Ganesh Murthy updated DISPATCH-2256:
------------------------------------
Fix Version/s: Backlog
(was: 1.19.0)
> edge router fallback links and addresses incorrect on interior failover
> -----------------------------------------------------------------------
>
> Key: DISPATCH-2256
> URL: https://issues.apache.org/jira/browse/DISPATCH-2256
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Router Node
> Affects Versions: 1.17.0
> Reporter: Ken Giusti
> Assignee: Ken Giusti
> Priority: Major
> Fix For: Backlog
>
>
> Scenario:
> Configure an edge router with two separate interior connectors - one for
> router A and a standby for router B.
> Configure a route-container listener for a broker on the edge router. Assign
> two fallback destination autolinks (1 in, 1 out) to the route container for
> address "foo".
> Start just the edge router:
> * no links are active (expected).
> * mgmt query for addresses show two "foo" addresses present:
> ** MFfoo - the fallback address (no subscribers)
> ** M0foo - the primary address (no subscribers)
> Now startup the broker and after the connection to the broker:
> * On the edge router:
> ** links:
> *** id 5, out link to broker, owning address MFfoo
> *** id 6, in link from broker, owning address M0foo
> ** addresses:
> *** MFfoo - one local subscriber
> *** M0foo - no subscribers
> Now start router A. Router A has been configured with an edge listener
> connection. There is no inter-router connection configured for router B!
> Once the connection is established:
> * On the edge router:
> ** links:
> *** the two broker links (see above)
> *** id 10, in link from router A, owning address MFfoo
> *** id 11, out link to router A for M0foo
> ** addresses:
> *** MFfoo - one local subscriber
> *** M0foo - no subscribers
> * On Router A:
> ** links:
> *** id 6, out link to edge, owning address MFfoo
> *** id 7, in link from edge, owning address M0foo
> ** addresses:
> *** MFfoo - one local subscriber
> *** M0foo - no subscribers
> Now start router B, wait for the edge to establish a connection to it. Since
> B is a standby interior for the edge there are no 'foo' related links or
> addresses on B as expected. Remember router A and B are not directly
> connected.
>
> Fail router A. Wait for the edge to re-establish its proxy links to router
> B. The following links/addresses related to foo are now:
> * On the edge router:
> ** links:
> *** the two broker links
> *** id 20, in link from router B, owning address MFfoo
> ** addresses:
> *** MFfoo - one local subscriber
> *** M0foo - no subscribers
> * On Router B:
> ** links:
> *** id 6, out link to edge, owning address MFfoo
> ** addresses:
> *** MFfoo - one local subscriber
> From the above we can see that after the failover to router B the edge router
> does not re-establish an outgoing link (subscription) for M0foo as it did
> when connected to router A.
