Which routes are similar to the IP route advertisements when the routing information of WAN Edge routers is learned from the local site and local routing protocols?

BGP is a local routing protocol that can run on a WAN Edge, but it's not the protocol that advertises this information into the SD-WAN overlay itself; OMP does that.

OMP (Overlay Management Protocol) routes are used by WAN Edge routers to advertise their locally learned routing information, including routes learned from local routing protocols like BGP or OSPF, to the vSmart controllers. These routes are then distributed by vSmart controllers to other WAN Edge routers in the SD-WAN fabric.

TLOC (Transport Location) refers to the interface on a WAN Edge router that connects to the transport network, identifying the tunnel endpoint, not the advertised IP routes.

A service route is a specific type of OMP route used to redirect traffic for a particular service, rather than a general category for all IP route advertisements.
