Never is a strong word. It seems "ip virtual-reassembly" do it. It looks
like it at least reassembles them in memory and delays them before
forwarding them (as fragments) from the debug and counters. On a
virtual 7200:
Router#show ip virtual-reassembly fa1/0
FastEthernet1/0:
Virtual Fragment Reassembly (VFR) is ENABLED...
Concurrent reassemblies (max-reassemblies): 16
Fragments per reassembly (max-fragments): 32
Reassembly timeout (timeout): 3 seconds
Drop fragments: OFF
Current reassembly count:0
Current fragment count:0
Total reassembly count:23
Total reassembly timeout count:3
Not that you'd want to do it, but still.
