2V0-41.24 Question 356
Select 3You are tasked with deploying a Tier-1 Gateway and connecting it to a pre-configured VRF Gateway in an NSX-T environment. After the deployment, you notice that traffic is not being routed between the Tier-1 Gateway and the VRF Gateway. Which of the following steps must you ensure are correctly configured to resolve the issue?
- A
Ensure that the Tier-1 Gateway is linked to the VRF Gateway within the Tier-0 Gateway configuration.
- B
Verify that route advertisement is enabled on the Tier-1 Gateway for the required subnets.
- C
Configure a Service Interface on the VRF Gateway to establish communication with the Tier-1 Gateway.
- D
Ensure that the Tier-1 Gateway is set to Active-Active mode for high availability.
- E
Verify that the VRF Gateway has a route pointing to the Tier-1 Gateway's connected segment.
Show answer and explanation
Correct answers: A, B, E
Explanation
To connect a Tier-1 Gateway to a VRF Gateway, the Tier-1 Gateway must first be linked to the VRF Gateway through the Tier-0 Gateway. Additionally, proper route advertisement must be configured on the Tier-1 Gateway to ensure that prefix information is shared. Lastly, the VRF Gateway must have routing information that directs traffic to the Tier-1 Gateway. These steps ensure successful connectivity and traffic flow between the two gateways.
- A. Correct.
Correct: The Tier-1 Gateway must be linked to the VRF Gateway via the Tier-0 Gateway configuration. This establishes the hierarchical connection required for routing.
- B. Correct.
Correct: Route advertisement must be enabled on the Tier-1 Gateway to propagate subnet information to the VRF Gateway.
- C. Incorrect.
Incorrect: A Service Interface is not required for connectivity between a Tier-1 Gateway and a VRF Gateway. Service Interfaces are typically used for external connectivity.
- D. Incorrect.
Incorrect: Active-Active mode is a high availability configuration and is not directly relevant to resolving routing issues between the Tier-1 and VRF Gateways.
- E. Correct.
Correct: The VRF Gateway requires a route pointing to the Tier-1 Gateway's connected segment to correctly forward traffic.
