【问题描述】：
我有以下带有 ODL 控制器的线性 SDN 架构：
Host1 -- ZodiacFX1 -- ZodiacFX2 --- Host2
我使用 2 台笔记本电脑作为主机和 2 个 ZodiacFX openflow 交换机。
我希望 ZodiacFX1 将 MPLS 标签推送到从 Host1 接收到的所有 IP 数据包，并且 ZodiacFX2 弹出 MPLS 标签并将 IP 数据包发送到 Host2。
我为 ZodiacFX1 上的 MPLS 推送添加了一个流，我可以在 ZodiacFX1 以及 ODL 的操作数据存储中看到该流处于活动状态。但是如果我 ping h1->h2 没有推送。
流程是这样的：
注意：（Host1连接到ZodiacFX1的端口1，ZodiacFX1的端口2连接到ZodiacFX2的端口1。）

我也可以在 Zodiac 控制台界面中看到：
Flow 6
Match:
In Port: 1
ETH Type: IPv4
Attributes:
Table ID: 2 Cookie:0x191
Priority: 8 Duration: 247 secs
Hard Timeout: 0 secs Idle Timeout: 0 secs
Byte Count: 0 Packet Count: 0
Last Match: 00:04:07
Instructions:
Apply Actions:
Push MPLS tag
Set MPLS Label: 27
Output Port: 2
可能是什么问题？我认为主要问题是在这种情况下 Zodiac 遵循此流程，我也尝试了优先级为 0 的流程并且没有 MPLS 推送。
Flow 5
Match:
In Port: 1
