Description
Summary:
ARP Responder Flows are not removed from compute hosts when an instance is deleted. When an instance is attached the ARP Responder Flows are added to the OVS on both controller and compute hosts. When the instance is the deleted the ARP Responder Flows are removed from the controller but not from the compute hosts.
We expect the ARP Responder Flows to be removed from the compute hosts also.
The consequence of this is that if the instance is relaunched with the same ip address and another instance tries to reach it the action will fail as the old mac address of the instance is still in the ARP Responder flows.
This was seen on:
Boron 1.3.0.
Open vSwitch 2.4.1
OpenFlow versions 0x1:0x4
Kernel:
