The present invention provides a method for creating routes in access devices of the communication network by using access response messages. With the method provided by the present invention, services can be distinguished and forwarded based on destination IP sub-networks, so that different services can be distributed in access devices. In this way, on the premise that services are distinguished based on layer 3, the requirements for access devices are reduced and layer 2 networks on the user side are not required to carry out route protocols, which decreases administrators' maintenance work and is the important condition for the realization of plug&play and reduces the requirements for marginal routers.
