2016-06-10 Thread Murali R
Adding another point to the thread. Per earlier John McDowell's suggestion if I disable port security for each of the ports involved, I get the traffic through as needed. But to be more elegant (and secure) I am trying to create ACL override specifically for this specific flows added. -Murali >

Andy Zhou spent some time last week investigating etcd 3.0 as a possible database target for OVN. Based on some of what he found out, and a little digging of my own, here's a summary of my thoughts on it in the format used previously for http://openvswitch.org/pipermail/dev/2016-March/067479.html:

Re: [ovs-discuss] MTU considerations for OVN

I think that if we come up with a good overall design, it should be able to handle different MTUs without needing to special case them - after all, we're already talking about 2 different MTUs (encapsulated and not) - so I don't think that having more would really make a significant difference.
