I was wondering how I could introduce failover to my network. We have six backhauls from our central tower.
Here is an example of what I would like to make happen:

Our network is entirely bridged with VLAN’s. I obvoiusly don’t want to cause network loops. I would like to leave the failoverlinks running. If I can’t, one thing I was thinking about is having some sort of a watchdog service running on the failover links and if the Primary Backhaul is detected down then the watchdog enabling the wireless link for the failover.
Any help or suggestions are appreciated.
