Meraki MS - Warm spare VRRP
Hello Experts,
I have configured the warm spare between Meraki MS switches and it's working fine but I could not find the VMAC anywhere in the switch, I know it starts with 88-15-44 but wanted to know the full virtual MAC of the switch.
I can find it by taking packet captures but want to know how Switch calculates it.
Any RFC to refer for it?
Regards,
Pavan

The VRRP MAC address will not be available on the dashboard. But can be easily identified as the first 3 octets are always "cc:03:d9" and the last two octets are always of the primary MX as it sends the virtual mac as a part of the VRRP process.

As per the document, the first three octets would be 88:15:44, I want to know the calculation for the last three octets

Take a packet capture , it should be the lact 3 octets of the switch that is currently the primary.

I took the captures
Primart MAC - 14:9f:43:a3:ad:e8",
Secondary mac- 14:9f:43:a4:09:88",
VMAC": "88:15:44:38:00:01"
so the calculation you mentioned does not match
