Bonjour,
Depuis environ une semaine je constate chez moi des pertes récurrentes de connexion internet.
Mon installation n'a pas bougé depuis quasiment 1 an.
Rapidement : j'ai 2 connexions internet, 1 fibre FTTH Red SFR et 1 xDSL Orange.
Ces 2 connexions sont load-balancées par un ERLite.
La connexion FTTH est utilisée en active et la xDSL en failover.
L'ERLite teste via un ping la route de chaque connexion, et lors de la défaillance de l'active (SFR) bascule sur la connexion failover. (Orange)
Pour faire simple j'ai fait un schéma de niveau CP
(cf pièce jointe)
En regardant je me suis aperçu que l'erlite détectait une perte de connexion sur ma FTTH et donc basculait automatiquement sur la connexion Orange.
Sauf que bien sûr je perds toutes les connexions actives en route et donc c'est la loose.
Au delà de ça c'est surtout la perte de connexion FTTH qui m'inquiète, j'ai regardé lorsque ça se produit (souvent) l'ONT est toujours vert fixe il n'a pas l'air désynchro.
Le "network unreachable" ne dure qu'environ 30s a 1mn et ca revient tout seul.
Du coup je ne sais pas trop par quel bout prendre le problème.
J'ai essayé de modifier la route-test de l'erlite mais ça ne change bien sûr rien (passage ping.ubnt.com vers 8.8.8.8 )
J'avais redémarré mon erlite hier matin, et rien qu'en 24h j'en suis déjà à 25 routes drop ! (27 le temps d'écrire ce message ...)
Voici les logs de l'erl :

J'ai demandé à Vivien si je pouvais avoir un smoke ping pour voir ce que ça donnait depuis l'exterieur, j'attend sa réponse.
Voila si quelqu'un à une idée d'investigation, je prend.
Merci d'avance.
