实验目的

在给定如上实验拓扑情况下，用vlan得到下列虚拟网段

h1--h4互通

h2--h5互通

h3--h6互通

其余主机间无法通信

实验步骤

1.创建以下拓扑（可采用任意方式）

from mininet.topo import Topo
 
class MyTopo( Topo ):
    "Simple topology example."
 
    def __init__( self ):
 
        # Initialize topology
        Topo.__init__( self )

        # add switches and hosts  
        sw1 = self.addSwitch(\'s1\')
        sw2 = self.addSwitch(\'s2\')

        h1 = self.addHost(\'h1\')
        h2 = self.addHost(\'h2\')
        h3 = self.addHost(\'h3\')
        h4 = self.addHost(\'h4\')
        h5 = self.addHost(\'h5\')
        h6 = self.addHost(\'h6\')

        # add links
        self.addLink(h1,sw1,1,1)
        self.addLink(h2,sw1,1,2)
        self.addLink(h3,sw1,1,3)
        self.addLink(sw1,sw2,4,4)
        self.addLink(h4,sw2,1,1)
        self.addLink(h5,sw2,1,2)
        self.addLink(h6,sw2,1,3)

topos = { \'mytopo\': ( lambda: MyTopo() ) }
