~Study RTO , DU, Reply~ 13/feb/2013

REPLY

RTO = Request Time Out 

DU = Destination Unreachable


Bismillahirahmanirahim .... 


A : 192. 168.  1.    2 /24

     255. 255. 255. 0

B : 192. 168.   2.   3/24
     255. 255. 255. 0

So " A - B = DU" "B - A = DU"
kerana bla subnet 255 ip  A n B kna sma.. cm condition kt atsa d mana kt oktel ke 3 'A' = 1, 'B' = 2, 
A - B = DU , B - A = DU ,

tp bila ip cm ne 

A : 192. 168. 1. 2 /16
     255. 255. 0. 0

B : 192. 168.2.3/16
      255.255.0.0

So "(A - B)(B - A) = REPLY" 
Kerana bla subnet 0 ip A n B xsma pun dy bole trima .

lg...

A : 192.168.1.2 / 16
      255.255.0.0

B : 192.168.2.3 / 24
     255.255.255.0

"A - B = RTO" n  "B - A = DU" kerana bla A ping ke B , boleh tetapi B nk reply x boleh.. so RTO , 
B ping ke A ^DU^ kerana oktel ke 3 pd A = 1, B = 2. d sbbkn subnet dy 255 B - A so, DU.

tp ini pun ble jd RTO

A : 192.168.1.2/24
B : 192.168.1.3/24
hal ini berlaku kerana PC OFF, Network x On..hehe n so on...

 haa... alhamdulillah setakat ne je y saya fhm n bole kongsi ngan korg :)
