Example 1

In this example two network namespaces are connected together by a simple bridge instance.

The following code configures the network namespaces and virtual network interfaces to be used.

# copy and paste in your terminal

# namespace ns1 -> veth1 10.0.0.1/24
# namespace ns2 -> veth2 10.0.0.2/24

for i in `seq 1 2`;
do
    sudo ip netns del ns${i} > /dev/null 2>&1 # remove ns if already existed
    sudo ip link del veth${i} > /dev/null 2>&1

    sudo ip netns add ns${i}
    sudo ip link add veth${i}_ type veth peer name veth${i}
    sudo ip link set veth${i}_ netns ns${i}
    sudo ip netns exec ns${i} ip link set dev veth${i}_ up
    sudo ip link set dev veth${i} up
    sudo ip netns exec ns${i} ifconfig veth${i}_ 10.0.0.${i}/24
done

Create a simple bridge instance, add and connects ports to virtual interfaces

# create instance
polycubectl simplebridge add br0

# add and connect port to veth1
polycubectl br0 ports add toveth1 peer=veth1

# add and connect port to veth2
polycubectl br0 ports add toveth2 peer=veth2

Ping between namespaces

# ping ns1 from ns2
sudo ip netns exec ns2 ping 10.0.0.1

Print whole br0 status

polycubectl br0 show

Delete ports

polycubectl br0 ports del toveth1
polycubectl br0 ports del toveth2

Remove br0

polyubectl del br0
