372 1587133032_CCNP_ROUTE_Student.indb 5 10/20/10 2:26 PM CCNP ROUTE Lab Manual vi About This Lab Manual This is the only authorized Lab Manual for the Cisco Networking Academy CCNP version 6 ROUTE course A CCNP certification equips students with the knowledge and skills needed to plan, implement, secure, maintain, and troubleshoot converged enterprise networks. The CCNP certification requires candidates to pass three 120-minute exams—ROUTE #642-902, SWITCH #642-813, and TSHOOT #642-832—that validate the key competencies of network engineers. The Cisco Networking Academy curriculum consists of three experience-oriented courses that employ industry-relevant instructional approaches to prepare students for professional-level jobs: CCNP ROUTE: Implementing IP Routing, CCNP SWITCH: Implementing IP Switching, and CCNP TSHOOT: Maintaining and Troubleshooting IP Networks. CCNP ROUTE: Implementing IP Routing This course teaches students how to implement, monitor, and maintain routing services in an enterprise network. Students will learn how to plan, configure, and verify the implementation of complex enterprise LAN and WAN routing solutions, using a range of routing protocols in IPv4 and IPv6 environments. The course also covers the configuration of secure routing solutions to support branch offices and mobile workers. The 32 comprehensive labs in this manual emphasize hands-on learning and practice to reinforce configuration skills. Command Syntax Conventions The conventions used to present command syntax in this book are the same conventions used in the IOS Command Reference. The Command Reference describes these conventions as follows: • Boldface indicates commands and keywords that are entered literally as shown. In actual configuration examples and output (not general command syntax), boldface indicates commands that are manually input by the user (such as a show command). • Italic indicates arguments for which you supply actual values. • Vertical bars (|) separate alternative, mutually exclusive elements. • Square brackets ([ ]) indicate an optional element. • Braces ({ }) indicate a required choice. • Braces within brackets ([{ }]) indicate a required choice within an optional element. 1587133032_CCNP_ROUTE_Student.indb 6 10/20/10 2:26 PM CCNP ROUTE Lab Manual 1 Chapter 1 Routing Services Lab 1-1, Tcl Script Reference and Demonstration Instructor Version Topology Objectives • Use Tcl scripts to verify full connectivity. • Identify causes of failures. Background The Cisco IOS Scripting feature provides the ability to run Tool Command Language (Tcl) commands from the Cisco IOS command-line interface (CLI). Tcl scripts can be created to accomplish routine and repetitive functions with Cisco IOS-based networking devices. In this lab, you create and execute a Tcl script that sends pings to multiple IP addresses in the network to test overall network connectivity. Note: Cisco IOS Release 12.3(2)T and later supports Tcl scripting. Required Resources • 2 routers (Cisco 1841 with Cisco IOS Release 12.4(24)T1 Advanced IP Service or comparable) • Serial and console cables Note: This lab uses Cisco 1841 routers with Cisco IOS Release 12.4(24)T1 and the advanced IP image c1841-advipservicesk9-mz.124-24.T1.bin. Other routers (such as a 2801 or 2811) and Cisco IOS Software versions can be used if they have comparable capabilities and features. Depending on the router model and Cisco IOS Software version, the commands available and output produced might vary from what is shown in this lab. 1587133032_CCNP_ROUTE_Student.indb 1 10/20/10 2:26 PM CCNP ROUTE Lab Manual 2 Step 1: Congure initial settings. Copy and paste the following initial congurations for R1 and R2. Router R1 hostname R1 ! interface loopback 1 ip address 10.1.1.1 255.255.255.252 ! interface loopback 2 ip address 10.1.2.1 255.255.255.252 ! interface loopback 3 ip address 10.1.3.1 255.255.255.252 ! interface loopback 4 ip address 10.1.4.1 255.255.255.252 ! interface serial 0/0/0 ip address 10.100.12.1 255.255.255.252 clock rate 64000 bandwidth 64 no shutdown ! router rip version 2 network 10.0.0.0 no auto-summary ! end Note: A 30-bit subnet mask (255.255.255.252) is used for the serial links in this lab. However, starting with IOS 12.2(4)T, the 31-bit subnet mask (255.255.255.254) is supported on IPv4 point-to-point interfaces (per RFC 3021), requiring only 2 IP addresses per point-to-point link (.0 and .1). The IP Unnumbered feature can also be used to conserve IP addresses. Router R2 hostname R2 ! interface loopback 1 ip address 10.2.1.1 255.255.255.252 ! interface loopback 2 ip address 10.2.2.1 255.255.255.252 ! interface loopback 3 ip address 10.2.3.1 255.255.255.252 ! interface loopback 4 ip address 10.2.4.1 255.255.255.252 1587133032_CCNP_ROUTE_Student.indb 2 10/20/10 2:26 PM CCNP ROUTE Lab Manual 3 ! interface serial 0/0/0 bandwidth 64 no shutdown ! router rip version 2 network 10.0.0.0 no auto-summary ! end Do you think that these congurations will achieve full connectivity between R1 and R2? Explain. _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ None of the pings across the serial link will succeed because the serial 0/0/0 interface on R2 does not have an IP address. R1 will not be able to ping any addresses on R2, and R2 will not be able to ping any addresses on R1. R1 is also unable to ping its 10.100.12.1 address on its serial 0/0/0 interface because that ping must travel rst to R2 before returning to R1. This will be explained in more detail later in the lab. Step 2: Verify connectivity. The simplest way to verify OSI Layer 3 connectivity between two routers is to use ICMP. ICMP denes a number of message types in RFC 792 for IPv4 and RFC 4443 for IPv6. (See www.ietf.org and http://tools.ietf.org for more information.) ICMP denes procedures for echo (ping), traceroute, and source notication of unreachable networks. Pinging an IP address can result in a variety of ICMP messages, but the only message indicating that a ping is successful is the ICMP echo reply message indicated by an exclamation point (!) in the output of the ping command. The following command on R1 pings its Lo1 interface. Loopback interfaces always have a status of UP/UP. R1# ping 10.1.1.1 Type escape sequence to abort. Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds: !!!!! Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms In Step 1, you might have noticed that the R2 conguration omits an IP address on serial 0/0/0. R2 does not exchange IP packets with R1 because the IP protocol is not running on the R2 serial interface until the IP address has been congured. 1587133032_CCNP_ROUTE_Student.indb 3 10/20/10 2:26 PM CCNP ROUTE Lab Manual 4 Without this IP address, for which addresses in the topology diagram do you expect the ping to fail? _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ _________________________________________________________________________________ None of the pings across the serial link will succeed because the serial 0/0/0 interface on R2 does not have an IP address. R1 will not be able to ping any addresses on R2, and R2 will not be able to ping any addresses on R1. R1 is also unable to ping its 10.100.12.1 address on its serial 0/0/0 interface because that ping must travel rst to R2 before returning to R1. This will be explained in more detail later in the lab. Step 3: Create and execute a Tcl script. Tcl scripts can be created to accomplish routine and repetitive functions with Cisco IOS-based networking devices. To construct a simple connectivity verication script, do the following. a. Open a text editor and create a new text le. Using a text le saves time, especially if you are pasting the Tcl script into multiple devices. b. Start with the tclsh command to enter Tcl shell mode in which you can use native Tcl instructions like foreach or issue EXEC mode commands. You can also access conguration mode from within the Tcl shell and issue conguration commands from their respective menus, although these features are not explored in this lab. R1# tclsh R1(tcl)# c. Begin a loop using the foreach instruction. The loop iterates over a sequence of values, executing a dened sequence of instructions once for each value. Think of it as “for each value in Values, do each instruction in Instructions.” For each iteration of the loop, $identier reects the current value in Values. The foreach instruction uses the following model. foreach identier { value1 value2 . . . valueX } { instruction1 instruction2 . . . instructionY } d. To create a Tcl script that pings every IP address in the topology, enter each IP address in the value list. Issue the ping $address command as the only instruction in the instruction list. 1587133032_CCNP_ROUTE_Student.indb 4 10/20/10 2:26 PM [...]... online 1587133032 _CCNP_ ROUTE_ Student.indb 21 10/20/10 2:26 PM 22 CCNP ROUTE Lab Manual Verify the neighbor relationships and that the routing table of each router has the original loopback interfaces of the other routers, as described in the initial diagram Make sure that you issue the debug ip eigrp command on all routers a Issue the show ip route command on R2 and R3 R2# show ip route eigrp 10.0.0.0/24... to trigger the route recalculation on each router Therefore, RIPv2 would drop more packets during reconvergence than EIGRP 1587133032 _CCNP_ ROUTE_ Student.indb 24 10/20/10 2:26 PM CCNP ROUTE Lab Manual 25 Router Interface Summary Table Router Model 1700 1800 2600 2800 Ethernet Interface #1 Fast Ethernet 0 (FA0) Fast Ethernet 0/0 (FA0/0) Fast Ethernet 0/0 (FA0/0) Fast Ethernet 0/0 (FA0/0) Router Interface... adjacent You get output similar to the following R3# debug ip eigrp 100 IP-EIGRP Route Events debugging is on R3# conf t Enter configuration commands, one per line 1587133032 _CCNP_ ROUTE_ Student.indb 29 End with CNTL/Z 10/20/10 2:26 PM 30 CCNP ROUTE Lab Manual R3(config)# router eigrp 100 R3(config-router)# network 10.0.0.0 R3(config-router)# *Feb 4 18:44:57.367: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 100: Neighbor... by the loopback interfaces on each of the three routers The physical devices have just been installed and are connected by Fast Ethernet and serial interfaces Your task is to configure EIGRP to enable full connectivity between all departments 1587133032 _CCNP_ ROUTE_ Student.indb 13 10/20/10 2:26 PM 14 CCNP ROUTE Lab Manual Note: This lab uses Cisco 1841 routers with Cisco IOS Release 12.4(24)T1 and the...
