Public bug reported:
ENV:
stable/mitaka
How to reproduce:
1. create a HA router
neutron router-create --ha True --distributed False test1
2. set the HA router gateway with more than one IP
neutron router-gateway-set --fixed-ip ip_address=172.16.5.110 --fixed-ip
ip_address=172.16.5.111 test1 public
3. reset (update) the HA router gateway IP with a lower IP address
neutron router-gateway-set --fixed-ip ip_address=172.16.5.109 --fixed-ip
ip_address=172.16.5.110 test1 public
172.16.5.109 is lower that 172.16.5.110, then l3 agent will get the
following trace:
