[Openstack] packets not reaching br-tun

Hi all,

I am doing a openstack juno setup using packstack. 
1(controller+neutron), other two compute nodes. My VM packets are 
reaching br-int but not br-tun when I cpatured packets using tcpdump. 
Because of this the VM is not getting IP (which I manually configured 
using ifconfig for testing the network).

Please help me resolve the problem.

ovs-vsctl show on compute node:
