/**
 * <p>
 * State of the virtual interface.
 * </p>
 * <ul>
 * <li>
 * <p>
 * <b>Confirming</b>: The creation of the virtual interface is pending confirmation from the virtual interface owner. If
 * the owner of the virtual interface is different from the owner of the connection on which it is provisioned, then the
 * virtual interface will remain in this state until it is confirmed by the virtual interface owner.
 * </p>
 * </li>
 * <li>
 * <p>
 * <b>Verifying</b>: This state only applies to public virtual interfaces. Each public virtual interface needs
 * validation before the virtual interface can be created.
 * </p>
 * </li>
 * <li>
 * <p>
 * <b>Pending</b>: A virtual interface is in this state from the time that it is created until the virtual interface is
 * ready to forward traffic.
 * </p>
 * </li>
 * <li>
 * <p>
 * <b>Available</b>: A virtual interface that is able to forward traffic.
 * </p>
 * </li>
 * <li>
 * <p>
 * <b>Down</b>: A virtual interface that is BGP down.
 * </p>
 * </li>
 * <li>
 * <p>
 * <b>Deleting</b>: A virtual interface is in this state immediately after calling <a>DeleteVirtualInterface</a> until
 * it can no longer forward traffic.
 * </p>
 * </li>
 * <li>
 * <p>
 * <b>Deleted</b>: A virtual interface that cannot forward traffic.
 * </p>
 * </li>
 * <li>
 * <p>
 * <b>Rejected</b>: The virtual interface owner has declined creation of the virtual interface. If a virtual interface
 * in the 'Confirming' state is deleted by the virtual interface owner, the virtual interface will enter the 'Rejected'
 * state.
