An apparatus and method for processing IP packet fragmentation in a routing system using a network processor includes an ingress network processor receiving a packet, and if the received packet is greater than MTU, fragmenting the packet rather than sending the packet to a control processor to fragment the packet. All packets are processed using a fragmentation-based packet-processing method as a result of packet encapsulation, which is caused for mobility support in an IPv4 router. In addition, all the packets are processed by micro-engines, a data plane processor, irrespective of whether fragmentation is to be performed. Accordingly, the same packet-processing rate can be supported to mobile nodes irrespective of mobility or packet size.
