County IT redistributes service-side BGP prefixes into OMP at a regional SD-WAN hub. What concern should engineers prioritize?
Select an answer to reveal the explanation.
Short Explanation
Redistribution is a two-way street with no traffic cop unless you add filters—BGP routes into OMP can bounce right back and create loops. Be picky about what enters the overlay at the county hub. Dumping the whole Internet table into OMP is a scalability nightmare, and STP has nothing to do with OMP best-path.
Full Explanation
At SD-WAN hubs, service-side routing protocols such as BGP often redistribute into OMP so branch overlays learn data-center or campus prefixes. Engineers must apply route filtering, tags, or policy to prevent mutual redistribution loops and to limit what enters the overlay. Injecting unfiltered Internet tables into OMP is operationally unsafe. Site-IDs remain required for overlay topology, and spanning-tree does not select OMP paths.
