Use the CLI to verify from the tier-0 service router that a BGP connection to a neighbor is established.

Prerequisites

Verify that BGP is configured. See Configure BGP on a Tier-0 Logical Router.

Procedure

  1. Log in to the NSX Manager 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
    nsx-edge1(tier0_sr)> 
    
  4. Verify that the BGP state is Established, up.
