An enterprise is migrating from a traditional MPLS WAN to Cisco SD-WAN. The network team has deployed vEdge routers at all branch offices and a vSmart controller in the data center. The engineer configures a centralized control policy to influence path selection based on cost and latency. After the policy is activated, the engineer notices that some branches are not receiving the updated policy and are still using the default best-path selection. The vSmart is reachable from all branches, and the vEdge routers show that they are connected to the vSmart. What is the most likely reason for this issue?
