<p>The present invention provides a route aggregation method which is applied to a network comprising at least one Autonomous System Border Router (ASBR), each ASBR is connected to at least one Provider Edge (PE), the method includes: the ASBR receiving a plurality of original routes from the PE, aggregating the original routes which have a same Route Distinguisher (RD) and belong to a same sub-network, generating aggregated routes, distributing a label to each aggregated route, and adding the label into the aggregated route, generating an aggregated route with the label. The routes which are received and stored by the Autonomous System Border Router are reduced by using the present invention, and the burden of forwarding the routes is also reduced. Simultaneously, the present invention also provides a method for forwarding messages and an Autonomous System Border Router, and the routes which are received and stored by the Autonomous System Border Router are effectually reduced, so as to reduce the number of the routes in the whole network.</p> |
