300-415 Question 159
Single answerAn enterprise is implementing Cisco SD-WAN in its network and plans to integrate EIGRP as the routing protocol between its branch sites and the data center. The network administrator has configured EIGRP at the branch sites and the data center, and now plans to redistribute EIGRP routes into OMP (Overlay Management Protocol). What must the administrator ensure when performing route redistribution for EIGRP into OMP for proper route propagation?
- A
EIGRP routes must be tagged with a specific route tag for OMP to accept them.
- B
EIGRP must advertise its routes as internal routes only to be redistributed into OMP.
- C
The advertised EIGRP routes must be redistributed into OMP on the edge routers (vEdges).
- D
The edge routers (vEdges) must have EIGRP configured as the underlay routing protocol.
Show answer and explanation
Correct answer: C
Explanation
When integrating EIGRP with Cisco SD-WAN, the EIGRP routes from branch sites and data centers must be redistributed into OMP on the edge routers (vEdges). This redistribution enables the routes to be shared across the SD-WAN overlay network, ensuring proper route propagation between sites. Configuration of the underlay routing protocol or tagging of routes is not a requirement for the redistribution process.
- A. Incorrect.
EIGRP routes do not require a specific tag for redistribution into OMP. OMP uses route policies for control, but tagging is optional.
- B. Incorrect.
EIGRP routes can be internal or external for redistribution into OMP; this is not a strict requirement.
- C. Correct.
To propagate EIGRP routes into the SD-WAN overlay, they need to be redistributed into OMP on the edge routers (vEdges). This ensures the routes are advertised across the SD-WAN fabric.
- D. Incorrect.
EIGRP does not need to be the underlay routing protocol on the edge routers (vEdges) for redistribution into OMP. The underlay protocol and the overlay protocol operate independently.
