Correct answer: OMP.
Why this is the answer
The OMP (Overlay Management Protocol) table on the vSmart controller stores service routes (also known as OMP routes or vRoutes) learned from WAN Edge routers. OMP is the control plane protocol in Cisco SD-WAN that advertises reachability information, including service routes, between vSmart controllers and WAN Edge routers. This table is crucial for building the network topology and enabling routing decisions within the SD-WAN fabric. The RIB (Routing Information Base) is a general routing table found on routers, but in SD-WAN, OMP specifically handles the overlay routing information. The FIB (Forwarding Information Base) is derived from the RIB and is used for actual packet forwarding; it doesn't store the learned routes themselves. TLOC (Transport Locator) refers to the physical interface and transport information, not the service routes.
