300-415 Question 28
Single answerA network engineer is configuring a Cisco SD-WAN environment and is tasked with ensuring proper route distribution between vSmart controllers and the edge routers. The engineer wants to verify how vRoute is utilized in this process. Which statement accurately describes the role of vRoute in the Cisco SD-WAN architecture?
- A
vRoute is used by the vSmart controller to maintain and advertise the centralized routing policies.
- B
vRoute is responsible for providing encrypted data plane connectivity between SD-WAN edge devices.
- C
vRoute facilitates the distribution of OSPF and BGP routes directly between edge devices without involving the vSmart controller.
- D
vRoute is a proprietary protocol used by vManage to collect telemetry data from all edge devices.
Show answer and explanation
Correct answer: A
Explanation
In Cisco SD-WAN, vRoute is a critical component that the vSmart controller uses to maintain and advertise routing information and policies to the edge routers. It plays a central role in the control plane, ensuring that edge devices receive the appropriate routing updates and policies. This centralized approach simplifies route management and policy enforcement in the SD-WAN environment.
- A. Correct.
Correct. vRoute is a foundational component of the Cisco SD-WAN solution used by the vSmart controller to maintain and distribute centralized routing policies to the edge routers.
- B. Incorrect.
Incorrect. vRoute is not involved in establishing encrypted connections. The data plane connectivity is handled by IPsec tunnels between edge devices.
- C. Incorrect.
Incorrect. vRoute does not facilitate direct route distribution between edge devices. It enables route exchange via the vSmart controller, which acts as a centralized policy engine.
- D. Incorrect.
Incorrect. vRoute is not a telemetry protocol. Telemetry data is primarily managed by vManage using different mechanisms.
