如何正确连接遥控器POX和minin

Question

我构建了一个简单的微型网络拓扑，两台主机连接到交换机，交换机由运行forwarding.L2_学习组件的远程控制器pox控制。这工作好平都好。在

现在我改变了拓扑结构，两台主机和两台交换机分别连接到一台交换机，两台交换机都连接到运行同一组件的远程pox控制器（forwarding.L2_learning）。在

但这一次pingall不起作用了！！我对迷你网和痘不太熟悉。在

下面是用于创建迷你网拓扑的python脚本

#!/usr/bin/python

from mininet.node import CPULimitedHost, Host, Node

def myNetwork():
    net = Mininet(topo=None,
                  build=False,
                  ipBase='10.0.0.0/8')

    info('*** Adding controller\n')
    c0 = net.addController(name='c0',
                           controller=RemoteController,
                           ip='0.0.0.0',
                           protocol='tcp',
                           port=6633)

    info('*** Add switches\n')
    s1 = net.addSwitch('s1', cls=OVSKernelSwitch)
    s2 = net.addSwitch('s2', cls=OVSKernelSwitch)

    info('*** Add hosts\n')
    h1 = net.addHost('h1', cls=Host, ip='10.0.0.1', defaultRoute=None)
    h2 = net.addHost('h2', cls=Host, ip='10.0.0.2', defaultRoute=None)

    info('*** Add links\n')
    net.addLink(h1, s1)
    net.addLink(h2, s2)
    net.addLink(h1, s2)

    info('*** Starting network\n')
    net.build()

    info('*** Starting controllers\n')
    for controller in net.controllers:
        controller.start()

    info('*** Starting switches\n')
    net.get('s1').start([c0])
    net.get('s2').start([c0])

    info('*** Post configure switches and hosts\n')
    net.pingAll()
    net.stop()


if __name__ == '__main__':
    setLogLevel('info')
    myNetwork()

Answer 1

我假设控制器在本地主机上运行，但是您应该替换

ip='0.0.0.0'

与

^{pr2}$

并替换

net.addLink(h1, s2)

与

net.addLink(s1, s2)
