> Prepare Routing Protocol for Backward Compatibility
> ---------------------------------------------------
>
> Key: DISPATCH-1582
> URL: https://issues.apache.org/jira/browse/DISPATCH-1582
> Project: Qpid Dispatch
> Issue Type: Improvement
> Components: Routing Engine
> Reporter: Ted Ross
> Assignee: Ted Ross
> Priority: Minor
> Fix For: 1.11.0
>
>
> In anticipation of moving to routing protocol version 2 (we're currently on 1), there are a few changes needed to make it easy for version 2 to be backward compatible to version 1. This Jira will track those changes.
> The proposed change is to ensure that a version 1 router ignores version >1 messages, issuing a low-volume warning log when one is received. This way, a version 2 router can send both versions or send targeted versions based on its knowledge of peer routers protocol versions.
