Method, apparatus and system for implementing routing aggregation

A method for implementing routing aggregation, comprising:

• receiving, by a Dynamic Host Configuration Protocol version 6 (DHCPv6) replay agent, a message, wherein the DHCPv6 relay agent comprises one of a plurality of DHCPv6 relay agents, the prefix pool comprises a plurality of address prefixes and is divided into a plurality of parts which are assigned to the plurality of DHCPv6 relay agents, the prefix pool is shared by a plurality of requesting routers under the plurality of DHCPv6 relay agents;
• and
• generating an aggregated routing of requesting router prefix routings according to aggregated routing destination address information in the message, wherein the aggregated routing destination address information comprises information about an aggregated prefix of address prefixes in a part, which is assigned to the DHCPv6 relay agent, of the prefix pool, the requesting router prefix routings comprises routings with address prefixes of requesting routers under the DHCPv6 relay agent as destination addresses, and the aggregated routing of requesting router prefix routings comprises a routing with the aggregated prefix as a destination address.

An apparatus for implementing routing aggregation, comprising circuits configured to:

• receive a message, and
• generate an aggregated routing of requesting router prefix routings according to aggregated routing destination address information in the message, wherein the apparatus comprises one of a plurality of Dynamic Host Configuration Protocol version 6 (DHCPv6) relay agents, the prefix pool comprises a plurality of address prefixes and is divided into a plurality of parts which are assigned to the plurality of DHCPv6 relay agents, the prefix pool is shared by a plurality of requesting routers under the plurality of DHCPv6 relay agents, the aggregated routing destination address information comprises part of the information about the prefix pool, and the requesting router prefix routings comprise routings with address prefixes of requesting routers under the apparatus as destination addresses, and the aggregated routing of requesting router prefix routings comprises a routing with the aggregated prefix as a destination address.
