2019 SDN上機第6次做業

1.實驗拓撲

實驗拓撲

python腳本

from mininet.topo import Topo
class MyTopo(Topo):
    def __init__(self):
        Topo.__init__(self)
        h1 = self.addHost('h1')
        h2 = self.addHost('h2')
        h3 = self.addHost('h3')
        h4 = self.addHost('h4')
        h5 = self.addHost('h5')
        h6 = self.addHost('h6')
        s1 = self.addSwitch('s1')
        s2 = self.addSwitch('s2')
        self.addLink(h1, s1, 1, 1)
        self.addLink(h2, s1, 1, 2)
        self.addLink(h3, s1, 1, 3)
        self.addLink(s1, s2, 4, 4)
        self.addLink(h4, s2, 1, 1)
        self.addLink(h5, s2, 1, 2)
        self.addLink(h6, s2, 1, 3)
topos = {'mytopo': (lambda: MyTopo())}

輸入命令執行文件建立拓撲

sudo mn --custom ex.py --topo mytopo --controller=remote,ip=127.0.0.1,port=6633 --switch ovsk,protocols=OpenFlow13
