Public bug reported:

======= Problem Description ======

    I installed a devstack in my local environment. All the code from
master branch. After the installation, I have to show you some problems
which I met.

    Neutron server log at http://paste.openstack.org/show/587158/.


======= How to reproduce ======= 

    First of all, I create an external network by this command " neutron
net-create public --router:external=True --provider:network_type=flat
--provider:physical_network=public ".

    Secondly, I create a subnet with " subnet_type " by this command "
neutron subnet-create [net-id] 20.20.20.0/24 --service-types list=true
network:router_gateway ".

    At last, I create a router and setting this router's gateway by this
command " neutron router-gateway-set [router-id] [net-id]".

    Exception happens in Neutron Server, it says "
HostNotCompatibleWithFixedIps: Host devstack is not connected to a
segment where the existing fixed_ips on port 0f38ba01-8dd0-43de-
92e3-b294bd4ebed8 will function given the routed network topology. ".


   I upload all the network and subnets info at here [1]. Detail exception at here [2].
