MX warm spare without LAN virtual IP ?

Hi,

I'm confused about configuring my meraki MX cluster :

 

In this documenation :

 https://documentation.meraki.com/MX-Z/Other_Topics/Warm_Spare

 

I found : 

"LAN IP addresses are configured based on the Appliance IPs in any configured VLANs. No virtual IPs are required on the LAN."

 

How can I configure HA without LAN virtual IP ? What will be the gateway for my switch ?

 

Can anyone help please ?

It isn't written very well.  The MX's use VRRP, which in essence is a virtual IP.  The IP address is always serviced by the primary MX.  The spare takes over the VRRP IP address if the primary fails.

only 1 mx is active for all your vlans. you can't config the different vlans on the 2nd mx when they are in warm spare.

Thank you PhilipDAth, is it the same for WAN interfaces ?

Re: MX warm spare without LAN virtual IP ?

The WAN interfaces each need their own IP address, and if there is a common subnet, you can also enable a Virtual IP.  Using a virtual IP on the WAN interfaces is an optional configuration.
