3. deploy a webserver pod on the windows node 
4. deploy a client pod on a linux node

Comment 1 Jacob Tanenbaum 2020-04-23 19:35:50 UTC
along with https://github.com/openshift/cluster-network-operator/pull/604 should fully fix current windows networking issues

Comment 2 zhaozhanqi 2020-04-24 03:06:17 UTC
move the status to 'post' for now since the PR still in open

Comment 6 Dan Williams 2020-04-24 14:16:56 UTC
If you run a couple pods on the node, then "oc rsh" to the ovnkube-node pod, then "ovs-ofctl dump-flows br-ext" and all local pods have a flow in table=10 we're good.
