I opted to conduct failover testing by implementing double WAN redundancy. Instead of utilizing trunk ports, I tried using access ports for VLAN 10,20 with a trunk on the Link Aggregation Group (LAG) between the switches.   Equipment:   2x MS390 2x MX68   TEST1: The failover process worked seamlessly when I removed the WAN 1 cable from the primary firewall, successfully transitioning to WAN 2 on MX1.   TEST2: Upon removing the cable from VLAN 10, the expected behavior was for the MX to failover to its spare unit. However, this did not occur, despite the fact that VRRP messages were supposed to be continuously exchanged between the MX devices.   Has anyone else ever tested this, and if so, were they able to observe similar results or encountered different outcomes?     Thanks! ...
