Just need some info. We would like to use ADSL as a backup link for one of our remote sites. Its main connection back to the HQ is a fibre connection but if this goes down I would like to use the ADSL connection to kick in as a backup. I am going to set this up as a Lan to Lan connection back to our HQ. Is there anyway I can have this kick in automatically when the fibre goes down? If so I am not sure how to accomplish this can I use IP SLA? Would appreciate some info.
