From 18b6f717483a835fb98de9f0df6c724df9324e78 Mon Sep 17 00:00:00 2001 From: wenxu Date: Thu, 28 Mar 2019 12:43:23 +0800 Subject: openvswitch: Make metadata_dst tunnel work in IP_TUNNEL_INFO_BRIDGE mode There is currently no support for the multicast/broadcast aspects of VXLAN in ovs. In the datapath flow the tun_dst must specific. But in the IP_TUNNEL_INFO_BRIDGE mode the tun_dst can not be specific. And the packet can forward through the fdb table of vxlan devcice. In this mode the broadcast/multicast packet can be sent through the following ways in ovs. ovs-vsctl add-port br0 vxlan -- set in vxlan type=vxlan \ options:key=1000 options:remote_ip=flow ovs-ofctl add-flow br0 in_port=LOCAL,dl_dst=ff:ff:ff:ff:ff:ff, \ action=output:vxlan bridge fdb append ff:ff:ff:ff:ff:ff dev vxlan_sys_4789 dst 172.168.0.1 \ src_vni 1000 vni 1000 self bridge fdb append ff:ff:ff:ff:ff:ff dev vxlan_sys_4789 dst 172.168.0.2 \ src_vni 1000 vni 1000 self Signed-off-by: wenxu Acked-by: Pravin B Shelar Signed-off-by: David S.
