Which type of route advertisement of OMP can be verified?

Options

AOrigin, TLOC, and VPN
BOrigin, TLOC, and service
COMP, VPN, and origin
DOMP, TLOC, and service

Explanation

OMP, the Overlay Management Protocol, advertises various types of routes to build and maintain the SD-WAN fabric, which can be verified.

Common mistakes.

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

Concept tested. OMP route advertisement types
