Configuring the IPv6 setup and 6rd Tunnel function of the Linksys Wi-Fi Router, E900

The Internet Protocol version 6 (IPv6) is the new generation protocol to succeed the current protocol version, Internet Protocol version 4 (IPv4).  IPv6 was created to address the concern about the shortage of IPv4 addresses available.  It also adds many improvements to IPv4 in areas such as routing and network auto-configuration.  This article will guide you on how to configure the IPv6 and 6rd Tunnel function on your Linksys Wi-Fi Router, E900.
To configure the IPv6 setup and 6rd Tunnel function of your Linksys Wi-Fi Router, E900, make sure that you have the following information from your Internet Service Provider (ISP): 

  • Network Setup Prefix
  • Prefix Length
