View source for Configuration IPv6

Une fois le RPi3 booté avec ses modules chargés la commande ifconfig -a rend cela :

 <nowiki>
root@raspberrypi:~# ifconfig -a

On voit que le wpan0 n'est pas UP et qu'il n'existe pas d'interface lowpan0

Il faut créer le lien entre ce qui est un port de bridge wpan0 et ce qui deviendra une interface lowpan0 puis mettre ces interfaces UP.

 <nowiki>
ip link add link wpan0 name lowpan0 type lowpan
ifconfig wpan0 up
ifconfig lowpan0 up

</nowiki>
On a alors la configuration suivante :

Les circuits at86rf230 sont faits de telle sorte que la mac adresse du composant change à chaque reboot du coup, il vaut mieux fixer une adresse IPv6 à cette interface pour savoir à qui l'on parle ;-)
Par exemple sur une carte qui sera le routeur :
 <nowiki> ip addr add fd28::1/64 dev lowpan0 </nowiki>
Et sur l'autre... 

 <nowiki> ip addr add fd28::2/64 dev lowpan0 </nowiki>

Pour obtenir enfin ce que nous voulions :

 <nowiki>
root@raspberrypi:~# ping6 -I lowpan0 fd28::2
