The VRRP module is closely linked to the WAN backup module to enable interaction between the two functionalities. The interaction is in both directions: On the one hand, VRRP can request or prevent the establishment of WAN connections depending on the state of the virtual routers, and on the other hand, the connection state of a WAN connection (established/backup/disconnected) can influence the priority used by the virtual routers.
A virtual router in the VRRP interacts with a maximum of one WAN connection (and its backup connections), and only if the name of the WAN connection is entered in the column Monitored interface in the configuration table Virtual routers. If there is no entry for a virtual router, this router does not interact with the WAN backup module.
