Duplicate IP address detected for VIP - CSS

[jeanSamarani_2]

Hi Guys

We have two CSS one Master and the other is in backup mode.

We are getting the below message regarding the same duplicated IP address on both CSS but each one with different mac address. 

However, the OUI "00-1f-9e" shows that this for a Cisco Device.

Could be the issue from the load balancers themselves? Can anyone advise what could be the problem?

CSS1:

JUL 20 20:34:58 1/1  677 IPV4-4: Duplicate IP address detected for vip: 10.160.x.y 00-1f-9e-20-44-a0

CSS2:

JUL 19 10:12:47 1/1 753 IPV4-4: Duplicate IP address detected for vip: 10.160.x.y 00-1f-9e-20-41-9d

Appreciate your help!

Can you identify those MAC addresses, on what devices are assigned?

A config snippet would help of both the CSS. Are you sure the set up the circuit vlans and redundant interfaces correctly with the right vrrp address?
