Which type of route prefixes represents prefixes received from a local site via an SD-WAN Edge router in a Cisco SD-WAN architecture?

TLOC routes (Transport Locator routes) represent the WAN Edge router's public-side interface IP address, transport color, and encapsulation, not the prefixes behind the local site.

vRoutes, also known as service routes, represent prefixes that are learned from the local site's network via the SD-WAN Edge router and then advertised into the SD-WAN overlay by the vSmart controller. These are the application-level routes used for overlay traffic forwarding.

Multicast routes are specifically for multicast traffic and are a subset, not the general term for all local site prefixes.

Service routes is a broader term that sometimes encompasses vRoutes, but vRoutes is the more precise and commonly used term in Cisco SD-WAN for routes learned from local services and advertised into the overlay.
