300-415 Question 157
Single answerA company has deployed a Cisco SD-WAN solution and is using EIGRP within its traditional branch sites. The company wants to integrate these sites into the SD-WAN fabric while ensuring that EIGRP routes are advertised to the SD-WAN overlay. Which configuration step is required on the SD-WAN edge device to achieve this integration?
- A
Enable EIGRP on the SD-WAN edge device using OMP (Overlay Management Protocol).
- B
Redistribute EIGRP routes into OMP on the SD-WAN edge device.
- C
Configure OMP as the routing protocol on branch devices instead of EIGRP.
- D
Establish a direct EIGRP adjacency between SD-WAN edge devices and remote branches.
Show answer and explanation
Correct answer: B
Explanation
To integrate EIGRP into a Cisco SD-WAN solution, the EIGRP routes must be redistributed into OMP on the SD-WAN edge device. This allows the EIGRP routes to be advertised across the SD-WAN overlay, enabling communication between branch sites. OMP acts as the overlay protocol, facilitating the exchange of routing information across the SD-WAN fabric.
- A. Incorrect.
Incorrect. Enabling EIGRP using OMP directly is not a valid configuration. OMP acts as the overlay protocol but does not replace EIGRP configuration.
- B. Correct.
Correct. Redistributing EIGRP routes into OMP ensures that EIGRP routes are advertised across the SD-WAN overlay and can be propagated to other sites.
- C. Incorrect.
Incorrect. Replacing EIGRP with OMP is not necessary. OMP is used for the overlay communication and works alongside existing routing protocols like EIGRP.
- D. Incorrect.
Incorrect. Establishing a direct EIGRP adjacency between SD-WAN edge devices and branches is not required. EIGRP routes are integrated into the overlay using redistribution into OMP.
