This is the eleventh day of my participation in the Gwen Challenge in November. Check out the details: The last Gwen Challenge in 2021
Communication between different vlans
I. Purpose of the experiment
Understand and master the functions, creation and use of VLAN;
Understand and master communication Layer 3 switches enable communication between vlans.
Second, network topology
The network topology of an enterprise is shown in Figure 1.
The Server is connected to the FastEthernet 0/1 interface in layer 3 SWITCH S3.
GigabitEthernet 0/0/1 of Layer 2 switch S1 is connected to GigabitEthernet 0/0/1 of Layer 3 switch.
GigabitEthernet 0/2 of layer 2 switch S2 is connected to GigabitEthernet 0/2 of Layer 3 switch.
3. Configuration planning
(1) VLAN configuration planning:
| VLAN ID | Network segment | The default gateway |
|---|---|---|
| 10 | 192.168.10.0/24 | 192.168.10.254 |
| 20 | 192.168.20.0/24 | 192.168.20.254 |
| 30 | 192.168.30.0/24 | 192.168.30.254 |
| 40 | 192.168.40.0/24 | 192.168.40.254 |
(2) VLAN description
VLAN 10: The primary allocation is server use. Ports FastEthernet 0/1 to FastEthernet 0/10 on layer 3 switches are assigned to VLAN 10
VLAN 20: all PCS in this VLAN connect to Layer 2 switch S1, which connects to Layer 3 switch GigabitEthernet 0/0/1.
VLAN 30: Assign the FastEthernet 0/1 to FastEthernet 0/10 ports of layer 2 switches to VLAN 30.
VLAN 40: Assign ports FastEthernet 0/11 to FastEthernet 0/20 of layer 2 switches to VLAN 40.
4. Practice tasks
This section describes the configuration on each switch to enable the communication between the four vlans.
Server-pt Server 0 is configured as follows:
Configure fastethernet0/1-10 ports for VLAN 10 and VLAN 30 and VLAN 40.
IP configuration for PC0, PC1, and PC2:
PC0 Ping server Server (VLAN10 communicates with VLAN20) :
PC0 Ping PC1 (VLAN20 communicates with VLAN30) :
