Question

我构建了一个简单的mininet拓扑，其中两个主机连接到交换机，由运行forwarding.L2_learning组件的远程控制器pox控制。这很好用ping一切都很好。

现在我用两个主机和两个交换机更改拓扑，每个主机连接到交换机，两个交换机都连接到运行相同组件的远程pox控制器（forwarding.L2_learning）。

但这次pingall无法正常工作!!我是mininet和pox的新手。

用于创建mininet拓扑的python脚本位于

我假设控制器在localhost上运行，但你应该替换

ip='0.0.0.0'

带

c0=net.addController(name='c0',
                      controller=RemoteController,
                      ip='127.0.0.1',
                      protocol='tcp',
                      port=6633)

并替换

net.addLink(h1, s2)

带

net.addLink(s1, s2)
