I am trying to do a failover encase our primary feed (A) is down. to our secondary feed (B). I am having lightning problems striking the tower and killing the equipment at (A) I have tried to do the failover shown in the wiki http://wiki.mikrotik.com/wiki/OSPF_to_simulate_full_duplex_links_with_redundancy but for some reason (me) I cant seem to get it to work. It passes traffic for a while 30 to 48 hours then the link drops but doesnt switch over to the secondary link.
