Hi, I am running into an issue which sounds pretty basic, probably I might be missing something.
Using, OVS: 2.9.0: 1. Created a mininet instance using: mn --topo single,3 2. Converted switch s1 to userspace switch and executed following commands: # Delete controller ovs-vsctl del-controller s1 #Convert s1 to userspace switch ovs-vsctl set Bridge s1 datapath_type=netdev # Add a VxLAN interface ovs-vsctl add-port s1 vxlan -- set Interface vxlan type=vxlan \ options:key=5 options:local_ip=1.1.1.1 options:remote_ip=1.1.1.2 ofport_request=10 # Add a Flow to pick any packet coming in on port 1(s1-eth1) egress out of vlan port ovs-ofctl add-flow s1 "table=0,in_port=1 actions=output:10" # Configure s1-eth3 to be the interface which connects to 1.1.1.0/24 ifconfig s1-eth3 1.1.1.1 arp -s 1.1.1.2 00:00:01:00:00:01 3. Now, I started ping h1 to h2 via mininet CLI. I expected to see VxLAN tagged packets on s1-eth3. But I do not. When I do ofproto/trace I see an error appears, "native tunnel routing failed" root@mininet:~# ovs-ofctl dump-flows s1 cookie=0x0, duration=197.045s, table=0, n_packets=3, n_bytes=210, in_port="s1-eth1" actions=output:vxlan root@mininet:~# ovs-appctl ofproto/trace s1 in_port=1,dl_dst=00:01:02:03:04:05 Flow: in_port=1,vlan_tci=0x0000,dl_src=00:00:00:00:00:00,dl_dst=00:01:02:03:04:05,dl_type=0x0000 bridge("s1") ------------ 0. in_port=1, priority 32768 output:10 -> output to native tunnel >> native tunnel routing failed Final flow: unchanged Megaflow: recirc_id=0,eth,in_port=1,dl_type=0x0000 Datapath actions: drop root@mininet:~# ovs-appctl ovs/route/lookup 1.1.1.2 src 1.1.1.1 gateway :: dev s1-eth3 Question is: Is there anything extra I need to configure if the switch were to use userspace datapath? Or what I am seeing is a bug? If I do the same configuration on kernel datapath mode(everything except the step which changes bridge datapath type), I see VxLAN packets on s1-eth3.
