View source for How to setup a 6to4 tunnel using anycast (RFC 3056)

== Introduction ==

This page details the process for setting up a tunnel for IPv6 using the transition mechanism detailed in [http://www.ietf.org/rfc/rfc3056.txt] using the <b>anycast</b> address 192.88.99.1

== Instructions ==
All commands listed are run as a user with sufficient privileges.  To obtain root privileges, enter {{command|su -}} and supply the ''root'' user password.
<pre>
ip tunnel add tun6to4 mode sit ttl 80 remote any local DIR_PUBLIC_IPv4
ip link set dev tun6to4 up
ip -6 addr add 2002:XXYY:ZZUU::1/16 dev tun6to4
ip -6 route add default via ::192.88.99.1 dev tun6to4 metric 1
</pre>
Note that XXYY:ZZUU is the hexadecimal notation for DIR_PUBLIC_IPv4 (the public IPv4 address) as follows:
60.172.21.22 -> XXYY:ZZUU = 3CAC:15DE
