The invention discloses a method and a device for realizing a user access multi-homing network and network equipment, and solves the problem of dynamic routing loops generated when a user access network uses CE multi-homing networking. The method disclosed by the invention comprises that: a home location PE receives VPN routing information from other PE; if judging that the VPN routing information received from the other PE is required to be sent to homing CE, the home location PE reflects the VPN routing information to the other PE on the home location; and when receiving the VPN routing information from the homing CE, the home location PE judges whether the VPN routing information received from the homing CE is the same as the reflected VPN routing information, and if so, VPN routing entries are prohibited from being updated by the VPN routing information received from the homing CE. Because the home location PE filters routing which is received from the CE and possibly causes loops by utilizing the reflected VPN routing information, and the VPN routing information is not used to update the VPN routing entries, so the problem of the dynamic routing loops is solved.
