A network administrator is building a centralized data policy in Cisco Catalyst SD-WAN Manager to redirect specific application traffic from branch VPN 10 toward a data center service. During validation, the administrator notices the policy is not taking effect on traffic sourced from the branch LAN. The policy sequence, match conditions, and action are all confirmed correct. Which configuration element is most likely missing or misapplied that would cause the branch-originated traffic to be ignored by the centralized data policy?
