A museums and culture department asks what OMP contributes in Cisco SD-WAN. Which statement best describes OMP’s role?
Select an answer to reveal the explanation.
Short Explanation
OMP is the overlay’s gossip protocol—Edges and vSmarts share which site prefixes and TLOCs exist, like museums swapping exhibit maps. It is not BFD, not a substitute for IPsec encryption, and not a LAN spanning-tree replacement. Without OMP, the overlay does not know how to find the other buildings.
Full Explanation
Overlay Management Protocol (OMP) runs between WAN Edges and vSmart controllers to advertise overlay prefixes, TLOC information, service routes, and attributes used for path selection. Underlay liveliness often uses BFD on transports, which is separate from OMP. Data-plane security still relies on IPsec (or equivalent) for tunnel encapsulation; OMP does not eliminate encryption. OMP is unrelated to Layer-2 STP inside wiring closets.
