Link Backup with OC-200 and ER605 Gateway not working as expected
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Hello!
Since I have 2 Internet Providers in my home, I want to configure "Link Backup" on my OC200/ER-605 setup.
I made the following settings on OC200.
Settings --> Wired Networks --> Internet
WAN = My main ISP
WAN/LAN1 = My secondary ISP
Online Detection Intervall: 1 Minute
Application optimized routing: Enable
Link Backup: Enable
Backup WAN: WAN/LAN1
Primary WAN: WAN
Backup Mode: Always Link Primary
Mode: Enable Backup Link when any primary WAN fails
I have now noticed the following behavior.
If I remove the cable from Primary WAN, the Backup WAN kicks in.
I am now assuming that in the event of a power outage or hardware damage the LINK BACKUP will work just fine.
However, the Backup WAN will not kick in if the Primary WAN has no data throughput (e.g. in case of an internet failure, like missing sync to ISP)
Why does "Link Backup" not work in the event of an internet failure?
It would be nonsense if ony the connection to my ISPs modem is checked, and everything that comes after is not of interest.
Can you explain to me, how the Online Detection on OC200/ER605 is working?
I hope someone can help.
Yours sincerely,
Patrick
