Abstract: The embodiments of the present invention disclose a method, apparatus and system for implementing routing aggregation, which relate to communication field, and solve the problem that too many routings advertised on the DHCPv6 relay agent leads to huge number of routing table entries of the backbone network. The technical solution of the present invention comprises: sending a message to a dynamic host configuration protocol DHCPv6 relay agent, such that the DHCPv6 relay agent generates an aggregation routing of requesting router prefix routings according to the message; wherein the message comprises information about a prefix pool which assigns address prefixes to the requesting routers access to the DHCPv6 relay agent or aggregation routing destination address information generated according to the information about the prefix pool. The method, apparatus and system for implementing routing aggregation may be applied in DHCPv6 network constructions.
