There is a LAN Health-check feature on the VPNC that you could use:
Enabling LAN health check will bring down WAN IPSec tunnels on the VPNC if all route peering is lost on the VPNC LAN - This is done to prevent black holing traffic.
Also, if the next-hop router fails and thus the peers route updates fail - the VPNC would stop advertising those routes into the SDWAN Overlay. Unless of course there is a broad DC Aggregate that matches an interface on the VPNC.

Hello,
I would like to know if there is a way to configure health check on VPNC like it can be performed on BGW :
Airheads CommunityThe goal is to check if next-hop router is UP or KO in order to remove the next-hop in the routing table.
Best regards,
