[ovs-discuss] OpenFlow “select” group

Hi all, I know that Open vSwitch 2.4 and later + OpenFlow 1.4, by default, hashes some headers fields to choose a bucket in a select group. What if I want to change the way this is being done? What would be the right approach to accomplish this? (i.e distribute packets among buckets using some ki

Re: [ovs-discuss] Thoughts on gratuitous ARP

Also note that you really need this kernel patch series [1] to have ARP cache to work in all cases. It's nice to have both REQUESTs and REPLYs sent but it won't help in all cases. The series guarantees that you don't get in an indefinite loop with stale MAC data as described in [2]. Note that the s

Re: [ovs-discuss] Thoughts on gratuitous ARP

In neutron reference implementation, initially we were sending ARP REPLYs only that didn't work with existing kernels in specific scenarios. We added ARP REQUESTs (while continuing sending REPLYs). I think it makes sense to send both types because some nodes may e.g. know about REPLYs and not REQUE

[ovs-discuss] What is a l2 pkt microflow

Hello I understand that microflow kernel cache entries consist of full set of header keys. What about a l2 pkt e.g cfm pkt. What are the hash keys for cfm pkt in the single microflow table? Thank you in advance Sara ___ discuss mailing list disc...@openvs

I have a patch ready for ovn to send REPLIES additionally to the requests so, if we believe it makes sense, I can send it to the dev list. On Thu, Nov 16, 2017 at 4:18 PM, Ihar Hrachyshka wrote: > In neutron reference implementation, initially we were sending ARP > REPLYs only that didn't work w

Re: [ovs-discuss] Thoughts on gratuitous ARP

Sorry, it's the other way around. REQUEST is what neutron reference solution started using (ANSWER was the previous type of ARP packet which was leading to issues with the buggy kernels). Since ovn-controller emits gratuitous ARPs as broadcast ARP requests, that should work. @Ihar, if you can co

[ovs-discuss] kubernetes - kubeadm problem with watcher

Ok, I got to reproduce the error I had yesterday. Here's the path :   1- one vm with centos 7   2- install kubeadm v1.8.3   3- kubeadm init   4- install openvswitch (v2.8.1)   5- follow the instruction of set-master.sh   6- ln -s /etc/kubernetes/pki/ca.crt /etc/openvswitch/k8s-ca.crt   7-
