If virtual routers exist and are monitoring a WAN interface, but none of them is in the "Master" state, the VRRP requests a disconnect of the monitored WAN and prevents a reconnect. As soon as one of the routers changes to the Master state, the connection can be re-established and a connection attempt is started. Since WAN connections for IPv4 and IPv6 are established and terminated together, the IP version of the virtual routers is irrelevant. In general: If the VRRP control VRRP activate is not enabled, the VRRP has no influence on the WAN backup module.
Important: Also note the switch (2.141.7).
