# 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for its actual purpose, this should be done as far as possible without stirring up a lot of dust (e.g. using various outdated network backends).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
