Hi,

From RFC792, 

Type 11 = Time Exceeded Message
Code  0 = time to live exceeded in transit

Every time a packet passes through a gateway the TTL value is decremented by one
second. When it reaches zero the gateway must discard the packet and may then 
send this ICMP message back to the source host. But read the rfc.

Best Regards
Willem Brown
