Hi @karthikeyanB ,


You can configure 2 VPN tunnels with each of remote side ISP connecting IP as remote peer. Configure tunnel monitor on primary one then configure two routes to remote LAN through each of the VPN tunnel with lower metric on primary.

Configure proper security policy for both the connections.


So if primary VPN is down, as the tunnel monitor is configured, the route to remote LANwill be removed and new route with higher metric will be in action which will make the secondary tunnel UP.
