Public bug reported: 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.
