Gary Tully resolved AMQ-4607.
-----------------------------
Resolution: Fixed
fix in http://svn.apache.org/r1497716
networkTTL sets both consumerTTL and messageTTL
a value of -1 denotes infinite hops.
In a mesh, use consumerTTL=1, messageTTL=-1 to allow consumers to bounce around
the mesh and messages to follow demand.
In a linear topology use networkTTL == length of network (as before)
> network connectors - new messageTTL and consumerTTL - split usage of
> networkTTL for mesh topology

> Project: ActiveMQ
> Issue Type: Improvement
> Components: Broker
> Affects Versions: 5.8.0

> Fix For: 5.9.0

>
> currently networkTTL in a networkConnector (default=1) means that a message
> can go one hop and demand (or info about a consumer) can go one hop.
> In a network (A<>B) messages and consumers can flow.
> In a linear network (A<>B<>C) networkTTL needs to be 2 for messages and
> consumers to flow two hops from A to C.
> In a mesh topology, (A<>B<>C<A>) a networkTTL=1 for consumers makes sense
> because there is at most one hop. However for messages, networkTTL > 1 is
> necessary if consumers need to hop around between brokers. Imagine a consumer
> on A which pulls messages to A from B, then the consumer moves to C, messages
> now need to hop again from A to C. This can repeat, essentially
> messageTTL(networkTTL) needs to be infinite.
> With consumerTTL > 1 in a mesh, managing demand for proxy (demand) consumers
> and proxy proxy consumers becomes very difficult.
