Thanks again for your feedback.
I've checked your another post
http://assafmuller.com/2014/02/23/ml2-address-population/
Then added entries to ml2_conf.ini on all compute nodes :-
[agent]
l2_population = True
Afterwards updated ovs_neutron_plugin.ini on all nodes with :-
l2_population = True
enable_distributed_routing = True
arp_responder = True
Then restarted all nodes and VXLAN tunnels came up as expected.
Update done to ml2_conf.ini files seems to be important for neutron-openvswitch-agent.
DVR is also working as expected.
Boris.

I'm not sure what you're asking. Everything you described seems like it's
working as intended.Is anything not working, any specific questions?
By the way, check out my series of blog posts on DVR here, it may
help:http://assafmuller.com/2015/04/15/distributed-virtual-routing-overvi...

Per
http://www.linux.com/community/blogs/133-general-linux/850749-rdo-juno-dv...
However, to have VXLAN tunnels alive I was forced to set on each node
l2population,enable_distributed_routing,arp_responder to False.
[root@ip-192-169-142-147 openvswitch]# cat ovs_neutron_plugin.ini | grep -v ^#| grep -v
^$
[ovs]
enable_tunneling = True
integration_bridge = br-int
tunnel_bridge = br-tun
local_ip =10.0.0.147
bridge_mappings =physnet1:br-ex
[agent]
polling_interval = 2
tunnel_types =vxlan
vxlan_udp_port =4789
l2population = False
enable_distributed_routing = False
arp_responder = False
[securitygroup]
firewall_driver = neutron.agent.linux.iptables_firewall.OVSHybridIptablesFirewallDriver
So, I was expecting all traffic to go via br-ex on Controller 192.169.142.127.
However, when I created as admin distributed router belongs to demo.
As demo tenant attached public and private networks to router.
Created VM (F22) and assigned floating IP no VM.
On Compute Node 192.169.142.147 appeared two namespaces :-
[root@ip-192-169-142-147 ~]# ip netns
fip-a33f05a2-f6ca-4dd9-ba84-1b9e2f3f256d
qrouter-1ca178ff-2ee1-4f40-a65a-fbc590dc18a4
Then I logged into Fedora VM via floating IP and started download of
CentOS-7-x86_64-Everything-1503-01.iso (7.5 GB) image via wget.
[root@vf22devs01 ~]# wget

Protocol bellow clearly shows that traffic was coming via br-ex on Compute Node
Looks like if Compute nodes are running required services, ml2_conf.ini and
metadata_agent.ini
are replicated as required and admin creates:-
# source keystonerc_admin
# neutron router-create RouterDemo --distributed True --tenant-id demo-tenants-id
DVR will work with l2population, arp_responder, enable_distributed_routing set to False
across all landscape.
