I have a QUAD WAN Draytek 3900 Router and want to set it up for high availability.
The 3900 has some nice high availability features whereby if you configure a master and a backup 3900 and the master router fails, the backup router will become active and takeover.
My concern is that the four WAN inputs would still be in ROUTER1 - which has now failed - so I would need to unplug and plug in those 4 WAN cables into ROUTER2 in this case.
So this isn't actually high availability.
Can somebody advise?
