300-420 Question 176
Select 3A global enterprise is deploying Cisco SD-WAN and wants to ensure efficient traffic routing between branch offices while maintaining centralized control. To achieve this, the IT team needs to configure the SD-WAN customer edge routers properly. Which two actions should the team prioritize during the deployment?
- A
Configure the appropriate TLOCs (Transport Locator) for each customer edge router to establish connectivity between branches.
- B
Enable OSPF on the customer edge routers to manage routing across the SD-WAN fabric.
- C
Deploy templates in Cisco vManage to standardize the policies and configurations for customer edge routers.
- D
Activate MPLS forwarding on customer edge routers to ensure compatibility with the SD-WAN overlay.
- E
Ensure each customer edge router is authenticated to the SD-WAN controller using certificates or pre-shared keys.
Show answer and explanation
Correct answers: A, C, E
Explanation
To deploy SD-WAN effectively on customer edge routers, the IT team must focus on enabling transport link communication (TLOCs), standardizing configurations through vManage templates, and securely authenticating routers to the SD-WAN controllers. These steps ensure proper connectivity, centralized management, and security in the SD-WAN deployment.
- A. Correct.
Configuring TLOCs is essential as they define the transport links and enable communication between customer edge routers in the SD-WAN fabric.
- B. Incorrect.
While OSPF can be used in traditional routing environments, SD-WAN typically relies on its own control plane mechanisms rather than OSPF for managing routing decisions.
- C. Correct.
Standardizing configurations using templates in vManage ensures consistency across customer edge routers and simplifies management and troubleshooting.
- D. Incorrect.
Activating MPLS forwarding is unrelated to SD-WAN overlay functionality as SD-WAN operates independently of MPLS forwarding mechanisms.
- E. Correct.
Authentication of customer edge routers is a critical step to establish trust and ensure security within the SD-WAN fabric.
