[OVSDB-266] Instances are not reachable in Openstack when ODL used as cluster (using OFPlugin He design)

Wed, 10 Feb 2016 01:47:54 +0000

Created an ODL cluster with all instances running odl-ovsdb-openstack feature using the OpenFlow Plugin (He) design.

stacked up Openstack Control and Compute nodes, Then

i) created Network + instances
result: Instances do not have the IP, the discover fails

ii) Created router and added one more network and created instances
result: Same behavior

From early observations, the flow entries sem to be missing a lot of items in the chain.

These are the flow entries in control node.
