    1. 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.
    2. 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.
    3. Click Add and then Apply.
  5. 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.
    1. For L2 VNI, click Set > Add L2 VNI.
    2. Select an L2 VNI.
      The VNI must be unique and belong to the VLAN-VNI mappings from an EVPN tenant.
    3. Enter the route distinguisher.
    4. For Route Targets, click Set > Add.
      • 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.
    5. Click Add and then Apply.
    6. 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.
  6. Click Save and then Yes to continue configuring the VRF gateway.
  7. Expand the Route Re-distribution section.
    1. Click Set > Add Route Re-Distribution.
    2. Enter a name for the re-distribution policy.
    3. Click Set to select available sources, such as tier-0 connected interfaces and segments.
    4. Click Apply.
    5. Click Add and then Apply.
