Hi Bob, Hope you are doing good. I am looking into the following defect: https://bugs.launchpad.net/neutron/+bug/1224978 " *port binding on multi segment networks could lead to agent misconfiguration*" discussed in the ML2 meeting on 28th May 2014. It would be great if someone could provide document on How to enable Modular L2 Multi-Segemnt Network without using ToR switch. So that I can proceed further and reproduce the defect and try to fix it.
