This document describes configuring VLANs on switches in a mesh network topology using Cisco Packet Tracer. VLANs are configured to separate devices into two VLANs ("Even" and "Odd") based on whether the last digit of their IP addresses is even or odd. The configuration of each switch involves creating the VLANs, assigning access ports to VLANs based on connected device IP addresses, and configuring trunk ports between switches to allow VLAN traffic.

2. Virtual Local Area Networks (VLAN):-
In a traditional LAN, workstations are connected to each other by means of a hub or a repeater.
These devices propagate any incoming data throughout the network. However, if two people
attempt to send information at the same time, a collision will occur and all the transmitted data
will be lost. Once the collision has occurred, it will continue to be propagated throughout the
network by hubs and repeaters. The original information will therefore need to be resent after
waiting for the collision to be resolved, thereby incurring a significant wastage of time and
resources. To prevent collisions from traveling through all the workstations in the network, a
bridge or a switch can be used. These devices will not forward collisions, but will allow
broadcasts (to every user in the network) and multicasts (to a pre-specified group of users) to
pass through. A router may be used to prevent broadcasts and multicasts from traveling through
the network.
The workstations, hubs, and repeaters together form a LAN segment. A LAN segment is also
known as a collision domain since collisions remain within the segment. The area within which
broadcasts and multicasts are confined is called a broadcast domain or LAN. Thus a LAN can
consist of one or more LAN segments. Defining broadcast and collision domains in a LAN
depends on how the workstations, hubs, switches, and routers are physically connected together.
This means that everyone on a LAN must be located in the same area (see Figure1).
Figure 1: Physical view of a LAN
VLAN's allow a network manager to logically segment a LAN into different broadcast domains
(see Figure2). Since this is a logical segmentation and not a physical one, workstations do not

3. have to be physically located together. Users on different floors of the same building, or even in
different buildings can now belong to the same LAN.

VLAN's also allow broadcast domains to be defined without using routers. Bridging software is
used instead to define which workstations are to be included in the broadcast domain. Routers
would only have to be used to communicate between two VLAN's.

4. Mesh topology
A network setup where each computer and network device is interconnected with one another,
allowing for most transmissions to be distributed, even if one of the connections go down. This
topology is not commonly used for most computer networks as it is difficult and expensive to
have redundant connection to every computer. However, this topology is commonly used for
wireless networks. Below is a visual example of a simple computer setup on a network using a
mesh topology.
A mesh topology can be a full mesh topology or a partially connected mesh topology.
In a full mesh topology, every computer in the network has a connection to each of the other
computers in that network. The number of connections in this network can be calculated using
the following formula (n is the number of computers in the network): n(n-1)/2
In a partially connected mesh topology, at least two of the computers in the network have
connections to multiple other computers in that network. This is a cheaper way to build a
network that has some redundancy in the event one of the primary computers or connections in
the network were to be down.
Description:-
In this Open-Ended Problem we have design VLAN on Cicso packet Tracer. Switch0, Switch1,
Switch2, Switch3 and Switch4 are connected in mesh topology. Three PCs are connected with
every switch 0-4. In this problem VLAN is design on based on its IP address. If last pair in
dotted decimal formal IP address is odd then it is in VLAN 3 named ‘Odd’. If last pair in dotted
decimal formal IP address is even then it is in VLAN 2 named ‘Even’.
