ABSTRACT:
A method for managing Virtual Router Redundancy Protocol (VRRP) backup groups includes: setting a VRRP Group Management Protocol (VGMP) group including at least one VRRP management group. Each VRRP management group includes at least one VRRP member, and the VRRP members belonging to one VRRP management group belong to different VRRP backup groups respectively; the VGMP group manages the included VRRP management groups uniformly. Embodiments of the invention manage multiple VRRP backup groups in devices based on the new VGMP protocol, and can guarantee the state consistency of multiple VRRP backup groups so as to realize reliable transmission of services requiring the consistency of to-and-fro paths. Meanwhile, embodiments of the invention can decrease the switching delay of the VRRP so as to meet the demands of telecommunication level carrier network when the VRRP is employed to perform route backup.
