A method for implementing Virtual Router Redundancy Protocol (VRRP) on a Resilient Packet Ring (RPR), including: setting an interface supporting a plurality of Medium Access Control (MAC) addresses for each RPR interface of network devices to constitute VRRP groups; classifying the RPR interfaces of network devices to constitute VRRP groups, and the interfaces supporting a plurality of MAC addresses, into one virtual local area network (VLAN); running the VRRP in the classified VLAN to generate at least one virtual layer 3 switch device. Also, the present invention discloses a system for implementing VRRP on an RPR. In the method and system of the present invention, a plurality of virtual layer 3 switch devices are generated by means of setting a VE interface in the network device and running the VRRP in the VLAN which contains both the VE interface and the RPR interface.
