Abstract
A first network device may activate the first network device as being associated with a Virtual Router Redundancy Protocol (VRRP) group. The first network device may receive, from a second network device, a duplicate address detection message. The first network device may compare a data link layer address associated with the duplicate address detection message and a Virtual Media Access Control (VMAC) address of the VRRP group. The first network device may disregard the duplicate address detection message after comparing the data link layer address and the VMAC address of the VRRP group.
