qpid-route does not properly consider src-local when matching bridges. The practical upshot of this is that it may consider routes to be duplicates when they are in fact not.
Take the following (slightly contrived) scenario:
Brokers A and B both have queues named "test.queue" and default exchanges named "amq.direct".
We would like a queue route to pull messages from B:test.queue to A:amq.direct and a src_local route to push messages from A:test.queue to B:amq.direct. Since qpid-route does not consider the src-local flag, it will regard the second route to be a duplicate and will not allow it to be added.
