Use CLI to verify that the ECMP routing connection to neighbor is established.

Prerequisites

Verify that ECMP routing is configured. See Add an Uplink Port for the Second Edge Node for ECMP in Manager Mode and Add a Second BGP Neighbor and Enable ECMP Routing in Manager Mode.

Procedure

  1. Log in to the NSX Manager CLI.
  2. Get the distributed router UUID information.
    get logical-routers 
    Logical Router
UUID        : 736a80e3-23f6-5a2d-81d6-bbefb2786666
vrf         : 2
type        : TUNNEL

Logical Router
UUID        : d40bbfa4-3e3d-4178-8615-6f42ea335037
vrf         : 4
type        : SERVICE_ROUTER_TIER0

Logical Router
UUID        : d0289ba4-250e-41b4-8ffc-7cab4a46c3e4
vrf         : 5
type        : DISTRIBUTED_ROUTER

Logical Router
UUID        : a6ee6316-2212-4171-99cc-930c98bcad7f
vrf         : 6
type        : DISTRIBUTED_ROUTER
  3. Locate the UUID information from the output. 
    Logical Router
UUID        : d0289ba4-250e-41b4-8ffc-7cab4a46c3e4
vrf         : 5
type        : DISTRIBUTED_ROUTER
  4. Type the VRF for the tier-0 distributed router.
    vrf 5
  5. Verify that the tier-0 distributed router is connected to the Edge nodes.
    get forwarding
    For example, edge-node-1 and edge-node-2.
  6. Enter exit to leave the vrf context.
  7. Verify that the tier-0 distributed router is connected.
    get logical-router <UUID> route
    The route type for the UUID should appear as NSX_CONNECTED.
  8. Start a SSH session on the two Edge nodes.
  9. Start a session to capture packets.
    set capture session 0 interface fp-eth1 dir tx

    set capture session 0 expression src net <IP_Address>

  10. Use any tool that can generate traffic from a source VM connected to the tier-0 router to a destination VM.
  11. Observe the traffic on the two Edge nodes.
