RIP Configuration on 4 Routers – Advance LAB

In this lab, I am gonna teach you RIP Configuration on 4 Routers.

VLSM

Given Network: 197.100.100.0

Required hosts on Router 1= 30

Required hosts on Router 2= 25

Required hosts on Router 3= 6

Required hosts on Router 4= 1

RIP Configuration on 4 Routers

R1<= 30

30<= 2n – 2

30<= 25 – 2

30<= 32 – 2

30<= 32

Total number of network bits = 32

32 – n = 32 – 5 = 27 (CIDR value of given network i.e. Router 1)

i.e. 197.100.100.0/27

N.S.M = 11111111. 11111111. 11111111.11100000

                        = 255.255.255.224

Block Size        = 256 – N.S.M

                        = 256 – 224 = 32

Note: Add this block size in given network so that we can get our new network for Router 2.

So the new network is 197.100.100.32/?

Now find FVH, LVH and Broadcast address
