Re: HELP!!!!!! %IP_VFR-4-FRAG_TABLE_OVERFLOW:

The router is saying to you that the max concurent reassemblies supported is
16 and the error you get is that you have reached that limit: *Concurrent
reassemblies (max-reassemblies): 16
*you can* *say no ip virtual-reassembly under the interface as you most
probebly have a lot of fragments in your lab.

or the other solution is to increase the amount of frag

* ip virtual-reassembly max-reassemblies 32 max-fragments 64 time 5*
**
*do sh ip virtual-reassembly f0/0*
**
