Hello All,
I have a link that is flapping too fast for the 4G LTE (back-up) connection to take affect. When this happens there’s no way to access the router remotely. Is there any way to configure the fail over to happen faster ? Are there timers that can be increased/decreased or would an EEM script be a possible solution. I’ve included the 4G LTE config below.
Thanks
