sudo python test2.py利用mininet构建下面的拓扑，并测试能否ping通：
路由器会自动生成本路由器激活端口所在网段的路由条目，即直接路由，因此要让两主机之间能ping通，只要造A, B中分别添加静态路由即可 (当然还要在两主机之间添加默认路由)。 上述拓扑的代码如下 (构建四个主机h0, h1, h2, h3, 最后其中h1, h2作为路由器) ：
#!/usr/bin/python

class HostTopo(Topo):
def create_nodes(self, length):
for i in range(0, length):
self.host_list.append(self.addHost('h' + str(i)))
def create_links(self, length):
for i in range(0, length-1):
self.addLink(self.host_list[i], self.host_list[i+1])
def __init__(self, length):
logger.debug("Class SimpleTopo init")
self.host_list = []
Topo.__init__(self)
self.create_nodes(length)
self.create_links(length)
def create_topo(length):
topo = HostTopo(length)
net = Mininet(topo = topo, link = TCLink, controller = None)
net.start()
CLI(net)
net.stop()
if __name__ == '__main__':
logger = logging.getLogger(__name__)
setLogLevel('info')
if os.getuid() != 0:
logger.debug("You are NOT root")
elif os.getuid() == 0:
create_topo(4)
先给每个接口配置相应的IP地址：
h1 ifconfig h1-eth0 192.168.1.1 netmask 255.255.255.0 h2 ifconfig h2-eth0 192.168.1.2 netmask 255.255.255.0 h3 ifconfig h3-eth0 192.168.2.1 netmask 255.255.255.0 h4 ifconfig h4-eth0 192.168.2.2 netmask 255.255.255.0
添加路由：
dev interface, interface是指本路由器 (不是相连的另一个路由器) 转发分组所用的接口，gw Getway, Getway是指相连的另一个路由器的接口IP地址。
接下来给h1, h2启动ipv4转发功能：
测试h0 -> h3, h3 -> h0：
测试成功。
小结 1 . 直接路由在给接口分配IP地址的时候就自动生成直连路由了，静态路由需要手动配置。 2 . 添加路由的时候，interface, Getway 指代的对象要清楚。
