It work for me because I have a two stage process where I first do routing, then I do OVS. It goes like : eth0 -> routing -> br0 -> OVS -> VxLAN -> eth1 Some config : echo 1 > /proc/sys/net/ipv4/ip_forward echo 1 > /proc/sys/net/ipv6/conf/all/forwarding ./ovs-vsctl add-br br52 ifconfig br52 10.1.1.2 netmask 255.255.255.0 ./ovs-vsctl add-port br52 vx1 -- set interface vx1 type=vxlan options:remote_ip=10.0.0.2 options:key=flow ./ovs-ofctl add-flow tcp:127.0.0.1:6634 "priority=32771,idle_timeout=0,in_port=local,pkt_mark=2,ip,ip_dst=10.10.10.0/255.255.255.0,action=set_field:0->tun_id,output:1" ip route add 10.10.10.0/24 via 10.1.1.2 ip -6 route add fd00:10::/64 dev br52 via fd00:1:1::2 iptables -t mangle -A PREROUTING -p tcp -m tcp --tcp-option XX -j MARK --set-mark 2 ip6tables -t mangle -A PREROUTING -p tcp -m tcp --tcp-option XX -j MARK --set-mark 2 Good luck...

Re: [ovs-discuss] Lost in translation! OFP to DPDK datapath OVS actions?
Actions that just set fields don't emit ODP actions to do that immediately because controllers often change fields multiple times between outputs, so that it would be wasteful to emit the changes multiple times. Instead, at the time of emitting an output (or other visible side effect), OVS emits all changes to fields in one group. On Sat, Jan 13, 2018 at 09:11:50AM +0100, Alan Kayahan wrote: > Indeed.

Re: [ovs-discuss] Windows test: 1077. ofproto-dpif.at:1663: testing ofproto-dpif - controller action without megaflows
Certainly these are odd results showing that on Windows an extra packet passes through the rate limiter. Do you have any leads on a possible solution? Does timing work somehow different on Windows?
