The purpose of this lab is to help you understand basic router and switch configuration, as well as the purpose of these devices. It will cover the OSI model, and what layer different technologies are in on that model.
Your goal for this lab is to configure a fully routed network so that each device can communicate with every other device.
Basic Device Configuration
When starting a lab, there are some basic things that will need to be done on every device. The following should be done at the start of every lab:
Configure the device hostname
Disable domain-name lookup
Configure password encryption
Set console timeout
Configure “logging synchronous” on the console line
Configure passwords
Important: When configuring passwords on any lab, on any device, always use ‘ccie’.
Here is an example from router R1:
Router>
Router>enable
Router#config
Configuring from terminal, memory, or network [terminal]? t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname R1
R1(config)#no ip domain-lookup
R1(config)#service password-encryption
R1(config)#enable secret ccie
R1(config)#line con 0
R1(config-line)#exec-timeout 0 0
R1(config-line)#password ccie
R1(config-line)#logging synchronous
Using the example above as a guide, do the basic device configuration on the remaining devices in your pod.
Interface Configuration
To start, shut down all unused interfaces on the switches. To do this, use the interface range command, and the shutdown command.
CAT1(config)#interface range fa0/1 - 24
CAT1(config-if-range)#shutdown
CAT1(config-if-range)#

VLAN Trunks Between Switches
To configure a trunk between two switches, use the switchport trunk encapsulation dot1q command, the switchport trunk allowed vlan command, and the switchport mode trunk command.
CAT1(config)#interface fa0/19
CAT1(config-if)#switchport trunk encapsulation dot1q
CAT1(config-if)#switchport trunk allowed vlan 12,16,23,34
CAT1(config-if)#switchport mode trunk
CAT1(config-if)#

4d00h: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/19, changed state to up
Using the example above as a guide, configure the following links as trunks:
CAT1 and CAT3 on ports Fa0/19
CAT3 and CAT4 on ports Fa0/24
CAT4 and CAT2 on ports Fa0/19
Confirmation: Use the show interface trunk command to verify trunking status.

VLAN Trunking Protocol (VTP)
VTP is a layer 2 protocol that is used to propagate VLANs between switches and dynamically negotiate VLAN trunks. VTP uses a server-client model, with one or more switches acting as the server where all changes are made, and zero or more switches acting as read only clients. An active trunk between two switches is needed for VTP information to be propagated. For VTP to work, all switches must be configured with the same domain, VTP version, and password. VTP information is sent on the native VLAN.
To configure a switch as a VTP server, use the vtp mode server, vtp domain, vtp password, and vtp version 2 commands.
CAT3#conf t
Enter configuration commands, one per line. End with CNTL/Z.
CAT3(config)#vtp mode server
Setting device to VTP SERVER mode
CAT3(config)#vtp version 2
CAT3(config)#vtp domain lab2
Changing VTP domain name from NULL to lab2
CAT3(config)#vtp password ccie
Setting device VLAN database password to ccie
To configure a switch as a VTP client, use the vtp mode client, vtp domain, and vtp password commands.
CAT1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
CAT1(config)#vtp mode client
Setting device to VTP CLIENT mode.
CAT1(config)#vtp domain lab2
Changing VTP domain name from NULL to lab2
CAT1(config)#vtp password ccie
Setting device VLAN database password to ccie
VLANs cannot be configured on switches that are in client mode.
CAT2(config)#vlan 12
VTP VLAN configuration not allowed when device is in CLIENT mode.
To configure VLANs on switches configured in server mode use the vlan command.
CAT3(config)#vlan 12,16,23,34
CAT3(config-vlan)#exit
Using the above example, configure CAT3 as a VTP server, and CAT1, CAT2 and CAT4 as VTP clients. Use VTP domain ‘lab2’ and VTP password ‘ccie.’ Configure VLANs 12, 16, 23, and 34 on CAT3.
Confirmation: Use the show vtp status command to verify VTP configuration.

To configure a port to be in a VLAN, use the switchport access vlan command and the switchport mode access command on the switch.
CAT1(config)#interface fa0/3
CAT1(config-if)#switchport access vlan 34
CAT1(config-if)#switchport mode access
Sometimes a router needs to route between more networks then it has interfaces for. To do this, you can set up a trunk between the switch and the router. Just like a trunk between two switches allows multiple networks over the same cable, we can do this between a router and a switch. This is often called a ‘router on a stick.’
To configure a ‘router on a stick,’ configure the switchport just as you would a trunk between two switches.
CAT1(config)#interface fa0/2
CAT1(config-if)#switchport trunk encapsulation dot1q
CAT1(config-if)#switchport trunk allowed vlan 12,23
CAT1(config-if)#switchport mode trunk
CAT1(config-if)#
4d01h: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2, changed state to down
4d01h: %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/2, changed state to up
On the router, use the interface and encapsulation commands. The syntax for the encapsulation command is
encapsulation dot1q <VLAN>
R2#configure t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#interface fa0/0.12
R2(config-subif)#encapsulation dot1q 12
R2(config-subif)#interface fa0/0.23
R2(config-subif)#encapsulation dot1q 23
R2(config-subif)#exit
Notice the additional information on the interface command. This specifies that it is a sub-interface.
Configure all Ethernet ports to be in the correct VLAN. Use the physical and logical diagrams to determine which VLAN each port should be in. Configure the trunks between CAT1 and R2 and CAT2 and R1. Use the sub-interface configuration example above to configure the router’s interfaces.
Confirmation: Use the show vlan brief command to verify VLAN port configuration.

Spanning Tree Protocol (STP)
Spanning Tree Protocol (STP) is a layer 2 protocol used on Ethernet networks to prevent switching loops. Switching loops are undesirable, as they cause flooding of traffic on the network, resulting in an unusable network.
STP works by electing a root switch, then creating a spanning tree from that switch. It then disables the forwarding of traffic on the interfaces that are not part of that tree. Per the definition of a spanning tree, the resulting network will have no loops. By default, there is one instance of spanning tree per VLAN.
By default, spanning tree is configured to run on most every switch sold by default. There are many commands that allow you to modify how the switches calculate the spanning tree. For this lab, we are only going to change which switch gets elected as the root bridge (bridge is another name for a switch).
The way that spanning tree elects a root switch is by using the lowest configured priority on the switches. In case of a tie in priority, it uses the switch with the lowest MAC address.
To configure the root priority of a switch, use the spanning-tree vlan root primary command. The syntax for this command is
spanning-tree vlan <vlan range> root primary
CAT3(config)#spanning-tree vlan 12,16 root primary
This command changes the root priority of that switch for vlans in the <vlan range> to a value of 24576. To manually change the priority of the switch, use the spanning-tree vlan priority command. The syntax for this command is
spanning-tree vlan <vlan range> priority <priority>
CAT4(config)#spanning-tree vlan 23,34 priority 16384
Using the spanning-tree vlan root primary command, configure CAT3 as the spanning-tree root of VLANs 12 and 16. Using the spanning-tree vlan priority command, configure CAT4 as the spanning-tree root of VLANs 23 and 34 with a priority of 16384.
Confirmation: To view spanning-tree information, use the show spanning-tree command.

For the purpose of this lab, we will be using only /24, or 255.255.255.0 networks.
To put an IP address on an interface, use the ip address command. The syntax for this command is
ip address <ip address> <mask>
R1(config)#interface fa0/1.12
R1(config-subif)#ip address 172.16.12.1 255.255.255.0
R1(config-subif)#exit
R1(config)#interface fa0/1.16
R1(config-subif)#ip address 172.16.16.1 255.255.255.0

R3(config-if)#ip address 172.16.34.3 255.255.255.0
R3(config-if)#exit
R3(config)#interface fa0/1
R3(config-if)#ip address 172.16.23.3 255.255.255.0
R3(config-if)#exit
R3(config)#interface s0/1/0
R3(config-if)#ip address 10.0.35.3 255.255.255.0
Using the diagrams, finish addressing the remaining Ethernet and Serial interfaces. Do not configure the interfaces that are connected to the Frame Relay Switch (FRS).
Confirmation: To verify IP addressing, use the show ip interface brief command.

To configure frame relay on a point to point sub-interface, use the frame-relay interface-dlci command.
R2(config)#interface s0/0/0.12 point-to-point
R2(config-subif)#ip address 10.0.12.2 255.255.255.0
R2(config-subif)#frame-relay interface-dlci 201
Using the commands above, configure frame relay on all applicable devices.

At this point in the lab, each router can send data to routers that are adjacent to itself. In this lab we will be configuring the EIGRP routing protocol.
To configure EIGRP, use the router eigrp 1, no auto-summary, and the network commands. The syntax for the network command is
network <network address>
R1(config)#router eigrp 1
R1(config-router)#no auto-summary
R1(config-router)#network 172.16.0.0
R1(config-router)#network 10.0.0.0
R2(config)#router eigrp 1
R2(config-router)#no auto-summary
R2(config-router)#network 172.16.0.0
R2(config-router)#network 10.0.0.0
R3(config)#router eigrp 1
R3(config-router)#no auto-summary
R3(config-router)#network 172.16.0.0
R3(config-router)#network 10.0.0.0
R4(config)#router eigrp 1
R4(config-router)#no auto-summary
R4(config-router)#network 172.16.0.0
R4(config-router)#network 10.0.0.0
R5(config)#router eigrp 1
R5(config-router)#no auto-summary
R5(config-router)#network 10.0.0.0
R6(config)#router eigrp 1
R6(config-router)#no auto-summary
R6(config-router)#network 172.16.0.0
Using the examples above and the network diagrams, finish configuring EIGRP on all of the routers.
Confirmation: To verify routing, there are a number of commands at your disposal. Over time, you will learn many ways to diagnose and troubleshoot routing problems. Start off with the show ip protocols command.

At the end of each lab, you will need to verify that everything is working. To do this, you will need to ping from each device to every IP address in your network. This is not practical to do by hand, so we will use a handy tool called TCL (Pronounced tickle) scripts.
The basic syntax for this command is
tclsh
foreach address {
<address 1>
<address 2>
<address 3>
<…>
} {
ping $address
}
tclquit
R1#tclsh
R1(tcl)#foreach address {

For any ping that fails, go back and recheck the previous sections of the lab. Do the best you can to troubleshoot. If you cannot figure it out, call over a TA to give you a hand.
Once you have verified that the script works on every device, submit it to WebCT to be graded.
