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 in Manager Mode.

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

  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.
