Informing other brokers about the stream

When a stream is first referenced by a publisher or subscriber (for example, when a registration request is sent to the broker's control queue) the broker informs its neighbors that the stream exists. If the neighboring brokers also have a queue defined for the stream (or can create one using SYSTEM.BROKER.MODEL.STREAM), they also recognize the stream and pass information about it to their neighbors.

If a broker that is told about the stream does not have a queue for the stream and does not have the SYSTEM.BROKER.MODEL.STREAM, it does not pass information about the stream to its neighbors.
