RIP Routing On 4 Routers – VLSM
Given Network: 192.168.0.0
1) Required hosts on Router 1= 100
2) Required hosts on Router 2= 30
3) Required hosts on Router 3= 6
4) Required hosts on Router 4= 1
R1<= 100
100<= 2n – 2
100<= 27 – 2
100<= 128 – 2
100<= 126
Total number of network bits = 32
32 – n = 32 – 7 = 25 (CIDR value of given network i.e. Router 1)
i.e. 192.168.0.0/25
N.S.M = 11111111. 11111111. 11111111.10000000
= 255.255.255.128
Block Size = 256 – N.S.M
= 256 – 128 = 128
Note: Add this block size in given network so that we can get our new network for Router 2.
So the new network is 192.168.0.128/?
Now find FVH, LVH and Broadcast address

30<= 2n – 2
30<= 25 – 2
30<= 32 – 2
30<= 30
Total number of network bits = 32
32 – n = 32 – 5 = 27 (CIDR value of given network i.e. Router 2)
i.e. 192.168.0.128/27
N.S.M = 11111111. 11111111. 11111111.11100000
= 255.255.255.224
Block Size = 256 – N.S.M

i.e. 192.168.0.160/29
N.S.M = 11111111. 11111111. 11111111.11111000
= 255.255.255.248
Block Size = 256 – N.S.M
= 256 – 248 = 8
