What is subnetting and supernetting and its uses?

Answer Posted / jitendera

Ok Pandi

I have one question for you and all of you guys

if Subneting is something like breaking a Single block of ip
in the multiple block of ip address and Suppernating is
combining the Multiple ip block in to single block am i wrong ?

Now the Question is that

i am using a Routing protocol say eigrp

and i am configuring like

router eigrp 100
network 10.10.10.0 0.0.0.0.255
network 10.10.20.0 0.0.0.0.255
network 10.10.30.0 0.0.0.0.255


now if i make the command
show ip route

it will show

10.0.0.0/16 has been thorugh EIGRP and there will no entry
of 10.10.20.0 and 10.10.30.0

1) So what i have to do so that the all three subnet show
in routing table-- quite simple think and answer

2) if you get the answer then tell me at last what is the
difference between Subnating and suppernating

Think like genius not like me :-)
