Bonjour à tous,
J'ai remplacé depuis plusieurs années, bien avantageusement le modem Zyxel OVH par un erl-3 (maintenant en firmware 2.0.9) pour la partie IPV4 (connexion OVH FTTH Profile A pppoe sans Vlan, collecte Kosc).
Ayant enfin fait l'effort de mieux comprendre IPV6, je pensais mettre en pratique sur une connexion de configuration simple avant de m'attaquer à un autre connexion Orange en ipv4 seule sur un ER4 (possibilité d'utiliser dhclient6.service en place de dibbler).
Je n'arrive malheureusement pas à obtenir d'IPv6, l'obtention de l'IPv4 /32 reste fonctionnelle.
J'ai suivi les recommandations de Kgersen
https://lafibre.info/ovh-fai/ovh-fibre-pro-et-ipv6-comment-la-faire-fonctionner-sur-routeur-mikrotik/msg1086270/#msg1086270 , et ma configuration est assez conforme à ce que l'on trouve sur le forum et ailleurs pour l'auto-configuration IPv6 en pppoe.
j'ai essayé quelques variantes de configuration de dhcpv6-pd (prefix-only, dhcpv6-stateless, slaac), de pppoe (rapid-commit disable, multilink...), de firewall mss-clamp-6 à 1432, sans succès.
La commande $ show interfaces ne m'affiche pas l'IPv6 /56 attribuée par OVH.
Est-ce toujours un défaut de conformité RFC4638 permettant PMTUD, comme le rapportait LROB il y a 2 ans
https://lafibre.info/ovh-fai/besoin-daide-ovh-ftth-mikrotik-ipv6/msg1062640/#msg1062640 ? Je n'arrive pas à transcrire sur EdgeRouter le contournement qu'il propose pour Mikrotik!
Pouvez-vous m'apporter votre expertise?
Ci-dessous ma configuration complète:
