2V0-41.24 Question 297
Select 3An organization is deploying NSX Edge Nodes to support north-south traffic for their workloads. During the deployment process, the administrator notices that the Edge Node is not forming a BGP neighbor relationship with the upstream router. Which of the following actions should the administrator take to troubleshoot and resolve the issue?
- A
Verify that the Edge Node's interface is correctly configured with an IP address and subnet mask.
- B
Ensure the Edge Node is in the same transport zone as the upstream router.
- C
Check that the BGP configuration on the Edge Node matches the configuration on the upstream router.
- D
Confirm that the MTU size on the Edge Node matches the MTU size of the physical network.
- E
Validate that the NSX-T license applied to the environment includes support for dynamic routing protocols such as BGP.
Show answer and explanation
Correct answers: A, C, D
Explanation
Establishing a BGP neighbor relationship requires proper IP connectivity, matching BGP configurations, and compatible MTU settings. While licensing and transport zones are important for other aspects of NSX-T deployment, they do not directly affect BGP neighbor formation. Troubleshooting should focus on connectivity, configuration, and MTU alignment to resolve the issue.
- A. Correct.
The IP address and subnet mask of the Edge Node's interface must be configured correctly to establish communication with the upstream router.
- B. Incorrect.
Transport zones are used for overlay and VLAN traffic within NSX-T. They are not relevant to BGP neighbor relationships, which depend on IP connectivity.
- C. Correct.
The BGP configuration, including AS numbers, neighbor IP, and authentication (if configured), must match between the Edge Node and the upstream router for the neighbor relationship to form.
- D. Correct.
MTU mismatches can cause packet drops, including BGP packets, preventing neighbor relationships from forming.
- E. Incorrect.
NSX-T licensing does not directly impact the BGP neighbor relationship. As long as NSX Edge Nodes are deployed, dynamic routing protocols like BGP are supported in eligible deployments.
