commit b45fd35e3f4a2aaacc7a22faafd00b7350e4f398 Author: Dongcan Ye <[email protected]> Date: Mon Nov 14 17:35:20 2016 +0800 Remove floatingip address ignores ha_state We both enables router_distributed and l3_ha in server side, and configures L3 agent node as dvr_snat in compute nodes. HA router removing floatingip address only in master node, and dvr local router only remove FIP rule. This will cause RTNETLINK error if we operates floatingip "associate --> disassociate --> reassociate". This patch removes floatingip address whether router's ha_state is master or backup. Another solution is adding remove_floating_ip in dvr_edge_router.

Engineering Team, which is subscribed to neutron. https://bugs.launchpad.net/bugs/1641535 Title: FIP failed to remove in router's standby node Status in neutron: Fix Released Bug description: ENV ==================== 1. Server side: enable router_distributed and l3_ha 2. Agent side: all L3 agent mode is dvr_snat (include network nodes and compute nodes) How to reprocude: ================= associate floatingip --> disassociate floatingip --> reassociate floatingip We hit trace info in l3 agent: http://paste.openstack.org/show/589071/ Analysis ========== When we processing floatingip (In the situation router's attribute is ha + dvr), in ha_router we only remove floatingip if ha state is 'master'[1], and in dvr_local_router we remove it's related IP rule. Then we reassociate floatingip, it will hit RTNETLINK error. Because we had already delete the realted IP rule.
