Why is OMP adjacency important in the SD-WAN control plane?

• A. OMP adjacency must be established between vEdge and vSmart to share routes
• B. OMP updates are optional
• C. OMP is used for DHCP
• D. OMP is deprecated

Answer: (A)

OMP adjacency between the edge device and the central controller is what makes the SD-WAN control plane functional. OMP, the Overlay Management Protocol, carries the per-VPN routing information, next-hop data, and policy configurations from the vSmart controller to the vEdges. When a vEdge establishes this OMP session with vSmart, it receives the routing tables and policy rules needed to reach remote sites and apply the defined behaviors across the WAN. Without this adjacency, the edge would not obtain updated routes or central policy, so the overlay cannot converge and traffic wouldn’t follow the intended paths. DHCP handling and deprecation aren’t related to OMP, and in current deployments OMP is not deprecated.
