We recently made changes in Havana to ensure that router configurations
are applied in order.  I will add that fix to the Grizzly backport list.

Title:
  L3 losing router interfaces

Status in OpenStack Neutron (virtual network service):
  Won't Fix

Bug description:
  I am seeing intermittent failures in adding interface to a router in
  Grizzly stable Ubuntu KVM OVS environment. Sometimes a router created
  with two interfaces ends up with only one interface. Looking through
  the logs it appears that execution of functionality is out-of-order
  than expected.  The sequence of commands is a) Create router, b) Add
  first interface c) Add second interface. From the logs it looks like
  the l3 first adds two interfaces and then deletes the second interface
  as if it executed the commands in the order of a), c) , b). Here is an
  extract of  relevant log entries:
