Re: [ovs-discuss] OVN-k8s VLAN support
Thanks Numan,apparently ovn-k8s CNI does not support all the features of OVN.Will ask there thanks for your suggestion.

[ovs-discuss] OVN-k8s VLAN support
Hello, Can you please tell me if there is a plan to support VLAN aware interfaces for pods or is there a way to make VxLAN terminate on underlay devices with EvPN Type 2 enabled. Similar to https://github.com/kubeovn/kube-ovn/blob/master/docs/vlan.md [image: image.png] so that integration with existing infrastructure would be easier without a VxLAN gateway. ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
[ovs-discuss] OVN-k8s Project roadmap
Hello everybody, Is there a project roadmap page available for ovn-k8s? We are planning to use OVN-k8s replacing another CNI, being Telco there are some features that we rely on for advertising non HTTP/non SRIOV networks over VLAN that needs to be accessed directly. Today our VMs are running on Openstack with VLAN based networks that are reachable from provider edge networks. Is there a possibility or roadmap to support VLAN based networks apart from the current overlay tunnels.Another OVN project (i think OVN4NFV) has this supported already.

Thanks Guru. For some reason openstack was creating tap interfaces on compute with an MTU of 1500,where as for all other virtual/physical devices its 9000.After changing mtu of tap ,everything is good now.Thanks alot On Fri, Nov 3, 2017 at 11:30 PM, Guru Shetty wrote: > > > On 2 November 2017 at 13:07, kevin parrikar > wrote: > >> Hello All, >> I am running OVS 2.6.1 on Ubuntu 14.04 kernel 4.4.0-87-generic with >> Openstack Mitaka release with OVS firewall driver(contrack ) >> >> >> MTU is set to 9000 on both the physical nics and icmp is success with >> ping -Mdo -s 8000 flag >> how ever tcp and udp streams are too slow. >> >> > If you are using tunnels, reduce the MTU of the inner packet by the amount > of tunnel header. > > >> TCP >> >> iperf -c 192.168.111.202 >> >> Client connecting to 192.168.111.202, TCP port 5001 >> TCP window size: 92.6 KByte (default) >> >> [ 3] local 192.168.111.199 port 44228 connected with 192.168.111.202 >> port 5001 >> [ ID] Interval Transfer Bandwidth >> [ 3] 0.0-927.7 sec 175 KBytes 1.54 Kbits/sec >> >> UDP >> >> iperf -s -u >> >> Server listening on UDP port 5001 >> Receiving 1470 byte datagrams >> UDP buffer size: 122 KByte (default) >> >> [ 3] local 192.168.111.202 port 5001 connected with 192.168.111.199 port >> 45028 >> [ ID] Interval Transfer BandwidthJitter Lost/Total >> Datagrams >> [ 3] 0.0-10.0 sec 1.25 MBytes 1.05 Mbits/sec 0.086 ms0/ 893 >> (0%) >> >> Any idea where could be the issue. >> >> Regards, >> Kevin >> >> >> >> ___ >> discuss mailing list >> disc...@openvswitch.org >> https://mail.openvswitch.org/mailman/listinfo/ovs-discuss >> >> > ___ discuss mailing list disc...@openvswitch.org https://mail.openvswitch.org/mailman/listinfo/ovs-discuss
