IPv6 and TunnelBroker
The first step is the registration and setup of a tunnel to our IPv4 address. Second step the configuration of the tunnel on our side. The webiste includes many examples of tunnel configuration, in my case Cisco IOS:
configure terminal interface Tunnel6 description Hurricane Electric IPv6 Tunnel Broker no ip address ipv6 enable ipv6 address 2001:470:99:15::2/64 tunnel source 220.127.116.11 tunnel destination 18.104.22.168 tunnel mode ipv6ip ipv6 route ::/0 Tunnel6 end write
And this is the LAN interface of the router:
inte vlan 1 ipv6 address 2001:470:98:15::/64 eui-64 ipv6 nd ra interval 10
Notice that I reduced the router advertisement interval to speed up the configuration of the clients.
HE routes two prefixes through the tunnel, a /64 and a /48 so we can test one or more IPv6 subnets on the local site.
On my Win7 laptop I’ve just enabled IPv6 protocol on the interface (it was already enabled actually) and the ping is ok:
C:\>ping 2001:470:20::2 Esecuzione di Ping 2001:470:20::2 con 32 byte di dati: Risposta da 2001:470:20::2: durata=124ms Risposta da 2001:470:20::2: durata=151ms Risposta da 2001:470:20::2: durata=147ms Risposta da 2001:470:20::2: durata=110ms Statistiche Ping per 2001:470:20::2: Pacchetti: Trasmessi = 4, Ricevuti = 4, Persi = 0 (0% persi), Tempo approssimativo percorsi andata/ritorno in millisecondi: Minimo = 110ms, Massimo = 151ms, Medio = 133ms
We can verify online if IPv6 Internet access is working fine on websites like test-ipv6.com
So no more excuses, let’s start to practice IPv6 and be ready for it and join the World IPv6 Day.
You can either do a planned, careful migration, or you can do it in a panic, and you should know full well that panicking is more expensive.”
