Meraki MX HA (Warm Spare) Internet Failover Delay

[AMackie]

We're testing internet circuit failover on a pair of MX84s in HA (warm spare). When triggering a failure on the primary circuit we're seeing packet loss for up to 2-3 mins before connectivity is established on the secondary circuit. This seems a lot considering the auto-vpn requirements from multiple branch sites to the head-end. Is this normal behaviour for the Meraki MX84/100 appliances? If so, can the connectivity test period be reduced?

Can be up to 5 minutes depending on your design and how you simulate  the failure.  When you just unplug the wan1 it should be fast.

@AMackie if you use load balancing for auto VPN the traffic should failover pretty much instantly.  We have circuits go down for planned maintenance regularly and the users at the site don't get Citrix or VDI sessions disconnected and there is no interruption to surveillance live viewing
