Third backup VPN, 2 over cable connection third over LTE?
I have two VPNs over cable, one to our main site and a backup to our DR site. I am using the monitor command, it works great.
Would there be a way to have a third VPN that would come up if the first two failed going out another interface and then over LTE via a Cradlepoint? I would prefer to not have to build a VPN from the Cradlepoint.
You can rely on ike dpd (dead peer detection feautre) feature to kick in the vpn failover to third link. make sure 3rd vpn static route is configured with higher AD than first 2 vpn routes. in this case if the first 2 vpns are down, 3rd will kick in auto(if auto-negotatite is enable on phase2) or traffic will trigger the tunnel negotation.
