The engineer is configuring the vSmart controller to transmit the initial set of non-best routes to the vEdge routers. Which configuration command is required under the Overlay Management Protocol…

The 'send-backup-paths' command, configured under the OMP section of the vSmart controller, enables advertisement of all non-best routes to vEdge routers so they can maintain backup path awareness and achieve faster convergence upon primary path failure.

'send-path-limit' controls the maximum number of equal-cost paths sent to a vEdge, not the transmission of non-best backup routes.

'controller-send-path-limit' is not a valid Cisco SD-WAN OMP command and would be rejected by the CLI parser.

'send backup paths' uses incorrect syntax with spaces instead of hyphens and is not a recognized OMP configuration command.
