Router Announcements Linux

SummaryRouter announcement are used by network devices to perform stateless address autoconfigurations (SLAAC).  Linux machines can be configured to send out these router announcements (RA) to its neighbors. Most linux distribution comes default with a RA daemon, however, some manual configuration is required.
Modifying /etc/radvd.conf Modify fields as needed (almost certainly including the interface name and prefix)

##include the code below to configure router announcements

#state the interface that will be announcing the RA

interface eth0                   


    # We are sending advertisements (route)

    AdvSendAdvert on;

    # Advertise no more than every 30 seconds
        MinRtrAdvInterval 30;

    # Advertise at least every 100 seconds
        MaxRtrAdvInterval 100;

    # Netmask length must be "/64"

     prefix 2001:DB8:1:0/64


         # Says to hosts:"Everything sharing this prefix is on the same link as you."

         AdvOnLink on;

         # Says to hosts: "Use the prefix to autoconfigure your address"

         AdvAutonomous on;

         AdvRouterAddr on;
