Hi everyone,
I am working with ovs 2.3.0, mininet 2.1.0, all set-up at ubuntu 14.04. I
created mininet topology as given below:
s1 = self.addSwitch('s1')
s2 = self.addSwitch('s2')
s3 = self.addSwitch('s3')
h1 = self.addHost('h1')
h2 = self.addHost('h2')
h3 = self.addHost('h3')
h4 = self.addHost('h4')
self.addLink(h1, s1)
self.addLink(h2, s1)
self.addLink(h3, s2)
self.addLink(h4, s2)
self.addLink(s1, s3)
self.addLink(s2, s3)
and configured two vxlan tunnels on s1 and and s2 with the following
commands:
ovs-vsctl add-port s1 tun0 -- set interface tun0 type=vxlan
options:remote_ip=193.168.10.11 options:key=111
options:local_ip=193.168.10.10
ovs-vsctl add-port s2 tun1 -- set interface tun1 type=vxlan
options:remote_ip=193.168.10.10 options:key=111
options:local_ip=193.168.10.11
ovs-vsctl add-port s1 tun2 -- set interface tun2 type=vxlan
options:remote_ip=172.168.10.11 options:key=222
options:local_ip=172.168.10.10
ovs-vsctl add-port s2 tun3 -- set interface tun3 type=vxlan
options:remote_ip=172.168.10.10 options:key=222
options:local_ip=172.168.10.11
But when I ping h4 from h1, they do ping each other. According to my
knowledge of multi-tenant data centers and network virtualization, hosts
configured at different tunnels should not ping each other.
Does ovs ensure isolation? If yes, then how? OR Do I need to ensure this
isolation in controller manually?
Please clear me at this point. Any help/suggestion would be highly
appreciated.
Thanks and Regards,
