------------------------------------
Fix Version/s: (was: 1.9.0)
> Link (address) priority is ignored by the second hop router
> -----------------------------------------------------------
>
> Key: DISPATCH-1368
> URL: https://issues.apache.org/jira/browse/DISPATCH-1368
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Router Node
> Affects Versions: 1.8.0
> Reporter: Ken Giusti
> Assignee: michael goulish
> Priority: Major
>
> Address-based priority is only enforced on the egress of the first hop router.
> In a 3 router linear network:
> Sender --> Router A --> Router B --> Router C --> Receiver
> Message delivery is properly sent via the inter-router links between Router A and Router B.
> However, those messages are all forwarded on the default priority (4) between router B and C.
> [C --> Receiver is fine - priority doesn't apply to egress endpoint links]
> The expectation is that the message priority is honored across all inter-router links.
> [Reproducer|https://github.com/kgiusti/dispatch/tree/DISPATCH-1368-reproducer]
> Build the router, then run the priority test (ctest -VV -R priority).
> Then grep for "DELIVERIES" in the log files:
> grep "DELIVERIES" tests/system_test.dir/system_tests_priority/CongestionTests/setUpClass/*.log
