CORRECT TEXT
A new switch is being added to the River Campus LAN. You will work to complete this process by first
configuring the building_2 switch with an IP address and default gateway. For the switch host
address, you should use the last available IP address on the management subnet. In addition, the
switch needs to be configured to be in the same VTP domain as the building_1 switch and also needs
to be configured as a VTP client. Assume that the IP configuration and VTP configuration on
building_1 are complete and correct. The configuration of the router is not accessible for this
exercise. You must accomplish the following tasks:
Determine and configure the IP host address of the new switch. Determine and configure the default
gateway of the new switch. Determine and configure the correct VTP domain name for the new
switch.
Configure the new switch as a VTP client.
Answer: See the explanation
Explanation:
Here are the Steps for this Lab Solution:
The question states we can’t access the router so we can only get required information from switch
building_1. Click on the PC connected with switch building_1 (through a console line) to access
switch building_1s CLI. On this switch use the show running-config command: building_1#show
running-config Next use the show vtp status command to learn about the vtp domain on this switch
building_1#show vtp status (Notice: the IP address, IP default-gateway and VTP domain name might
be different!!!) You should write down these 3 parameters carefully. Configuring the new switch
+ Determine and configure the IP host address of the new switch The question requires “for the
switch host address, you should use the last available IP address on the management subnet”. The
building_1 switch’s IP address, which is 192.168.22.50 255.255.255.224, belongs to the management
subnet. Increment: 32 (because 224 = 1110 0000) Network address: 192.168.22.32 Broadcast
address: 192.168.22.63 ->The last available IP address on the management subnet is 192.168.22.62
and it hasn’t been used (notice that the IP address of Fa0/1 interface of the router is also the default
gateway address 192.168.22.35). Also notice that the management IP address of a switch should be
configured in Vlan1 interface. After it is configured, we can connect to it via telnet or SSH to manage
it. Switch2#configure terminal Switch2(config)#interface Vlan1 Switch2(config-if)#ip address
192.168.22.62 255.255.255.224 Switch2(config-if)#no shutdown (not really necessary since VLAN
interfaces are not physical and are not shut down but, no harm in doing so and is good practice for
physical ports)
+ Determine and configure the default gateway of the new switch The default gateway of this new
switch is same as that of building_1 switch, which is 192.168.22.35 Switch2(config-if)#exit
Switch2(config)#ip default-gateway 192.168.22.35
+ Determine and configure the correct VTP domain name for the new switch The VTP domain name
shown on building_1 switch is Cisco so we have to use it in the new switch (notice: the VTP domain
name will be different in the exam and it is case sensitive so be careful) Switch2(config)#vtp domain
Cisco + Configure the new switch as a VTP client Switch2(config)#vtp mode client We should check
the new configuration with the “show running-config” & “show vtp status”; also try pinging from the
new switch to the the default gateway to make sure it works well. Finally save the configuration:
Switch2(config)#exit Switch2#copy running-config startup-config
