CCNPv6 ROUTE

Chapter 1 Lab 1-1, Tcl Script Reference and Demonstration
TopologyObjectives
• • 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 Tclscript 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 theadvanced 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.

CCNPv6 ROUTE

Step 1: Configure initial settings.
Copy and paste the following initial configurations 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) issupported 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 ! interface serial 0/0/0 bandwidth 64

Step 2: Verify connectivity.
The simplest way to verify OSI Layer 3 connectivity between two routers is to use ICMP. ICMP defines 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...
