Abstract: A method for network device redundancy backup includes performing communication and exchanging a VRRP message directly between VRRP master and backup routers to negotiate a master and backup relationship and sending, by the VRRP master device using an interface connected to an access device, a gratuitous ARP packet to the access device, so as to instruct the access device to direct user traffic to the VRRP master router. According to this method, the VRRP master and backup routers communicate and exchange a VRRP message directly, and the VRRP master router sends a gratuitous ARP packet to an access device through an interface connected to the access device.
