摘要： A method for allocating network addresses comprises providing an address pool comprising a plurality of network addresses and then dividing the address pool into a plurality of address sub-pool that comprise a unique subset of the network addresses of the address pool. Each of the sub-pools is available for use by any one of a plurality of routing devices of a network access server. The method then comprises receiving a request to assign a first network address to a first user, allocating a first address sub-pool of the plurality of address sub-pools to a first routing device of the plurality of routing devices and transmitting a first message to the other routing devices to indicate that the first address sub-pool has been allocated. The method additionally comprises assigning the first network address to the first user from the first address sub-pool and advertising an aggregate route for the first address sub-pool over a network.
