For routing to work on the uplink from the tier-0 router, connectivity with the top-of-rack device must be in place.



  1. Log in to the NSX Edge CLI.
  2. On the NSX Edge, run the get logical-routers command to find the VRF number of the tier-0 service router.
    nsx-edge-1> get logical-routers
    Logical Router
    UUID        : 736a80e3-23f6-5a2d-81d6-bbefb2786666
    vrf         : 0
    type        : TUNNEL
    Logical Router
    UUID        : 421a2d0d-f423-46f1-93a1-2f9e366176c8
    vrf         : 5
    type        : SERVICE_ROUTER_TIER0
    Logical Router
    UUID        : f3ce9d7d-7123-47d6-aba6-45cf1388ca7b
    vrf         : 6
    type        : DISTRIBUTED_ROUTER
    Logical Router
    UUID        : c8e64eff-02b2-4462-94ff-89f3788f1a61
    vrf         : 7
    type        : SERVICE_ROUTER_TIER1
    Logical Router
    UUID        : fb6c3f1f-599f-4421-af8a-99692dff3dd4
    vrf         : 8
    type        : DISTRIBUTED_ROUTER
  3. Run the vrf <number> command to enter the tier-0 service router context.
    nsx-edge-1> vrf 5
  4. On the tier-0 service router, run the get route command and make sure the expected route appears in the routing table.
    Notice that the route to the TOR appears as connected (c).
    nsx-edge1(tier0_sr)> get route
    Flags: t0c - Tier0-Connected, t0s - Tier0-Static, b - BGP,
    t0n - Tier0-NAT, t1s - Tier1-Static, t1c - Tier1-Connected,
    t1n: Tier1-NAT, t1l: Tier1-LB VIP, t1ls: Tier1-LB SNAT,

    t0c> * fe80::/64 is directly connected, downlink-282, 08w4d03h
  5. Ping the TOR.
    nsx-edge1(tier0_sr)> ping
    PING ( 56 data bytes
    64 bytes from icmp_seq=0 ttl=64 time=2.822 ms
    64 bytes from icmp_seq=1 ttl=64 time=1.393 ms
    --- ping statistics ---
    3 packets transmitted, 2 packets received, 33.3% packet loss
    round-trip min/avg/max/stddev = 1.393/2.107/2.822/0.715 ms


Packets are sent between the tier-0 logical router and physical router to verify a connection.

What to do next

Depending on your networking requirements, you can configure a static route or BGP. See Configure a Static Route in Manager Mode or Configure BGP on a Tier-0 Logical Router in Manager Mode.
