I recently added a Neutron RFE [1] that proposes a new extension called Pluggable Backend Association Mappings (PBAM). This admin-based extension allows consumers to view Neutron / backend resource mappings, quickly identify mappings that are out of sync and remediate them. If this sounds interesting to you, please join us on the RFE [1] for a discussion and see [2] for a video demo and [3] for the PoC repo that contains detailed documentation about the extension. Thanks [1] https://bugs.launchpad.net/neutron/+bug/1563538 [2] https://www.youtube.com/watch?v=qAY8U8vgbzc [3] https://github.com/bodenr/neutron/tree/feature/pbam
