Installation of radvd daemon and configuration

Installing radvd

Open a Linux console and use the package manager of your choice to install radvd

sudo apt install radvd

Configuring radvd

radvd does not come with a default configuration file, instead we need to create one

• Create a new file under /etc/radvd.conf using the text editor of your choice (nano, vim…)

  sudo nano /etc/radvd/radvd.conf
  

  We're going to set it so radvd advertises a new prefix on eth0:

  interface eth0
  {
    AdvSendAdvert on; 
    MaxRtrAdvInterval 30; 
    AdvManagedFlag on; 
    AdvOtherConfigFlag on;
  
    prefix fd50:43e1:cede:4587::/64
    {
                  AdvOnLink on;
                  AdvAutonomous on;
    };
  
  };
  

  As you can see, these settings apply only for eth0 If you would like to get further information about the other settings that are used : radvd.conf

• Enable and start the the deamon

  sudo systemctl enable radvd.service
  sudo systemctl start radvd.service
  

At this point, every single machine that has an IPv6 stack, bridged to eth0 will generate one based on the prefix we set However we haven't enable routing yet,
