We are going to add an ethernet point to point Wifi link between our HO-Branch office.right now we have a serial leased line 512kB link between these two location. we are running OSPF as routing protocol.now my concern is regarding the cost value since fastethernet link has cost 1 the ethernet link will prefer to route the traffic.( we actually plan to keep primary as Wifi-ethernet link)
Since ethernet interface never go down(always show up) when the connectivity loses to the other end will the traffic switch over to serial leased line?
If no any method to make it switch over.
Thanks in advance
