RIP Configuration of 4 Routers – Advance LAB

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

VLSM

Given Network: 210.80.50.0

Required hosts on Router 1= 50

Required hosts on Router 2= 25

Required hosts on Router 3= 14

Required hosts on Router 4= 5

RIP Configuration of 4 Routers - Advance LAB

R1<= 50

50<= 2n – 2

50<= 26 – 2

50<= 64 – 2

50<= 62

Total number of network bits = 32

32 – n = 32 – 6 = 26 (CIDR value of given network i.e. Router 1)

i.e. 210.80.50.0/26

N.S.M = 11111111. 11111111. 11111111.11000000

                        = 255.255.255.192

Block Size        = 256 – N.S.M

                        = 256 – 192 = 64

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

So the new network is 210.80.50.64/?

Now find FVH, LVH and Broadcast address
