2V0-41.24 Question 315
Select 3You are tasked with configuring a Tier-0 gateway in an NSX-T environment to establish dynamic routing with an upstream physical router using OSPF. During configuration, you ensure that the Tier-0 gateway is set to Active-Active mode. Which of the following steps must you perform to achieve a successful OSPF configuration?
- A
Configure an OSPF area and associate it with the Tier-0 gateway.
- B
Enable route redistribution for connected routes on the Tier-0 gateway.
- C
Assign an IP address to the Tier-0 gateway loopback interface for OSPF adjacency.
- D
Enable OSPF under the Tier-0 gateway's interface settings and assign an OSPF area.
- E
Configure the upstream physical router to use iBGP for dynamic routing instead of OSPF.
Show answer and explanation
Correct answers: A, B, D
Explanation
To configure OSPF on a Tier-0 gateway, you must define an OSPF area and enable OSPF on the relevant interfaces. Additionally, route redistribution must be configured for the Tier-0 gateway to propagate connected or other routes into OSPF. A loopback interface is not required for adjacency in OSPF, and iBGP is not relevant to this scenario as the requirement is specific to OSPF.
- A. Correct.
Correct: Configuring an OSPF area and associating it with the Tier-0 gateway is required for OSPF functionality. This defines the OSPF domain for exchanging routing information.
- B. Correct.
Correct: Enabling route redistribution for connected routes is necessary for the Tier-0 gateway to advertise its networks to upstream routers via OSPF.
- C. Incorrect.
Incorrect: Assigning an IP address to the Tier-0 gateway loopback interface is not required for OSPF adjacency. OSPF adjacency is established based on interface-specific configurations.
- D. Correct.
Correct: Enabling OSPF under the Tier-0 gateway's interface settings and assigning an OSPF area is essential for OSPF to form adjacencies and exchange routes.
- E. Incorrect.
Incorrect: Configuring the upstream physical router to use iBGP is unrelated to OSPF. iBGP is a different routing protocol and is not required in this scenario.
