Bonjour,

on en a déjà parlé quelque part sur le forum mais je ne sais plus où.

Ma livebox ne m'attribue plus d'ipv6 (elle est allumé depuis 15 jours et 12h, j'avais une ipv6 hier soir, je n'en ai plus cet aprem.)
Elle a bien une ipv6 mais n'en attribue plus ni à mon PC (Windows 8.1), ni à mon téléphone sous Android .. et l'état du DHCPv6 est vide (cf PJ ci-dessous).


Un reboot fonctionnera surement, je tenterai çà demain.

Je pense aussi.

J'ai posté au cas où quelqu'un d'Orange voudrait que je vérifie 1 ou 2 choses.

Ca n'est pas le DHCPv6 qui attribue les IPv6 mais l'autoconf par annonce du routeur (RA). Le DHCPv6 de la livebox est 'stateless' et sert a fournir la config DNS aux postes qui ne supportent pas l'option RDDNS (config DNS via RA), notamment les postes sous Windows.

Dans le cas présent, c'était plutôt le service RA de la livebox qui était planté. On a constaté que cela arrivait parfois, dans certains cas il faut meme faire un reset complet de la livebox, un reboot n'étant pas suffisant.

la ligne "état DHCPv6" est toujours vide meme quand tout marche.

A mon avis c'est quasi le meme code dedans. Y'aura peut-être un upgrade du firmware de la LB3 quand la LB4 sortira.

Tu crois que c'est matériel ? J'en doute vu les composants qu'il y a dedans.

Le code est complexe parce qu'il utilise le SDN d'Orange via ODL Nemo (https://www.opendaylight.org/)
La configuration de chaque fonction est décrite dans un langage de description (.odl) qui est "exécuté" dans la livebox par un binaire spécifique qui pilote la conf Linux en dessous.

par exemple, voila ce qui configure radvd :
using "ra.so";

acl {
    group cwmpd read,write,execute;

persistent object RouterAdvertisement {

Bref je ne serais pas étonné que ces composants 'SDN' soit buggés.

Ca peut être aussi tout bêtement leur version de radvd qui n'a pas été mise a jour...

Tout le FLOSS d'Orange est maintenant centralisé ici: http://opensource.orange.com/

Si t'es sous Linux tu peux utilisé "radvdump" pour voir si les RA sont toujours actifs (lancer la commande et attendre un peu).

Sous Windows ou Mac, on peut voir ca avec une capture réseau éventuellement (j'ai fait un post la dessus quelque part sur le forum mais je le ne retrouve plus).
