Routing connectors and listeners are automatically replicated to the
STANDBY instance. Routing listeners contain additional attributes
port2 for the 2nd HA instance.
It is recommended to define routing connectors at SwiftMQ HA Router instead of listeners. In this case, no configuration change is necessary at other routers in a Federated Router Network. If that is not possible, connecting routers must have an additional routing connector to the 2nd HA instance. If the first routing connection fails, the router will automatically connect with the other connector.
