Lesson No. 20 Introduction to VLAN and configure the topology using VLAN.

Description: In computer networking, a single layer-2 network may be partitioned to create multiple distinct broadcast domains, which are mutually isolated so that packets can only pass between them via one or more routers; such a domain is referred to as a Virtual Local Area Network, Virtual LAN or VLAN.

Solution: The given topology is:

Steps:

Configuring steps for PC0:

Ip address: 10.0.0.1

Subnet mask: 255.255.255.0

Configuring steps for PC1:

Ip address: 10.0.0.2

Subnet mask: 255.255.255.0

Configuring steps for PC2:

Ip address: 10.0.0.3

Subnet mask: 255.255.255.0

Configuring steps for PC3:

Ip address: 10.0.0.4

Subnet mask: 255.255.255.0

Configuring steps for PC4:

Ip address: 10.0.0.5

Subnet mask: 255.255.255.0

Configuring steps for switch0:

Switch>enable

Switch#config terminal

Switch(config)#vlan 2

Switch(config-vlan)#name sales

Switch(config-vlan)#interface range fa0/1 – fa0/2

Switch(config-if-range)# switchport mode access

Switch(config-if-range)#switchport access vlan 2

Switch(config-if-range)#exit

Switch(config)#exit

Output:
