3.10. Configuring the radvd service for IPv6 routers

Procedure

1. Install the radvd package:

   # dnf install radvd

2. Edit the /etc/radvd.conf file, and add the following configuration:

   interface enp1s0
   {
     AdvSendAdvert on;
     AdvManagedFlag on;
     AdvOtherConfigFlag on;
   
     prefix 2001:db8:0:1::/64 {
     };
   };

   These settings configure radvd to send router advertisement messages on the enp1s0 device for the 2001:db8:0:1::/64 subnet. The AdvManagedFlag on setting defines that the client should receive the IP address from a DHCP server, and the AdvOtherConfigFlag parameter set to on defines that clients should receive non-address information from the DHCP server as well.

   For further details, see the radvd.conf(5) man page on your system and the /usr/share/doc/radvd/radvd.conf.example file.

3. Optional: Configure that radvd automatically starts when the system boots:

   # systemctl enable radvd

4. Start the radvd service:

   # systemctl start radvd
