如何在Mininet中修改host的IP地址

how to update virtual host's IP in mininet？

I got it! do like this:

mininet> py h1.setIP('10.0.0.3/24')
mininet> py h2.setIP('10.0.0.4/24')
mininet> h1 ping h2
PING 10.0.0.4(10.0.0.4)56(84) bytes of data.
64 bytes from10.0.0.4: icmp_req=1 ttl=64 time=2.38 ms

Hi everyone,

 

When I change host's IP, other hosts cannot ping through it, but it can ping other host.

And I find that, when typing in dump command, it shows that the IP is not changed.

That's why? How can I really change the ip of virtual host?
