Chapter 1 Lab 1-1, Tcl Script Reference and Demonstration InstructorVersion
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. Inthis 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 1841routers 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.

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 10.1.2.1255.255.255.252
!
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 address10.2.2.1 255.255.255.252
!
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

Do you think that these configurations 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...
