{{System A:}}

{{    green router}}
{{        5672 - normal listener}}
{{        20001 - inter-router listener}}

{{System B:}}

{{   blue router}}
{{        5672 - normal listener}}
{{        connector to green}}

{{   collectd router}}
{{        15672 - normal listener}}
{{        connector to green}}

{{Failing test:}}

{{   Start receiver 1 on A:5672  (green)}}
{{   Start receiver 2 on B:5672  (blue)}}
{{   Start sender on     B:15672 (collectd)}}

{{   Receivers have credit of 1000}}
{{   Senders send 500-byte payloads. And plenty of 'em.}}

{{Data path:}}
{{   messages received on collectd forwarded to green}}
{{   green receives interrouter; sends to local receiver, forwards to blue}}
{{   blue receives interrouter; sends to local receiver}}
