使用mininet建構一個簡單的路由實驗
網路拓撲結構如下:
#Mininet的拓樸定義程式碼:
from mininet.topo import Topo class Router_Topo(Topo): def __init__(self): "Create P2P topology." # Initialize topology Topo.__init__(self) # Add hosts and switches H1 = self.addHost('h1') H2 = self.addHost('h2') H3 = self.addHost('h3') S1 = self.addSwitch('s1') S2 = self.addSwitch('s2') # Add links self.addLink(H1, S1) self.addLink(H2, S1) self.addLink(H2, S2) self.addLink(H3, S2) topos = { 'router': (lambda: Router_Topo()) }
利用上面的腳本產生網路拓撲:
sudo mn --custom /home/mininet/Router.py --topo router mininet> net h1 h1-eth0:s1-eth1 h2 h2-eth0:s1-eth2 h2-eth1:s2-eth1 h3 h3-eth0:s2-eth2 s1 lo: s1-eth1:h1-eth0 s1-eth2:h2-eth0 s2 lo: s2-eth1:h2-eth1 s2-eth2:h3-eth0
為節點設定路由功能:
mininet> h1 ifconfig h1-eth0 192.168.12.1 netmask 255.255.255.0 mininet> h2 ifconfig h2-eth0 192.168.12.2 netmask 255.255.255.0 mininet> h2 ifconfig h2-eth1 192.168.23.2 netmask 255.255.255.0 mininet> h3 ifconfig h3-eth0 192.168.23.3 netmask 255.255.255.0 mininet> h1 route add default gw 192.168.12.2 mininet> h3 route add default gw 192.168.23.2 mininet> h2 sysctl net.ipv4.ip_forward=1
h1看ping通h3了:
mininet> h1 ping -c 1 192.168.23.3
以上是用mininet搭建一個基礎的路由實驗的詳細內容。更多資訊請關注PHP中文網其他相關文章!
