Hi Jitendera

Kapil on this side I will try to explain

See

Two method u know very well. 3rd is like that

Suppose we have route in router area 1 is

192.168.1.0
192.168.2.0
192.168.3.0
192.168.4.0
192.168.5.0
192.168.6.0

Now we convert 3rd bit in binary
128 64 32 16 8 4 2 1

192.168.00000001.0
192.168.00000010.0
192.168.00000011.0
192.168.00000110.0
192.168.00000101.0
192.168.00000110.0

Now make a mask.
192(8bit).168(8bit).5bit(see zero).0

Now the 1 to 6 route ip is 192.168.0.0

And mask is 255.255.248(5bit of binary).0
Now the wild make is 0.0.7.255

Now the route of ospf is

Network 192.168.0.0 0.0.7.255


sorry if any thing i forgot to tell....
