A WAN Edge device has several service VPNs with no routing protocol configured in the service VPN. The device must be configured so that all connected routes visible in OMP for VPN 10. Which…
The correct answer is D. vpn 10 name "**** Service VPN 10 *****" omp advertise connected. To make connected routes within a specific service VPN (VPN 10) visible in OMP, the advertise connected command must be configured under that VPN's OMP settings.

Why each option
To make connected routes within a specific service VPN (VPN 10) visible in OMP, the `advertise connected` command must be configured under that VPN's OMP settings.
The `redistribute connected` command is typically used within other routing protocols or in a global OMP context, whereas `advertise connected` is the precise command for injecting a service VPN's directly connected routes into OMP.
The `advertise connected` command is not correctly applied in the global `omp` context to target connected routes of a specific service VPN; it needs to be under the `vpn <vpn-id> omp` hierarchy.
The `redistribute connected` command in the global `omp` context would generally redistribute all connected routes into OMP, which is not specifically targeted to only VPN 10 as required.
The `advertise connected` command, applied within the `omp` context of a specific `vpn` (e.g., `vpn 10`), explicitly instructs the WAN Edge device to announce its directly connected interface routes within that VPN to the Overlay Management Protocol (OMP). This action ensures that those routes are propagated through the SD-WAN control plane.
