Routing table updating method, EVPN control equipment and EVPN system

A routing table updating method, EVPN control equipment and an EVPN system are relates to the communication field. Resource cost of PE equipment during routing table updating can be reduced. A specific scheme is characterized in that control equipment acquires a PE equipment parameter of an EVPN, wherein the PE equipment parameter is used for indicating a connection relation between the at least two pieces of PE equipment; the control equipment acquires a local network terminal identification of each piece of PE equipment in the at least two pieces of PE equipment; and the control equipment determines a topology of the EVPN according to the PE equipment parameter and determines an EVPN routing table of each piece of PE equipment in the at least two pieces of PE equipment according to the topology of the EVPN and the local network terminal identification of each piece of PE equipment in the at least two pieces of PE equipment, and the control equipment sends the EVPN routing table of each piece of PE equipment in the at least two pieces of PE equipment to the corresponding PE equipment.
