commit ee7660f593f0f997fff457021b3d5feb5c71906d Author: LIU Yulong <[email protected]> Date: Thu Sep 20 21:30:09 2018 +0800 Install centralized floating IP nat rules to all ha nodes For L3 DVR HA router, the centralized floating IP nat rules are not installed in every HA node snat namespace. So, install the rules to all the router snat-namespace on every scheduled HA router host. Closes-Bug: #1793527 Change-Id: I08132510b3ed374a3f85146498f3624a103873d7 ** Changed in: neutron Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo!

How to reproduce: 1. create DVR_HA router connecting user private network and public external network 2. create a VM in dvr_no_external compute in private network 3. create floating IP and associate to the VM port Then, only in the `master` node snat-namespace has the iptables rules. Even the DVR_HA router has state change(backup -> master, master -> backup), the iptables rules are still not re-created in the new `master` snat-namespace. All centralized floating IPs can be unreachable after a HA router state change.
