Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 118

Which routing protocol is used to exchange control plane information between vSmart controllers and WAN Edge routers in the Cisco SD-WAN secure extensible network?

Answer options

• A. BGP
• B. OSPF
• C. BFD
• D. OMP

Correct answer: D

Explanation

OMP (Overlay Management Protocol) is specifically designed for the Cisco SD-WAN architecture, enabling the exchange of control plane information. BGP and OSPF are traditional routing protocols used for data plane routing but do not serve this specific purpose in SD-WAN. BFD is a protocol used for detecting faults in the forwarding path but is not involved in control plane communication.
