How to Configure IPSec VPN Failover

This example shows how to use the VPN Setup Wizard to create a site-to-site VPN
with failover. The example instructs how to configure the VPN tunnel between
each site if one site has multi-WAN. When the multi-WAN VPN failover is
configured, IPSec VPN tunnels automatically fail over to a backup WAN
interface if the primary WAN interface becomes unavailable.
