BASIC ROUTER CONFIGURATION

Copyright (c) 1998-2004 Boson Software, Inc. All Rights Reserved. LAB 1 – BASIC ROUTER CONFIGURATION 1. In this lab, you will get practice with basic configuration and show commands on the Cisco router. 2. Select Router1 from the tool bar. Press enter to get to the user prompt Router> 3. 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> ? 4. Type enable to get into privileged mode. The pound sign (#) indicates you are now in privileged mode. Router> enable Router# 5. 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# ? 6. Exit privileged mode by typing disable. Router# disable Router> 7. Re-enter privileged mode and type configure terminal to get into configuration mode Router> enable Router# configure terminal Router(config)# 8. Configure a hostname of ‘router1’ (without the quote marks). Notice how the prompt changes. Router(config)# hostname router1 router1(config)# 9. 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 6 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<tab> 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 3 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? If not, what commands should you use for trouble- shooting? router2# ping 160.10.1.1 Copyright (c) 1998-2004 Boson Software, Inc. All Rights Reserved. LAB 2 – ADVANCED ROUTER CONFIGURATION 1. In this lab you will practice using some advanced configuration and show commands on the Cisco router. Please remember your lab 1 commands needed to switch between Router modes (i.e. exit, end, disable) 2. On router1, configure a console password of ‘boson’. The console user must enter this password before gaining access to the user mode prompt. router1(config)# line console 0 router1(config-line)# login router1(config-line)# password boson 3. Configure a banner that says” Welcome to Router1 - Authorized Users Only”. router1(config)# banner motd # Welcome to Router1 - Authorized Users Only # 4. Test the banner and console password by logging out of the router and logging back in. Get into enable mode after successfully logging into the console. router1# logout enter password: boson router1> enable password: cisco router1# 5. Configure a password of ‘cisco’ on router2 that will enable remote users to Telnet into it: router2(config)# line vty 0 4 router2(config-line)# login router2(config-line)# password cisco 6. On router1, associate a name of ‘router2’ with the remote IP address 160.10.1.2. This will allow you to ping router2’s name rather than having to remember its IP address. router1(config)# ip host router2 160.10.1.2 7. Verify that the name is in router1’s host table with the show hosts command. router1# show hosts 8. Ping ‘router2’ and verify that the pings succeed. router1# ping router2 Copyright (c) 1998-2004 Boson Software, Inc. All Rights Reserved. 9. Display the contents of flash memory on router2. a. Question: what is the name of the IOS image in flash and how large is it? router2# show flash 10. Display the history table on router1. This shows the last 10 commands that were entered on the router. You can recall commands by entering CTRL-P or by hitting the up arrow key. router1# show history router1# ctrl-p (to see previously entered commands) 11. On router1, do a show interfaces on Serial 0. Note on the third line of the output that the bandwidth is assumed to be 1544kb. This is because the router assumes all serial links are T1’s unless you configure otherwise. Configure router1’s S0 link to have a bandwidth of 64kb and then reenter the show interfaces command. router1# show interfaces serial 0 router1# configure terminal router1(config)# interface serial 0 router1(config-if)# bandwidth 64 router1(config-if)# clock rate 64000 router1(config-if)# ctrl-z router1# show interfaces serial 0 12. On router1, add a description to interface Serial 0 that says “Serial Link to Router3”. This description will appear whenever you issue a show interfaces command for Serial 0. router1(config)# interface serial 0 router1(config-if)# description Serial Link to Router3 router1(config-if)# exit router1(config)# exit router1# show interfaces serial 0 13. Configure router3 and router4: • configure hostnames • configure an enable secret password of ‘cisco’ • assign IP addresses and subnet masks to serial & Ethernet interfaces (see table on page 6) • Remember to set the clock rate on the Router 3 Serial 1 interface. • activate serial and Ethernet interfaces • verify router3 can ping router1 • verify router3 can ping router4 • save the configurations to NVRAM Copyright (c) 1998-2004 Boson Software, Inc. All Rights Reserved. LAB 3 - CDP 1. In this lab, you will practice using Cisco Discovery Protocol (CDP) commands to view information about directly connected neighbors. 2. On router1, display summary information for router1’s CDP neighbors. You should see one-line entries for both router2 and router3. router1# sh cdp neighbors 3. On router1, display detailed information about CDP neighbors. You can do this with either the show cdp neighbors detail or show cdp entry * commands. router1# show cdp neighbors detail router1# show cdp entry * 4. On router1, display the interfaces where CDP is active. a. Question: what is the CDP advertisement interval? b. Question: what is the holdtime interval and what does it signify? router1# show cdp interface 5. On router1, change the CDP advertisement interval to 50 sec. and the holdtime interval to 170 sec. Issue the show cdp interface command to verify the new timers are set correctly. router1(config)# cdp timer 50 router1(config)# cdp holdtime 170 router1(config)# exit router1# sh cdp interface Copyright (c) 1998-2004 Boson Software, Inc. All Rights Reserved. LAB 4 – TELNET 1. In this lab, you will practice Telnet’ing from one router to another. You will suspend Telnet sessions using the ctrl-shift-6 X sequence and display active Telnet sessions using the show sessions and show users commands. 2. From router1, Telnet to router2 (160.10.1.2). Once into router2, issue the show users command. This command shows which remote users are Telnet’ed into this local router. You should see router1’s IP address (160.10.1.1) as the user Telnet’ed into router2. router1# telnet 160.10.1.2 router2> router2# show users 3. Suspend your Telnet session to router2 by pressing CTRL-SHIFT-6 and X. You should return to router1 without breaking the active Telnet session. Issue the show sessions command on router1. This command shows what active, but suspended, sessions you have to other routers. router2# ctrl-shift-6 x router1# router1# show sessions 4. Now Telnet from router1 to router3. Suspend the session and return to router1. Issue the show sessions command. You should now see two suspended sessions: one to router2 (160.10.1.2) and one to router3 (175.10.1.2). router1# telnet 175.10.1.2 router3> router3> ctrl-shift-6 x router1# router1# show sessions 5. Disconnect the two suspended sessions on router1. The number used in the disconnect command comes from the left-most column in the show sessions output. Issue show sessions to see if the suspended Telnet sessions have disappeared. router1# disconnect 2 router1# disconnect 1 router1# show sessions Copyright (c) 1998-2004 Boson Software, Inc. All Rights Reserved. LAB 5 - TFTP 1. In this lab, you are going to configure PC1 as a TFTP-Server. You will then backup and restore router4’s configuration to the TFTP-Server. 2. Under the NetSim, select PC1 from the Other Devices drop-down menu. Configure PC1 to have an IP address of 195.10.1.2 with a mask of 255.255.255.0 and a default- gateway of 195.10.1.1. Use the winipcfg utility on the PC to do this. The PC is automatically enabled to be a TFTP server. c:> winipcfg 3. On router4, make sure you can ping PC1: router4# ping 195.10.1.2 4. On router4, copy your running-configuration to the tftp-server. You will be prompted for the address of the tftp-server (195.10.1.2). You will also be prompted for a file name (any name you choose). router4# copy running-config tftp 5. On the tftp-server (PC1), issue the show tftp-configs command to see if router4’s configuration was successfully backed up (this is not a standard PC command, but one developed for use with the NetSim). c:> show tftp-configs 6. You will now restore the configuration you saved on the TFTP server to NVRAM on router4. Make sure router4’s NVRAM is currently empty by issuing the show startup- config command. If it is not empty, use the erase startup-config command to clear it. Restore the configuration from the tftp-server to NVRAM on router4 with the following copy command (enter the PC’s IP address and previously-saved file name when prompted): router4# copy tftp startup-config 7. Issue the show startup-config command. You should now see the restored configuration file in NVRAM. a. Question: was it necessary to clear out router4’s NVRAM in order to copy a file into it? Why? Copyright (c) 1998-2004 Boson Software, Inc. All Rights Reserved. LAB 6 - RIP 1. In this lab, you will be configuring RIP. On router1, router2, router3, and router4, configure RIP V1 on all serial and Ethernet interfaces (except for the ISDN and frame relay interfaces). a. Question: On router1, why doesn’t the network statement under RIP specify 160.10.1.0 rather than 160.10.0.0? router1(config)# router rip router1(config-router)# network 160.10.0.0 router1(config-router)# network 175.10.0.0 router2(config)# router rip router2(config-router)# network 160.10.0.0 router3(config)# router rip router3(config-router)# network 175.10.0.0 router3(config-router)# network 180.10.0.0 router3(config-router)# network 197.10.1.0 router4(config)# router rip router4(config-router)# network 180.10.0.0 router4(config-router)# network 195.10.1.0 2. On router1, issue the show ip protocols command. This commands shows information about all dynamic routing protocols that are running on the router. Based on the output of this command: a. Question: how frequently does RIP advertise routing updates? b. Question: what is the holddown timer interval for RIP? router1# show ip protocols 3. On router4, issue the show ip route command. You should see two directly connected routes (180.10.1.0 and 195.10.1.0) and three remote routes (160.10.0.0, 197.10.1.0 and 175.10.0.0). a. What is the administrative distance for RIP? router4# show ip route 4. On router4, ping both router1 and router2. The pings should succeed if RIP is configured on all routers. router4# ping 175.10.1.1 router4# ping 160.10.1.2 [...]... and router4 Use AS# 200 router1 (config)# router igrp 200 router1 (config -router) # network 160.10.0.0 router1 (config -router) # network 175.10.0.0 router2 (config)# router igrp 200 router2 (config -router) # network 160.10.0.0 router3 (config)# router igrp 200 router3 (config -router) # network 175.10.0.0 router3 (config -router) # network 180.10.0.0 router3 (config -router) # network 197.10.1.0 router4 (config)# router. .. interfaces router1 (config)# router eigrp 100 router1 (config -router) # network 160.10.0.0 router1 (config -router) # network 175.10.0.0 router2 (config)# router eigrp 100 router2 (config -router) # network 160.10.0.0 router3 (config)# router eigrp 100 router3 (config -router) # network 175.10.0.0 router3 (config -router) # network 180.10.0.0 router3 (config -router) # network 197.10.1.0 router4 (config)# router eigrp 100 router4 (config -router) #... ospf 1 router2 (config -router) # network 160.10.1.0 0.0.0.255 area 0 router3 (config)# router ospf 1 router3 (config -router) # network 175.10.1.0 0.0.0.255 area 0 router3 (config -router) # network 180.10.1.0 0.0.0.255 area 0 router3 (config -router) # network 197.10.1.0 0.0.0.255 area 0 router4 (config)# router ospf 1 router4 (config -router) # network 180.10.1.0 0.0.0.255 area 0 router4 (config -router) # network 195.10.1.0... routerx(config)# no router eigrp 100 2 Configure OSPF on router1 , router2 , router3 , and router4 Use Process ID 1 and configure OSPF to send and receive updates on all interfaces excluding the ISDN and Frame Relay interfaces router1 (config)# router ospf 1 router1 (config -router) # network 160.10.1.0 0.0.0.255 area 0 router1 (config -router) # network 175.10.1.0 0.0.0.255 area 0 router2 (config)# router ospf 1 router2 (config -router) #...
