Configuring a simple LAN on Packet Tracert
Description Figure 1:
A company building two floors, each floors have about 50 computers, the company wants to implement a LAN with cost can purchase the following equipment:
1 | 1 Cisco layer3 switch |
2 | 5 Cisco Layer 2 switch |
3 | 01 ADSL Internet connection |
4 | 02 Access Point |
5 | Internal Server 03 |
You design the VLAN, IP planning, routing on the network to ensure the confidentiality, easily troubleshoot the error, small broadcast domain for fast network speeds but temporarily less complexity.
Requirements on, I would suggest design following on Packet Tracert (in models used represent 2 switch and a PC, laptop):
The diagram above we plan to conduct the IP address as follows:
floors 1: The PC and Wireless IP range 172.16.1.x / 24
floors 2: The receiving PC and Wireless IP range 172.16.2.x / 24
2 floors receive IP from the DHCP server in the Server area;
Areas receiving server IP range 172.16.3.x / 24; This set static IP area
The configuration steps:
– On the first floor default L2 switch has VLAN 1 and VLAN port belongs should have done
– On the second floor L2 switch, we create VLAN 2 and put the port belong to this VLAN 2
– On the L2 switch in the server room to create VLAN 3, and put the port in this VLAN
At Layer 3 Switch, create VLAN 2 and VLAN 3, and set the IP address for the VLAN corresponding to the server room floors are:
+ VLAN 1: 172.16.1.1/24
+ VLAN 2: 172.16.2.1/24
+ VLAN 3: 172.16.3.1/24
+ VLAN 4: 192.168.1.2/24
And on each VLAN interface of our forwards DHCP requests to the DHCP server in the server room with IP helper-address command
– Routing for the VLAN on the switch with Layer 3 IP routing command in global mode
– Routing default route to ADSL
Configuration details:
+ In the 1st floor switch:
At this switch to the default one for VLAN 1 has been created and all ports are in VLAN 1 is
+ In the 2nd floor switch:
Create VLAN 2 and put all ports in VLAN 2
Switch (config) #vlan 2
Switch (config) #name tang2
Switch (config) #switchport access vlan 2
+ The switch server:
Create VLAN 3 and put all ports in VLAN 3
Switch (config) #vlan 3
Switch (config) #name server
Switch (config) #switchport access vlan 3
+ At layer3 switch:
Step 1: Create the VLAN 2,3,4
Switch (config) #vlan 2
Switch (config-vlan) #
Switch (config-vlan) #name tang2
Switch (config-vlan) #vlan 3
Switch (config-vlan) #name server
Switch (config-vlan) #vlan 4
Switch (config-vlan) #name ADSL
Switch (config-vlan) #
Step 2: IP set for the VLAN
Switch# conf terminal
Enter configuration commands, one per line. End with Cntl / Z.
Switch (config)#interface vlan 1
Switch (config-if)#ip address 172.16.1.1 255.255.255.0
Switch (config-if) #no shutdown
Switch (config-if) #
Switch (config-if) #interface vlan 2
Switch (config-if)#ip address 172.16.2.1 255.255.255.0
Switch (config-if)#no shutdown
Switch (config-if)#int erface vlan 3
Switch (config-if)#ip address 172.16.3.1 255.255.255.0
Switch (config-if)#no shutdown
Switch (config-if)#interface vlan 4
Switch (config-if)#ip address 192.168.1.2 255.255.255.0
Switch (config-if) #no shutdown
Step 3: Enable Routing
Switch (config)#ip routing
Step 4: Routing over IP Default route of ADSL
Switch (config) #ip route 0.0.0.0 0.0.0.0 192.168.1.2
Step 5: Insert the port f0 / 4 in VLAN 4
Switch (config)#interface f0 /4
Switch (config-if)#switchport access vlan 4
Step 6: Trunk port f0/1 -f0/3 (in this article might not need this trunk ports by putting the port corresponding to the switch to the appropriate VLAN, but for our future there may be multiple layer 2 VLAN on the switch again to the overall solution should Trunk of ports)
Switch (config-if-range)#interface range f0 1-3
Switch (config-if-range) trunk encapsulation dot1q #switchport
Switch (config-if-range)#switchport trunk
Step 7: Forward DHCP request to the DHCP server in the room for VLAN 1 and 2
Switch (config) #int vlan 1
Switch (config-if) #ip helper-address 172.16.3.2
Switch (config-if) #int vlan 2
Switch (config-if) #ip helper-address 172.16.3.2
Step 8: Record configuration
Switch # write memory
+ At the ADSL Router: We need more static route on the VLAN routing 1,2,3
Switch (config) #ip route 172.16.0.0 255.255.0.0 192.168.1.2
+ The DHCP server we configure ip range as shown
+ Also the IP configuration, the configuration you like on the map
The results of the PC and laptop computer to the Internet ping 203.162.0.2 as follows:
