IPv6-Lab

Initial situation

In this project, a laboratory for IPv6 will be set up using a desktop computer with a current Debian system. To use the computer furthermore for its actual purpose, this should be done as far as possible without stirring up a lot of dust (e.g. using various outdated network backends).

OS: Debian GNU/Linux 12
Kernel: 6.1.0-18-amd64
Network backend: NetworkManager
Hypervisor: KVM
Virtual switch: Open vSwitch 3.1.0

Required packages

openvswitch-switch
gvncviewer

Network topology

Configuring the bridge

Info about current connetions

# nmcli con show

Add bridge

# nmcli con add type bridge ifname labBridge0

Add interface to the bridge

# nmcli con add type bridge-slave ifname wlp4s0 master labBridge0

Turn on the bridge

# nmcli con up bridge-labBridge0

Create virtual network on hypervisor

Here we create a new network to be used by the edge router torino by creating a new file named bridged-network.xml with the following content

<network>
    <name>bridged-network</name>
    <forward mode="bridge" />
    <bridge name="br0" />
</network>

To create the network on the hypervisor, run

$ virsh net-define bridged-network.xml

Then start it

$ virsh net-start bridged-network 
$ virsh net-autostart bridged-network 
$ virsh net-list
 Name              Status   Automatischer Start   Bleibend
