Meraki MX84 VPN Hub - Switchover to Warm Spare - Lossless?

[julian.bendix]

Hey Folks,

gonna have to press the beatuiful "Swap primary and spare device" on a productive MX84 which is acting as VPN Hub.

Anybody knows how this exactly behaves and if it is going to be lossless?

Thx and BR
Jules

Update here:

Had to do the switchover just earlier.

There was an outage for all services connected via Meraki VPN for almost 3 minutes.
It looks like the spare device starts sending VRRP Messages with highest priority after pressing the Swap button,
but then it took about 3 minutes until all IPSec Tunnels were up and functional on the new Primary.
