The correct answer for this question is C. The following sequence of commands could be used to check the BGP connection status between the Tier-0 Gateway and the upstream physical router on NSX Edge node:

  • enable <LR-D> - This command enters the Edge node's logical router context.

  • get vrf <ID> - This command shows the Virtual Routing and Forwarding (VRF) information associated with the logical router.

  • show bgp neighbor - This command displays the BGP neighbor information, including the status of the BGP connection between the NSX-T Tier-0 Gateway and the upstream physical router.

The other answer options are incorrect and here's why:

Option A:

  • set vrf <ID> - This command sets the VRF associated with the Edge node.

  • show logical-routers - This command displays the logical routers configured on the Edge node.

  • show <LR-D> bgp - This command is incorrect, as it tries to show BGP information for a specific logical router. However, it does not specify any VRF or neighbor information, so it won't display the BGP connection status between the Tier-0 Gateway and the upstream physical router.

Option B:

  • show logical-routers - This command displays the logical routers configured on the Edge node.

  • get vrf - This command is incorrect, as it does not specify any VRF information. Therefore, it won't display any BGP information.

  • show ip route bgp - This command displays the BGP routing table entries. However, it won't display any information about the BGP connection status between the Tier-0 Gateway and the upstream physical router.

Option D:

  • get logical-routers - This command displays the logical routers configured on the Edge node.

  • vrf <number> - This command specifies the VRF number. However, it does not provide any information about the BGP connection status.

  • get bgp neighbor - This command displays the BGP neighbor information. However, it does not provide any specific information about the BGP connection status between the Tier-0 Gateway and the upstream physical router.
