QuestionQ49

Unknown / not found in official Broadcom sources

An administrator is diagnosing North-South routing in an NSX environment in which a Tier-0 Gateway peers with an upstream physical router through Border Gateway Protocol (BGP).

Although route redistribution is configured, the administrator finds that external routes are absent from the Tier-0 Gateway routing table. To determine whether a failed BGP session is the cause, the administrator chooses to check BGP neighbor status directly from the NSX Edge Node CLI.

Which command sequence should be used to check BGP status on an NSX Edge node?

  • A
    • enable <LR-D>- get vrf <ID>- show bgp neighbor
  • B
    • set vrf <ID>- show logical-routers- show <LR-D> bgp
  • C
    • get gateways- vrf <number>- get bgp neighbor
  • D
    • show logical-routers- get vrf- show ip route bgp
Explanation

On an NSX Edge node, get gateways identifies the gateway and its VRF, vrf <number> enters the relevant Tier-0 Service Router context, and get bgp neighbor displays BGP peer information, including the session state. Broadcom’s NSX CLI reference documents get bgp neighbor in the Tier-0 Service Router context and shows that its output includes BGP state.
