A method and apparatus for generating a forwarding table includes: a control entity generating forwarding entries and setting the forwarding entries having an association attribute in the same associated forwarding entry group; when a forwarding entity queries forwarding entries, after the corresponding forwarding entries are found, the control entity further judging whether the found forwarding entries belong to an associated forwarding entry group, and if yes, the control entity transmitting to the forwarding entity that queries the forwarding entries all the forwarding entries in the associated forwarding entry group which the found forwarding entries belong to. The present invention also forwards the other forwarding entries of the associated forwarding entry group to the forwarding entity correspondingly, when one forwarding entry of the same associated forwarding entry group is forwarded to the forwarding entity. With this method, the times of the forwarding entity transmitting the data message to the control entity, generating a forwarding table or searching the forwarding table is reduced efficiently, and the processing pressure of generating a forwarding table on the control entity is reduced. |
