I have a WAN link that occasionally fails into a mode where, essentially, every other packet will make it through.
This means the link is up just enough to be “up” but not up enough for my purposes. I would like the router to disable this interface when in this situation.
Is there a sure-fire way to configure for this? Ideally I would like multiple ICMP echos and to set a threshold percentage for success, or something similar. I’m open to other ideas, though!
