MX250 WAN1 and WAN2 uplink changes for unknow reason
My WAN1 and WAN2 uplink keep switching back and forth. For unknown reasons the uplink goes into failover mode and switches from the primary uplink to the secondary uplink. I have been on phone with my ISP monitoring our ONT and there are zero dropped connections. Of course, the amazing Event log that Meraki provides us shows zero detail concerning why the primary uplink status has changed. I know the MX performs failover connectivity tests to determine uplink status and it's possible it's failing one of these tests. But since there is no detail for this event in the so-called event log. How am I able to diagnose that one of these test failures is the possible root cause of the problem?
I have been on the 18.106 firmware for some time now, although I see 18.107 is available now. I'm working with my ISP and provided a packet capture just filtering the ARP. But now I'm thinking of including ICMP, ARP and DNS to get a better view.
