VRRP Active-Active

VRRP Active-Active mode allows you to have two active VRRP masters in conjunction with MLAG (Multi-switch Link Aggregation Group) by applying an ACL (Access Control List) on the ISC 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 link.

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

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