While I was at it, I noticed that the Neutron LBaaS requirements list LVS under the manner in which to support UDP.
https://wiki.openstack.org/wiki/Neutron/LBaaS/requirements So, looked for an LVS plug-in for Neutron LBaaS. I found one in progress for Juno (which may be too late for me)... Looking at the code, it seems to support HTTP/TCP/SSH, but I don't see UDP. Am I missing something? https://blueprints.launchpad.net/neutron/+spec/neutron-brocade-lbaas-driver On Mon, Jul 14, 2014 at 12:05 PM, Michael Klebanow <[email protected] > wrote: > Actually, rewind that second comment a moment.
