* A note about virtual-reassembly. Virtual-reassembly causes the router to internally reassemble fragmented packets. It is enabled when an interface is configured with NAT, CBAC, or “ip virtual reassembly”. Operations above marked with a * will process the reassembled version of a packet. All other operations process the individual fragments.
