The following tunnel service statuses are reported:
Not Ready (status color ORANGE ): Indicates that the service is in the process of being provisioned at the Infoblox POP (service location). This is a one-time state; it will not revert back to this state once it changes.
Ready (status color ORANGE): Indicates the backend for the tunnel(s) is provisioned, but the link is not physically connected at the customer site. This is a one-time state; it will not revert to this state once it changes.
Connected (status color GREEN): All tunnels are active and operational on both ends: both the Infoblox PoP and the customer site (router).
Not Connected (status color RED): Indicates that all tunnels are down.
