Abstract
Information packets are routed through a distributed routing network by determining a forwarding equivalency class (FEC) for each subscriber unit accessing the network. The FEC to which each subscriber unit belongs is based on the point at which the subscriber unit accesses the network. The forwarding equivalency class for each subscriber unit is updated if the subscriber unit accesses the network at a different point. Information packets are routed from a distribution point by determining the next point connected to the distribution point based on the forwarding equivalency class for the destination subscriber unit specified in the packet.
