FS#4527 — BFD

Attached to Project— Reseau Internet et Baies
Amélioration
Tout le réseau
CLOSED
100%
Nous avons testé le BFD sur l'OSPF (Bidirectional Forwarding Detection)
entre ldn-1-6k et ams-1-6k. Cela fonctionne bien. Par contre au moindre
surcharge du routeur, le BFD ne repond pas bien et le lien est declaré
down. C'est une fonctionnalité trop dangereusse pour la mettre en production.
Nous allons nous en passer. C'est à dire que quand le lien est down, l'OSPF
mettra entre 1 à 3 secondes pour rerouter les packets au lieu de entre
50 et 250ms.

test fait avec

ip ospf bfd
bfd interval 50 min_rx 50 multiplier 5

ça a sauté de suite

ip ospf bfd
bfd interval 250 min_rx 250 multiplier 3

ça a tenu la nuit puis à nouveau plusieurs faux positives
