Answer / pandi
subnetting used to divide a network into multiple networks.
but, supernetting used to a add multiple network into a
same network.

Answer to this Question
So what i have to do so that the all three subnet show
in routing table-- quite simple think and answer.

Answer / 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 :-)

A subnet mask is used to identify which parts of the ip
address are the network parts and which parts are the host
parts.
e.g
IP 192.168.1.10
Subnet mask : 255.255.255.0
This indicates that the first 3 parts of the IP address are
used to identify the Network.
Let's take a class C mask of 255.255.255.0 - If we borrow 2
network bits, the mask changes to 255.255.252.0, this is
called Supernetting. If on the other hand we borrow two host
bits, the mask changes to 255.255.255.192, this is called
subnetting.
Supernetting therefore allows you to have more hosts on one
network, whilst subnetting allows you to have more inter
networks but with less hosts.
.... So without subnetting or supernetting these two
addresses would be on same network:
IP 192.168.1.10
Subnet mask : 255.255.255.0
IP 192.168.1.233
Subnet mask : 255.255.255.0
With Subnetting, we have borrowed one bit (from the host
part) which in binary looks like this 1000000, now this
splits the network into two networks so these addresses are
now on different networks.
IP 192.168.1.10
Subnet mask : 255.255.255.128
IP 192.168.1.233
Subnet mask : 255.255.255.128
With Supernetting, we borrow one bit from the network part
so the last two parts of subnet mask now look like this
11111110.00000000. These two are on the same network now
because the number of host addresses has increased.
IP 192.168.1.10
Subnet mask : 255.255.254.0
IP 192.168.2.125
Subnet mask : 255.255.254.0
