Hi there, I have two sites connected via MPLS network. In each site, ASA is connected to the MPLS router. Each ASA also connected to an ISP via another router. I would like to configure a VPN tunnel between the two sites that will be only used if MPLS connection is not available. I know how to configure the tunnel and actually created one but don't know how to designate it as a backup and how to monitor the MPLS connection. Please help.
