Restack/new compute node VM doesn’t communicated north-south traffic

Build#: Lithium-SR1 Build
Openstack: stable/kilo
ODL config (on etc/custom.properties)
===========
ovsdb.of.version=1.3
ovsdb.l3.fwd.enabled=yes

local.conf snip
=======
enable_plugin networking-odl https://github.com/stackforge/networking-odl stable/kilo
Q_PLUGIN=ml2
ENABLE_TENANT_TUNNELS=True
Q_ML2_TENANT_NETWORK_TYPE=vxlan

Openstack setup
=================
eth0 => Mgmt Network eth1=> Data Network eth3 => External Network

Scenario
==========
1.Create Network 32.1.1.0/24 and External Network as 5.1.1.0/24
2.Create Router and assign GW as 5.1.1.0/24 as external network and associate 32.1.1.0/24
3.Spawned VM1 on Compute Node1 IP address as 31.1.1.3 and Floating IP Address as 5.1.1.2
4.VM1 will communicate with External Network GateWay 5.1.1.1
5.Stack the new compute node and spawn VM2 assign ip address 31.1.1.4 and floating IP address 5.1.1.3
6.VM2 unable to communicated with External Network (i.e North-South).However VM1 and VM2 manage to communicate using local network (i.e 31.1.1.3 to 31.1.1.4)

Observation:
=========
OF-Flow entries of Router Interface missing on restack/new compute node br-int interface.
