Explanation

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.

Common mistakes.

A. 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.
B. 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.
C. 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.
