Explanation

OMP in Cisco SD-WAN

OMP (Overlay Management Protocol) is the control-plane protocol in Cisco SD-WAN that runs between vSmart controllers and WAN Edge routers. It advertises network prefixes and their attributes (routes, next-hops, and TLOCs) across the overlay - making A correct - and it also distributes crypto keys used to establish IPsec tunnels between WAN Edge devices, making D correct.

Why the distractors are wrong:

• B is incorrect because policies are configured on vManage (the management plane) and then pushed to vSmart, not created by OMP itself.
• C is incorrect because gathering underlay infrastructure data is a function of BFD (Bidirectional Forwarding Detection) and the underlying transport, not OMP.
• E is incorrect because traffic segmentation and differentiation are achieved through VPNs/VRFs and data/control policies - OMP carries route information but doesn't perform segmentation itself.

Memory Tip: Think of OMP as a "postal service" for the SD-WAN overlay - it delivers two critical packages: routes (where to send traffic) and keys (how to secure it). If it's about building or configuring something, that's vManage's job.
