Draytek Router High Availability

Hello,

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?

Thanks

Basically your WAN needs to support it by giving multiple handoffs. In our cases of MPLS, we have redundant lines that service each HA router. Here's a link to some of the common wiring configs.
