VRRP Active-Active

VRRP Active-Active mode allows you to have two active VRRP masters in conjunction with MLAG by applying an ACL on the IST links in order to block VRRP updates.

When you configure VRRP with MLAG, you have the option to make VRRP operate in active-active mode. For MLAG peers to operate in VRRP active-active mode, configure the following ACL on both ends of the ISC port.

entry vrrp-act {    
if match all {    
    destination-address 224.0.0.18/32 ;   
} then {    
    deny ;   
       }    
}  

There are two caveats that you need to be aware of that are illustrated in the following figure:
