When a WAN Edge router is in the staging state, it creates control connections with the vSmart controller but does not create data tunnels. The staging state is used when a new WAN Edge router is being provisioned, and the router is not yet ready to forward data traffic. During the staging process, the router communicates with the vSmart controller to receive its configuration and policies, and to establish control connections that will be used to manage the router once it is activated.
Once the WAN Edge router has completed the staging process, it enters the valid state, at which point it is ready to create data tunnels and forward traffic. The backup state is used to designate a router that is configured to take over for an active router in the event of a failure, and the active state is used to designate a router that is actively forwarding traffic.
In summary, the WAN Edge router creates control connections but does not create data tunnels while in the staging state. The staging state is used during the provisioning process, while the valid state is used when the router is ready to forward data traffic. The backup and active states are used to designate routers that are configured for redundancy and are actively forwarding traffic, respectively.
