 error_burst and error_cost
 --------------------------
 
-These parameters  are used to limit the warning messages written to the kernel
-log from  the  routing  code.  The  higher the error_cost factor is, the fewer
-messages will  be written. Error_burst controls when messages will be dropped.
-The default settings limit warning messages to one every five seconds.
+These  parameters  are used to limit how many ICMP destination unreachable to 
+send  from  the  host  in question. It will also print some error messages to 
+kernel  logs  if  someone  is  ignoring  our  ICMP  redirects. The higher the 
+error_cost  factor  is,  the fewer destination unreachable and error messages 
+will  be  let  through.  Error_burst  controls  when  destination unreachable 
+messages  and  error  messages  will  be  dropped. The default settings limit 
+warning messages to five every second.
