During the transition period, other gateways will republish GTS data to WIS2. These GTS to WIS2 gateways will publish via a designated ``centre-id``. To avoid an infinite loop of republication, it is essential that a WIS2 to GTS gateway does not subscribe to notification messages associated with the centre-id of a GTS to WIS2 gateway.
