We currently use OSPF to route our PtP /30 uplinks between our core and each tower site. Each tower site is equipped with a RB450G. We have several towers that we need to implement some type of redundancy on. We are thinking of deploying an additional pair of wireless backhauls (Canopy, UBNT, etc) between our main distribution tower and the remote tower. I would like to be able to automatically fail over to this second set of backhauls if the primary set goes down and so forth.
Can someone give me some pointers as to the best way to implement this type of redundancy?
