Hi All, looking for some assistance to configure VPN failover for DR/BCP.
I've attached a basic diagram below
Currently, static route monitoring is set up on the outside interfaces of the firewalls at Site A, so if upstream from Site A ISP 1 fails Site A will use Site A ISP 2 to start forwarding traffic out.
From Site A we have two VPN tunnels built to allow Site A LAN to Site B LAN, Site B is also allowed to Site A using the same tunnels.
If Site A ISP 1 fails and we swap across to Site A ISP 2, is there a method to bring up the Site A ISP 2 Tunnel 2 automatically without having an IP assigned to the interface?
Site A already has static routing to Site B via the second tunnel, with a higher metric.
Ideally, I would like Site A to monitor (from its own mgmt loopback IP) the mgmt loopback interface at Site B and fail across the tunnel if it isn't reachable
