VN2: ctest-vn2-46567432 , 140.190.102.0/24, UUID d6ca1aa4-b9d3-4dc6-9b3c-05726ceb09e5 has VM ctest-vn2-vm1-53970969, 5ea78094-3258-4fc5-8d93-adca81f26e95(on nodei10) , with IP 140.190.102.3

A router was created and these two VNs were attached to the router at this time

2017-09-09 11:22:53,321 - INFO - Adding interface with subnet_id b3f3959a-6a5f-4e5f-b47e-604b5755e00f, port_id None to router 0725c70b-a7a9-4269-b94f-75e1bc294e6f

During the test , Pings between VMs failed till 11:24: and gave up.. When I logged in and I started to ping between VMs, it was failing until 11:39: and started passing from then on

From the flow logs, it was failing till 11:39 due to ‘No route for Dst-IP’ … and looks like the route got added then, after which things were fine.
The Ksync-Route, ControllerRxRouteXmppMessage1, Flow traces are in http://10.204.216.50/Docs/bugs/#
Gcores of control-node and agent of nodel1 are at http://10.204.216.50/Docs/bugs/#
