Coucou,
J'avais remarqué il y a quelques semaines des intermittences pour mon
papa qui a sa boite mail sur une VM TTN et qui est connecté au réseau
CHD. On a regardé avec Laurent puis ça avait disparu le temps de
comprendre. Ça semble recommencer ou persister.
Ce que j'ai pu voir pendant que ça pas marche™ à 19h16 depuis h7 (la PJ
est un show bgpmap pour l'IPv6 du PC fixe de mon père, le chemin préféré
semble via Touix_RS1) :
TL;DR: ni 2a03:a0a0:0:8001:8e89:a5ff:fe67:2dcc (mon papa) ni
2001:978:2:68::8:2 (nexthop de h7 pour cette destination) ne répondent
au ping6. Il y a 9 routes v6 sur h7 en ce moment avec ce nexthop.
Je ne touche à rien.
