Hi all,
I am a newcomer to open vSwith, and am having some configuration
difficulties. In my experiment I'm trying to build an OpenFlow Ethernet
switch box from a PC running open vSwitch.
I am in the following situation:
- OVS and controller can see each other
- controller can see directly connected hosts (e.g. LLDP messages are being
flooded)
However when I try to ping from one host to another the following happens
(as observed on wireshark at the controller and each of the hosts:
- ARP request from host1 is sent to controller
- controller tells OVS to flood ARP request back
- host2 receives ARP request
- host2 replies to ARP request
-....
The ARP response from host2 is not being sent back to the controller.
The connection between the controller and OVS is via an interface which is
not part of the OVS bridge. As such I tried setting the connection mode to
out-of-band, but this did not make any noticeable difference.
# ovs-vsctl show

Any advise on how to correctly configure this set-up appreciated.
Thanks for your time,
Stuart.
