VTP Lab 1

Question:
The headquarter offices for a book retailer are enhancing their wiring closets with Layer3 switches. The new distribution-layer switch has been installed and a new access-layer switch cabled to it. Your task is to configure VTP to share VLAN information from the distribution-layer switch to the access-layer devices. Then, it is necessary to configure interVLAN routing on the distribution layer switch to route traffic between the different VLANs that are configured on the access-layer switches; however, it is not necessary for you to make the specific VLAN port assignments on the access-layer switches. Also, because VLAN database mode is being deprecated by Cisco, all VLAN and VTP configurations are to be completed in the global configuration mode. Please reference the following table for the VTP and VLAN information to be configured:

Requirements:
VTP Domain name cisco
VLAN Ids 20 21 IP Addresses 172.16.71.1/24 172.16.132.1/24 These are your specific tasks:
1. Configure the VTP information with the distribution layer switch as the VTP server
2. Configure the VTP information with the access layer switch as a VTP client
3. Configure VLANs on the distribution layer switch
4. Configure inter-VLAN routing on the distribution layer switch
5. Specific VLAN port assignments will be made as users are added to the access layer switches in the future.
6. All VLANs and VTP configurations are to completed in the global configuration. To configure the switch click on the host icon that is connected to the switch be way of a serial console cable.
Answer and Explanation:



1) Configure the VTP information with the distribution layer switch as the VTP server:


DLSwitch#configure terminal
DLSwitch(config)#vtp mode server
DLSwitch(config)#vtp domain cisco (use cisco, not CISCO because it is case sensitive)
(Requirement 2 will be solved later)
3) Configure VLANs on the distribution layer switch
To create VLANs on a switch, use the vlan vlanID# command:
DLSwitch(config)#vlan 20
DLSwitch(config)#vlan 21
Configure Ip addresses for Vlans:
DLSwitch(config)#interface vlan 20
DLSwitch(if-config)#ip address 172.16.71.1 255.255.255.0
DLSwitch(if-config)#no shutdown
DLSwitch(if-config)#interface vlan 21
DLSwitch(if-config)#ip address 172.16.132.1 255.255.255.0
DLSwitch(if-config)#no shutdown
DLSwitch(if-config)#exit
4) Configure inter-VLAN routing on the distribution layer switch

DLSwitch(config)#ip routing
DLSwitch(config)#exit
DLSwitch#copy running-config startup-config
2) Configure the VTP information with the access layer switch as a VTP client
ALSwitch#configure terminal
ALSwitch(config)#vtp mode client
ALSwitch(config)#vtp domain cisco
ALSwitch(config)#exit
ALSwitch#copy running-config startup-config
(Notice: Many reports said the copy running-config startup-config didn’t work but they still got the full mark)
