話不多說，直接上拓撲：

我這裏是用主機h1 （10.0.0.1）ping 主機h2(10.0.0.2)

1.添加VLAN標簽

v1:
sudo ovs-ofctl add-flow m1-s1 in_port=1,actions=mod_vlan_vid:123,output:4
v2:
sudo ovs-ofctl add-flow m1-s2 in_port=1,dl_vlan=123,action=output:2
v3:
sudo ovs-ofctl add-flow m1-s3 in_port=2,dl_vlan=123,actions=strip_vlan,output:1

2.添加MPLS標簽

註意：ping是先用arp協議查看目標ip的mac地址，在發送icmp數據包，所以加標簽完了去標簽的時候要註意區分包類型！

V1
sudo ovs-ofctl add-flow -O OpenFlow13 m1-s1 icmp,in_port=1,actions=push_mpls:0x8847,set_field:123-\>mpls_label,output:4
sudo ovs-ofctl add-flow -O OpenFlow13 m1-s1 arp,in_port=1,actions=push_mpls:0x8847,set_field:124-\>mpls_label,output:4
 

V2
//改為ip協議 ，支持icmp
sudo ovs-ofctl add-flow -O OpenFlow13 m1-s2 mpls,in_port=1,mpls_label=123,actions=pop_mpls:0x0800,output:2
sudo ovs-ofctl add-flow -O OpenFlow13 m1-s2 mpls,in_port=1,mpls_label=124,actions=pop_mpls:0x0806,output:2
V3
sudo ovs-ofctl add-flow m1-s3 in_port=2,actions=output:1

附加：OVS操作cmd:

查看交換機流表
sudo ovs-ofctl dump-flows br0 "in_port=1"

刪除指定交換機流表
sudo ovs-ofctl del-flows m1-s2

3.結果：

利用OVS+FLOODLIGHT，為數據表添加VLAN_ID和MPLS
