VCP-VCF Administrator 2024 Question 52
Select 3An organization is deploying VMware Cloud Foundation with NSX-T Data Center. They have configured an NSX Edge Cluster to connect with their physical data center using Border Gateway Protocol (BGP). During testing, they notice that some routes from the physical network are not being advertised to the NSX-T environment. Which of the following actions should the administrator take to resolve this issue?
- A
Verify that BGP neighbor relationships are correctly established between the NSX Edge Cluster and the physical router.
- B
Ensure the BGP route filtering policies on the NSX Edge Cluster allow the required routes to propagate.
- C
Check if the NSX Edge Cluster is configured to use OSPF instead of BGP.
- D
Confirm that the NSX Edge Cluster has the necessary Tier-0 logical router configured for BGP route advertisement.
- E
Enable automatic summarization of routes on the physical router to simplify BGP route propagation.
Show answer and explanation
Correct answers: A, B, D
Explanation
To resolve the route propagation issue in this scenario, the administrator must ensure that the BGP configuration on the NSX Edge Cluster aligns with the requirements for successful route exchange. This includes verifying BGP neighbor relationships, configuring appropriate route filtering policies, and ensuring the presence of a Tier-0 logical router for route advertisement. OSPF is not relevant, and enabling automatic summarization is not required for this scenario.
- A. Correct.
BGP neighbor relationships must be correctly established between the NSX Edge Cluster and the physical router to enable route exchange. If this is not configured properly, routes will not propagate.
- B. Correct.
Route filtering policies on the NSX Edge Cluster can control which routes are advertised or received. Incorrect filtering policies can block the required routes from propagating.
- C. Incorrect.
OSPF is not relevant in this scenario, as the question specifically involves BGP. Configuring OSPF instead of BGP would not resolve the issue.
- D. Correct.
A Tier-0 logical router on the NSX Edge Cluster is required to facilitate BGP route propagation. Without it, BGP advertisements cannot occur.
- E. Incorrect.
Enabling automatic summarization is not necessary for BGP and can sometimes lead to incorrect route propagation due to oversimplification. BGP typically relies on explicit configuration for route propagation.
