Which type of route advertisement of OMP can be verified?

VPN is not a type of route advertisement; OMP routes are associated with VPNs, and origin is a route attribute, not a type of advertisement.

Origin is a route attribute (e.g., connected, static, OMP), not a type of route advertisement comparable to OMP, TLOC, or service routes.

While OMP is the protocol and origin is an attribute, VPN is not a route advertisement type itself, making this choice less accurate than listing the specific route types.

OMP advertises OMP routes (network prefixes), TLOC routes (Transport Locators), and Service routes to facilitate communication and build the SD-WAN fabric. These three distinct types of route information propagated by OMP are essential for the overlay network's operation and can be verified in the control plane.
