问题
I am running a Python script on mininet (virtual machine), which looks like this:
def main():
setLogLevel('info')
net = Mininet(switch=LinuxBridge, controller=None)
h1 = net.addHost('h1', ip=None)
h2 = net.addHost('h2', ip=None)
s0 = net.addSwitch('s0')
s1 = net.addSwitch('s1')
s2 = net.addSwitch('s2')
r1 = net.addHost('r1', ip=None)
r1.cmd('sysctl -w net.ipv6.conf.all.forwarding=1')
r2 = net.addHost('r2', ip=None)
r2.cmd('sysctl -w net.ipv6.conf.all.forwarding=1')
net.addLink(h1, s1)
net.addLink(r1, s1)
net.addLink(r1, s0)
net.addLink(r2, s0)
net.addLink(r2, s2)
net.addLink(h2, s2)
h1.cmd("ip -6 addr add 2001:638:709:a::1/64 dev h1-eth0")
h2.cmd("ip -6 addr add 2001:638:709:b::1/64 dev h2-eth0")
r1.cmd("ip -6 addr add 2001:638:709:a::f/64 dev r1-eth0")
r1.cmd("ip -6 addr add 2001:638:709:f::1/64 dev r1-eth1")
r2.cmd("ip -6 addr add 2001:638:709:f::2/64 dev r2-eth0")
r2.cmd("ip -6 addr add 2001:638:709:b::f/64 dev r2-eth1")
h1.cmd("ip -6 route add 2001:638:709::/48 via 2001:638:709:a::f dev h1-eth0")
r1.cmd("ip -6 route add 2001:638:709:b::/64 via 2001:638:709:f::2 dev r1-eth1")
r2.cmd("ip -6 route add 2001:638:709:a::/64 via 2001:638:709:f::1 dev r2-eth0")
h2.cmd("ip -6 route add 2001:638:709::/48 via 2001:638:709:b::f dev h2-eth0")
net.start()
CLI(net)
net.stop()
After running it, when I do h1 ping6 2001:638:709:b::1
I get an error that
Address family not supported by protocol
if i try h1 ping6 2001:638:709:b::f/64
, I get unknown host
.
What is the correct method to verify the networks?
