2V0-41.24 Question 332
Select 3An organization is deploying NSX-T and has configured a Tier-0 gateway to provide external connectivity. The network administrator wants to establish dynamic routing between the Tier-0 gateway and an external router using BGP. Which steps are required to properly configure BGP on the Tier-0 gateway?
- A
Enable BGP on the Tier-0 gateway and configure a BGP local AS number.
- B
Configure BGP neighbors under the Tier-0 gateway and specify their IP addresses.
- C
Assign a static route on the Tier-0 gateway pointing to the external router's network.
- D
Enable route redistribution for connected and static routes on the Tier-0 gateway.
- E
Configure the external router to use the same BGP AS number as the Tier-0 gateway.
Show answer and explanation
Correct answers: A, B, D
Explanation
To configure BGP on a Tier-0 gateway in NSX-T, you must enable BGP, configure a local AS number, and define BGP neighbors with their respective IP addresses. Additionally, to advertise routes through BGP, route redistribution must be enabled for connected and static routes. Static routes pointing to the external router are not required for BGP, as the protocol dynamically exchanges routes. The external router should use a different AS number than the Tier-0 gateway unless specific configurations like AS override are used.
- A. Correct.
Correct. Enabling BGP and configuring a local AS number is necessary for establishing a BGP session on the Tier-0 gateway.
- B. Correct.
Correct. BGP neighbors must be defined with their IP addresses to establish a BGP peering session.
- C. Incorrect.
Incorrect. Static routes are not required when using BGP, as dynamic routing will automatically handle route advertisement and learning.
- D. Correct.
Correct. Route redistribution ensures that connected and static routes are advertised via BGP to the external router.
- E. Incorrect.
Incorrect. The external router and Tier-0 gateway must use different BGP AS numbers to establish a BGP session unless using AS override or confederation.
