Example 1 - Connectivity

In this example two network namespaces will be connected together by a 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 bridge instance, add and connects ports to virtual interfaces

# create instance
polycubectl bridge add br1

# add and connect port to veth1
polycubectl br1 ports add toveth1 peer=veth1

# add and connect port to veth2
polycubectl br1 ports add toveth2 peer=veth2

Ping between namespaces

# ping ns2 from ns1
sudo ip netns exec ns1 ping 10.0.0.2

Print whole br1 status

polycubectl br1 show

Delete ports

polycubectl br1 ports del toveth1
polycubectl br1 ports del toveth2

Remove br1

polyubectl del br1
