And follow this guide[2] to install OVS-DPDK. The OVS version is 2.6.0. The DPDK version is dpdk-16.07. My local Linux environment is CentOS 7.1.1503 and the kernel version is 3.10.0-327.el7.x86_64. I'm a little confused about that how packet forward from br-phy1 to br-int? In kernel version ovs, packet from one bridge to another bridge mush connected by veth or ovs patch [Sugesh] Though the br-phy1 and br-int are not directly connected, the ip address assigned to br-phy1 belongs to the same subnet of tunnel endpoint. Having said that, ovs route the tunneled packets after encapsulation to bridge interface(in the same subnet) and vice versa. You can verify the route and arp entries populated in OVS using the following command. ovs-appctl tnl/arp/show ovs-appctl ovs/route/show It is kind of similar to what happens in kernel tunnel interface. After the encapsulation, kernel has to find out the corresponding interface to xmit the tunnel traffic which is determined by the interface IP. Hope this helps But in dpdk ovs vxlan config, there is no ovs patch .And pakcet not forward through br-phy1 to br-int How the packet forward from br-phy1 to br-int? Hope to you reply ;-) Thx.
