Variable‐Length Subnet Masking (VLSM) amounts to "subnetting subnets", which means that VLSM allows
network engineers to divide an IP address space into a hierarchy of subnets of different sizes, making it possible
to create subnets with very different host counts without wasting large numbers of addresses (techtarget, 2014).
Based on your practice activities in the lab, complete the following tasks;
Task 1:
You have been allocated the IP address range XXXXXXXXXX/24. You have to subnet this allocation using VLSM. You
have the following network;
LAN1 requires 20 IP addresses.
LAN2 requires 40 IP addresses.
LAN3 requires 50 IP addresses.
R1 is connected to both LAN1 and R2.
R2 is connected to R1, R3 and LAN2.
R3 is connected to R2 and LAN3.
Write out a VLSM subnet allocation in the following table:
Network Identity Address Mask 1st Usable Address
Last Usable
Address
Broadcast Address
LAN1
LAN2
LAN3
R1 to R2
R2 to R3

R2 s0/0/1 connected to R1

Addresses some elements of performance evidence and
knowledge evidence as shown in the Assessment Matrix
Description:
In business enterprises or educational institutions, routers are typically used to connect two or more subnets,
each with a different sub‐network address. Routers may provide connectivity within enterprises, between
enterprises and the Internet, or between internet service providers' (ISPs) networks; and are available in various
sizes.
In this scenario‐based task, you will assume the role of an IT Network Administrator working in an IT consulting
firm. The firm provides network design,
