Basic Router Configuration • Lab - Advanced Router Configuration • Lab - CDP • Lab - Telnet • Lab - TFTP • Lab - RIP • Lab - IGRP • Lab - EIGRP • Lab - OSPF • Lab 10 – Catalyst 1900 Switch Configuration • Lab 11 - VLANs & Trunking (Catalyst 1900) • Lab 12 - Catalyst 2950 Switch Configuration • Lab 13 - VLANs and Trunking (Catalyst 2950) • Lab 14 - IP Access Lists • Lab 15 - NAT/PAT • Lab 16 - PPP & CHAP • Lab 17 - ISDN BRI-BRI using Legacy DDR • Lab 18 - ISDN BRI-BRI using Dialer Profiles • Lab 19 - ISDN PRI using Dialer Profiles • Lab 20 - Frame Relay There is also an optional IPX lab contained in Appendix A of this lab guide These labs build upon each other so the best approach is to follow the labs sequentially You will also be asked questions at various points during the lab Answers to these questions are contained in Appendix B at the back of this lab guide Appendix C also contains the completed configurations for selected labs Saving/Restoring Configuration Files You can save your work and exit at any point First, make sure you have selected the appropriate router/switch/PC button at the top of the NetSim screen The next step is to press File -> Save Device Config from the top of the screen You will then be prompted for a file name Each individual device configuration must be saved separately At a minimum, you should plan to save all configurations each time you power off your PC To restore a configuration file, make sure you have pressed the appropriate router/switch/PC button The next step is to press File -> Load Device Config (Overwrite) at the top of the screen and to select the correct saved configuration file The configuration will then be loaded Note: this process can take 15-20 seconds to complete and you will see configuration commands flash across the screen Be patient! Copyright (c) 1998-2004 Boson Software, Inc All Rights Reserved LAB – BASIC ROUTER CONFIGURATION In this lab, you will get practice with basic configuration and show commands on the Cisco router Select Router1 from the tool bar Press enter to get to the user prompt Router> The greater-than symbol ( >) in the prompt indicates you are in user mode Type ? to see a list of commands that can be entered in user mode Router> ? Type enable to get into privileged mode The pound sign (#) indicates you are now in privileged mode Router> enable Router# Type ? to see a list of commands that can be entered in privileged mode Notice that there are more commands available in privileged mode than are available in user mode Configure and reload are two such commands that can only be issued in privileged mode Router# ? Exit privileged mode by typing disable Router# disable Router> Re-enter privileged mode and type configure terminal to get into configuration mode Router> enable Router# configure terminal Router(config)# Configure a hostname of ‘router1’ (without the quote marks) Notice how the prompt changes Router(config)# hostname router1 router1(config)# In global configuration mode on router1, type enable ? This will show valid parameters that can be entered with the enable command Configure an enable password of ‘ccnalab’ that will not be encrypted when viewing the Copyright (c) 1998-2004 Boson Software, Inc All Rights Reserved router configuration file and an enable password of ’cisco’ that will be encrypted a Question: when both encrypted and unencrypted enable passwords are configured, which one is used? router1(config)# enable ? router1(config)# enable password ccnalab router1(config)# enable secret cisco 10 Configure an IP address for the Ethernet0 interface on router1 (refer to the table on page for all IP addresses and masks) Activate the interface – it is currently in ‘shutdown’ mode You should see a message that the interface has now come up Practice using the tab key – type int and then the tab key (no spaces) You should see the word interface spelled out router1(config)# int router1(config)# interface ethernet0 router1(config-if)# ip address 160.10.1.1 255.255.255.0 router1(config-if)# no shutdown 11 Configure an IP address for router1’s Serial0 interface (refer to the table for IP addresses and masks) and activate the interface Practice using abbreviated commands for both interface serial0 and no shutdown router1(config-if)# int s0 router1(config-if)# ip address 175.10.1.1 255.255.255.0 router1(config-if)# no shut 12 Exit configuration mode by keying ctrl-z This will bring you back to the privileged mode prompt You could also accomplish the same thing by keying exit twice The exit command moves you back one level (from interface-configuration mode - global configuration mode - privileged mode prompt) router1(config-if)# ctrl-z router1# 13 Type logout to exit the command line interface router1# logout 14 Press the enter key to get back into the user mode prompt and then type enable to get into privileged mode You will be prompted for the enable secret password ‘cisco’ which you previously configured router1> enable password: cisco router1# Copyright (c) 1998-2004 Boson Software, Inc All Rights Reserved 15 Display a summary of all interfaces by typing: router1# show ip interface brief 16 Display detailed information on each interface by typing: router1# show interfaces 17 Display the active configuration in DRAM by typing: router1# show running-config 18 Display the saved configuration in NVRAM by typing show startup-config a Question: does anything exist in NVRAM? If not, why not? router1# show startup-config 19 Save the running (active) configuration to NVRAM by typing: router1# copy running-config startup-config 20 Now display the contents of NVRAM again This time, you should see the active configuration saved in NVRAM router1# show startup-config 21 Issue the show version command and answer these questions: a Question: What IOS release is running on router1? b Question: What are the contents of the configuration register? router1# show version 22 Issue the command to show which Layer protocols are currently running on the router a Question: which protocols are currently running on the router? router1# show protocols 23 Select router2 from the toolbar on top Press enter and get into user mode From there go into privileged mode Router> enable Router# configure terminal Router(config)# 24 Configure a hostname of ‘router2’ and configure an enable secret password of ‘cisco’ for router2 Copyright (c) 1998-2004 Boson Software, Inc All Rights Reserved Router(config)# hostname router2 router2(config)# enable secret cisco 25 Configure an IP address for Fast Ethernet 0/0 on router2 and activate the interface (see the diagram above for IP addresses and masks) Router2 is 2600 modular router and must be configured using slot/port notation router2(config)# interface Fa 0/0 router2(config-if)# ip address 160.10.1.2 255.255.255.0 router2(config-if)# no shut 26 Display the summary status of all interfaces Remember to get out of configuration mode first before issuing any show commands a Question: what status should interface Fa 0/0 show if it is fully activated? b Question: what status would Fa 0/0 show if it was in ‘shutdown’ mode? router2(config-if)# ctrl-z router2# show ip interface brief 27 Try to ping router1’s Ethernet address (160.10.1.1) from router2 a Question: Were you successful?
