Han, thanks for suggestions. Yes I had tried all that. Controller means node running northd. The issue is databases are all looking ok and so are tunnels they have tunnel address correct on both sides. But the overlay network created is not reachable in remote node. Host routing is not applicable here because the network is extended through tunnel. I looked at ovs-appctl routes and the 10.0.0.0/24 is not in there. Should we manually add the route thru appctl? Or how to debug the routing from remote node works? Or any other host route setup is needed? For instance I can ping q-router interface from remote node. But not sure why network is not available through tunnel.
