Which OMP route type advertises transport locators in Cisco SD-WAN?

• A. Service route
• B. TLOC route
• C. VPN route
• D. Overlay route

Answer: (B)

In Cisco SD-WAN, the route type that carries the underlay connection details—the transport locators—is the TLOC route. TLOC routes advertise the transport locators, which are the IP addresses (underlay endpoints) of a site's edge, along with attributes like the transport color (types of links such as MPLS, Internet, or 4G) and encapsulation. This information lets other devices in the fabric know how to reach that site over the chosen transports and enables the SD-WAN to build and optimize the overlay path across multiple underlay links. VPN routes carry the actual customer networks inside a VPN, not the underlay endpoints. Overlay routes pertain to destinations learned across the fabric, not the underlay reachability. Service routes relate to services rather than transport endpoints.
