NETSIM FOR CCNA LAB MANUALSequential Labs

Sequential LabsThe CCNA® labs contained in this lab guide are based on the Boson NetSim. This Windows®-based product simulates a wide variety of Cisco routers as well as the Cisco Catalyst 1900, 2950, and 5000 switches. The NetSim supports multiple routing protocols, including RIP, IGRP, EIGRP, and single-area OSPF. It supports differ-ent LAN/WAN protocols, including PPP/CHAP, ISDN, and Frame Relay. The exercises in this lab guide require only the NetSim – they do not require access to any external router or switch hardware. It should be noted that the NetSim supports many, but not all, of the IOS commands available on a real router or switch. All the commands referenced in this lab guide are supported through the Simulator.

Lab TopologyThe Lab Topology is shown in the diagram on the next page. (It can also be viewed by selecting the NetMap but-ton at the top of the NetSim screen.) You will have access to the following devices:

Four Cisco 2500 routersEach router has one Ethernet interface and two serial interfaces. One of the Cisco 2500 routers, Router 1, has an ISDN BRI interface.

This router has one Ethernet interface. This router has both an ISDN BRI and a PRI interface.

Two Catalyst 1912 switchesEach of these switches has twelve 10baseT and two Fast Ethernet ports.

Two Catalyst 2950 switchesEach of these switches has twelve 10/100 Ethernet ports.

Lab 3: CDPObjective: In this lab, you will practice using Cisco Discovery Protocol (CDP) commands to view information about directly connected neighbors.

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 On router1, display detailed information about CDP neighbors. You can do this with either the show cdp neighbors detail command or the show cdp entry * command.router1# show cdp neighbors detailrouter1# show cdp entry *On router1, display the interfaces where CDP is active. router1# show cdp interface

3a. Question: What is the CDP advertisement interval? 3b. Question: What is the default hold-down interval? What does the hold-down interval signify?

On router1, change the CDP advertisement interval to 50 seconds and the hold-down interval to 170 seconds. Issue the show cdp interface command to verify that the new timers are set correctly.router1(config)# cdp timer 50router1(config)# cdp holdtime 170router1(config)# exitrouter1# sh cdp interface

Lab 4: TelnetObjective: In this lab, you will practice telneting from one router to another. You will use the CTRL+SHIFT+6 X key combination to suspend Telnet sessions and use the show sessions and show users commands to display active Telnet sessions.

Make sure you have permitted Telnet access on router3.router3# config trouter3(config)# line vty 0 4router3(config-line)# loginrouter3(config-line)# password ciscoFrom router1, telnet to router2 (160.10.1.2). Once into router2, issue the show users command. This command shows which remote users are telneted into this local router. You should see router1’s IP ad-dress (160.10.1.1) as the user that telneted into router2.router1# telnet 160.10.1.2router2>router2> show usersSuspend your Telnet session to router2 by pressing CTRL+SHIFT+6 X. You should return to router1 with-out breaking the active Telnet session. Issue the show sessions command on router1. This command shows what active, but suspended, sessions exist with other routers.router2# CTRL+SHIFT+6 Xrouter1#router1# show sessionsNow, telnet from router1 to router3. Suspend the session, and return to router1. Issue the show sessionscommand. You should now see two suspended sessions: one to router2 (160.10.1.2) and one to router3

Lab 14: IP Access ListsObjectiveserial 0 interface.

Ensure that you can ping router2 (160.10.1.2) from both router3 and router4. The path to router2 is through router1’s serial 0 interface. If you cannot successfully ping router2, ensure that IP addresses have been assigned, all interfaces are up, and that a dynamic routing protocol (RIP, IGRP, EIGRP, or OSPF) is running on all routers.router3# ping 160.10.1.2

router4# ping 160.10.1.2

2a. Question: Is a deny any statement required in the access list?2b. Question: What does the subnet mask 0.0.0.255 mean in the access list?2c. Question: Can any number be assigned to a standard IP access list?

Test your access list by pinging from router3 and router4 to router2. The pings from router3 (in subnet 175.10.1.0) should succeed, whereas the pings from router4 (in subnet 180.10.1.0) should fail.

Appendix A: Answers to Questions8a. The enable secret (encrypted) password is used, and the enable password is ignored.17a. No. Nothing will be saved to NVRAM until you issue the copy running-config startup-config command.20a. 12.1(9)T20b. 0x210221a. IP is the only protocol currently running on the router. IP is supported by default on the Cisco router.

Routing for other Layer 3 protocols must be turned on explicitly using commands such as ipx routing or decnet routing.

25a. Both the status and the protocol should be up.25b. The status would be administratively down.26a. If you cannot successfully ping router1, you should use one of the following commands on router1:

show interfaces (to verify that the interfaces are up)show run (to verify that the IP addresses and subnet masks are correct)

Lab 3 – CDP3a. CDP advertises information every 60 seconds by default.3b. The default hold-down interval is 180 seconds. This is how long the remote device should keep this

CDP advertisement information in its tables if it does not receive another CDP advertisement from this device.

Lab 5 – TFTP

already stored in DRAM.Lab 6 - RIP

1a. The network statements under both RIP and IGRP must specify classful network numbers (Class A, B, or C addresses), not subnet addresses. The 160.10.1.0 address is a subnet address, not a classful ad-dress.

2a. every 30 seconds2b. 180 seconds3a. 120

Lab 7 – IGRP3a. every 90 seconds

3b. 280 seconds3c. 100 (maximum of 100 routers along the path)4a. 1006a. The debug ip igrp events command traces IGRP routing updates without showing individual network

numbers. The debug ip igrp transactions command shows routing updates with individual network numbers that are being advertised or received.

Lab 8 – EIGRP3a. 100 hops6a. The EIGRP topology database contains primary and backup routes to each destination learned from

EIGRP neighbors. The best routes (those with the lowest composite metric) are termed successor routes and are inserted in the IP routing table on the router.

7a. 90Lab 9 – OSPF

3a. OSPF is a link state routing protocol and does not send out periodic routing updates.

5a. The default cost is 10, which is calculated by dividing the speed of the interface into 100,000,000. The default cost can be overridden using the ip ospf cost interface-level command.

7a. It is in the forwarding state.7b. The duplex setting for interface e0/2 is half-duplex. 10baseT ports default to half-duplex.9a. Version V4.00.009b. 00-0C-55-09-32-1110a. 000C.1835.856510b. 10010c. 20 seconds10d. 2 seconds

Lab 11 – VLANs and Trunking (Catalyst 1900 Switches)4a. The Catalyst 1900 switch defaults to server mode.5a. No. Although VLAN 10 has been created, no ports have been manually assigned to it yet.

Lab 13 – VLANs and Trunking (Catalyst 2950 Switches)5a. No. Although VLAN 20 has been created, no ports have been manually assigned to it yet.

8a. 802.1QLab 14 – IP Access Lists

2a. No. An implicit deny any statement is at the end of every access list.2b. This is a wildcard or reverse mask. It means permit any device where the source address starts with

2c. No. Standard IP access lists are in the range 1-99 or 1300-1999.4a. You can specify host 172.16.1.1 or 172.16.1.1 0.0.0.0.4b. 100-199 or 2000-26994c. access list 100 permit udp any any eq 520 (RIP uses UDP port 520)

Lab 15 – NAT/PAT4a. The inside global IP address normally represents a public, or registered, IP address. NAT/PAT translates

the inside local IP address, which is usually a private IP address, to an inside global IP address, which is usually a registered IP address.

Lab 17 – ISDN BRI-BRI using Legacy DDR3a. Both B channels are down and the line protocols are down because no calls are active.4a. The dialer-list and dialer-group5a. It should show 1 Active Layer 3 Call.6a. Now that a call has been established, one of the B channels should be up and the line protocol should

be up. The other B channel should still have a status of down and down.

1a. In Europe, the controller type is E1, the framing is either crc4 or no-crc4, and the linecode is hdb3.1b. The number 23 represents the ISDN signaling channel on the PRI/T1 link. It is the 24th time slot on the

T1 link.Lab 20 – Frame Relay
