Experiment six using three-layer switch to implement inter-VLAN routing

experiment six using three-layer switch to implement inter-VLAN routing

First, the experimental target

1. Mastering the configuration of the switch tag VLAN
2. Master three layer switch basic configuration method;
3. Master three-layer switch VLAN routing configuration method;
4. Inter-VLAN communication through three layer switch;

Second, the experimental background

An enterprise has two major departments, technical department and sales department, divided into different offices, in order to secure and easy to manage the two departments of the Host VLAN division, the technical department and the sales section in different VLANs, first because the business needs of the sales department and the technical Department of the host can access each other, access to the corresponding resources, The switches in both departments are connected through a three-layer switch.

Three, the principle of technology

Layer three switch has the function of network layer, realize VLAN mutual access principle is: Using the routing function of three layer switch, by identifying the IP address of the packet, finding the route table for routing and forwarding, the three layer switch can realize mutual access between different VLANs by using the Direct connect route. The layer three switch configures the IP address for the interface. The use of SVI (Exchange Virtual Interface) to achieve inter-VLAN interconnection. SVI refers to creating a virtual interface for the VLAN in the switch and configuring the IP address.

Iv. Steps of the experiment

(1) New Packet tracer topology diagram

(2) in the two-layer switch configuration VLAN2, VLAN3, respectively, Port 2, Port 3 is divided into VLAN2, VLAN3.

(3) The Port FA 0/1 connected to the two-layer switch and the three-layer switch is defined as the Tag VLAN mode.

(4) Configure the VLAN2, VLAN3 on the three-layer switch to verify that the two-layer switch VLAN2, the host under VLAN3, cannot communicate with each other.

(5) Set up the communication between the three layer switch VLAN, create the virtual interface of VLAN2,VLAN3, and configure the IP address of virtual interface VLAN2, VLAN3.

(6) View the three Layer switch routing table.

(7) Set the two layer switch VLAN2, the host default gateway under VLAN3 to the IP address of the corresponding virtual interface respectively.

(8) Verify that the hosts under Layer Two switch vlan2,valn3 can communicate with each other.

Viii. Experimental Results

1. Configure IP addresses for PC0, PC1, PC2

2. Configure VLAN2, VLAN3 on Layer Two switch, divide Port 2, Port 3 to VLAN2, VLAN3 respectively. The Port FA 0/1, which connects the two-layer switch to the three-layer switch, is defined as the Tag VLAN mode.

3.s3560, configure VLAN2, VLAN3 on the three-layer switch to verify that the two-layer switch VLAN2, the hosts under VLAN3, cannot communicate with each other. Set up communication between the three-layer switch VLAN, create a virtual interface for VLAN2,VLAN3, and configure the IP address of the virtual interface VLAN2, VLAN3.

4. Verify that the hosts under the switch can communicate with each other
