Packet Tracer Lab 2 - Inter-VLAN Routing

VLAN stands for Virtual Local Area Network. It is usually configured on switches to divide a physical LAN into multiple broadcast domains. 

For example, all teachers' computers in a school could be assigned to the "Teacher" VLAN, while all students' computers could be assigned to the "Student" VLAN. In this way, VLANs can improve the efficiency and flexibility of a local area network.

We need a device that can do routing to communicate the computers on separate VLANs. Inter-VLAN routing is a process to forward network traffic from one VLAN to another VLAN using a router.

In this lesson, we will demonstrate how to configure VLAN and setup a router to enable the inter-VLAN routing.

We have 3 VLANs: VLAN10, VLAN20 and VLAN30, as shown in figure below.

In this demonstration, Port Fa0/1 of S1 and S2 will be configured as access port and VLAN 10.

Port Fa0/6 of S1 and S2 will be configured as access port and VLAN 20.

Port Fa0/11 of S1 and S2 will be configured as access port and VLAN 30.

G0/1 and G0/2 of S1 and S2 will be configured as trunk port, only traffic from VLAN10, VLAN20 and VLAN30 can be allowed to pass through.

This is the IP address we need to configure in every device.
