300-415 Question 97
Single answerAn engineer is troubleshooting control plane connectivity issues in a Cisco SD-WAN network. The vEdge router is not forming a connection with the vSmart controller. The engineer verifies that the vEdge has the correct system IP and organization name configured. However, the control connection is still not established. What should the engineer check next to resolve the issue?
- A
Verify that the vEdge router has a valid certificate installed.
- B
Check if there is a mismatch in the TLOC color configuration between the vEdge and vSmart.
- C
Ensure that the vSmart controller is reachable over the configured transport network.
- D
Verify that the OMP (Overlay Management Protocol) is enabled on the vEdge router.
Show answer and explanation
Correct answer: A
Explanation
Control plane connectivity between vEdge and vSmart requires valid certificates for mutual authentication. In this scenario, since the system IP and organization name are correctly configured, the next step is to ensure that the vEdge has a valid certificate installed. This is a common cause of control connection issues in Cisco SD-WAN deployments.
- A. Correct.
A valid certificate is required for control plane connectivity between vEdge and vSmart. Without a valid certificate, the vEdge cannot authenticate itself to the vSmart, preventing the control connection from being established.
- B. Incorrect.
TLOC color mismatches are related to data plane connectivity issues and do not directly affect control plane connections between vEdge and vSmart.
- C. Incorrect.
While network reachability is necessary, the issue described in the scenario does not indicate a transport network problem since the system IP and organization name have already been verified.
- D. Incorrect.
OMP is used for route advertisement and is not directly involved in establishing control plane connectivity between vEdge and vSmart.
