Before you enable ECMP routing, you must add a BGP neighbor and configure it with the newly added uplink information.

Prerequisites

Verify that the second edge node has an uplink port configured. See Add an Uplink Port for the Second Edge Node.

Procedure

  1. From your browser, log in to an NSX Manager at https://nsx-manager-ip-address.
  2. Select Routing from the navigation panel.
  3. Select the tier-0 logical router.
  4. Click the Routing tab and select BGP from the drop-down menu.
  5. Click Add under the Neighbors section to add a BGP neighbor.
  6. Enter the neighbor IP address.

    For example, 192.168.200.254.

  7. Select the local address from the drop-down menu.

    For example, uplink2 192.168.200.1.

  8. Enter the remote AS number.

    For example, 64511.

  9. Click Save.

    The newly added BGP neighbor appears.

  10. Click Edit next to the BGP Configuration section.
  11. Click the ECMP toggle button to enable ECMP.

    The Status button must be appear as Enabled.

  12. Click Save.

Results

Multiple ECMP routing paths connect the VMs attached to logical switches and the two Edge nodes in the Edge cluster.
