There are several methods available for configuring Cisco routers. It can be done over the network from a TFTP server. It can be done through the menu interface provided at bootup, and it can be done from the menu interface provided by using the command setup. This tutorial does not cover these methods. It covers configuration from the IOS command-line interface only.more

The purpose of this document is to demonstrate a basic configuration of Intermediate System-to-Intermediate System (IS-IS) for IP on Cisco routers. In addition to the configuration, we demonstrate how to monitor various IS-IS information, such as Designated Intermediate System (DIS) election information and IS-IS database information. ..more

This is a simple guide on how to set up your Cisco DSL router for DHCP using PPPoE. The examples in this chapter also show how to configure NAT so you can also have a home / SOHO based website. This page should be suitable for the following Cisco routers: more

Configuring your CISCO router

Before powering on your router you will need to:

· Configure a terminal emulator program (HyperTerminal, etc..) on your PC for 9600 baud, 8 data bits, no parity and 1 bit stop
· Determine the network protocol to be used (IP, IPX, AppleTalk)
· Which WAN protocol will be used (Frame Relay, HDLC, X.25, etc, etc….)
· Connect the serial connector the your PC and the other end to the console port on the router

Power on your router, wait for the stop scrolling through the screen. You will then be prompted by the following message:

Would you like to enter the initial configuration dialog? [yes/no]: no
(if you answer no, you will be prompted to terminate the Auto Install and configure the router manually.)

The first set of instructions are for configuring a hostname, a password and an IP address on the local Ethernet interface.

At the prompt issue the following commands:

· Router> enable
· Configure terminal
· Router (config) # hostname whoever (this is used to setup a hostname for the router
· Whoever (config) # enable secret guessme (this is used to establish a password for entering to Privileged mode. Substitute the word guessme for you own password)
· Whoever (config)# Line console 0
· Whoever (config-line) # exec-timeout 0 0 (this will prevent your session from timing out)
· Whoever (config-line)# exit (to return to global configuration mode)
· Whoever# ip routing (to establish IP routing protocol) [NOTE: to enable Novell or Apple networks use the following commands, ipx routing or AppleTalk routing]
· Whoever# configure terminal
· Whoever (config) # interface Ethernet 0/0 (this will take you into the interface configuration mode where you can specify the IP address for the interface)
· Whoever(config) # ip address 172.16.1.1 255.255.255.0

The instructions below are for setting up a serial interface. This will start from privileged mode with the router name still being “Whoever”.

· Whoever # configure terminal
· Whoever (config) # ip routing
· Whoever (config) # interface serial 0/0
· Whoever (config-if) # ip address 172.16.8.1 255.255.255.0 (to assign the IP address to the serial interface)
· Whoever (config) # controller t1 0/0 (select the PRI interface to configure)
· Whoever (config-controller) # clock source line (specify which end of the circuit provides clocking. The clock source should be set to use internal clocking only for testing the network or if the full T1 line is used as the channel group. Only one end of the T1 line should be set to internal.)
· Whoever (config-controller) # framing esf (this is the framing type)
· Whoever (config-controller) # linecode b8zs (this is the line code format)
· Whoever (config-controller) # channel-group 0 timeslots 1, 3-5, 7 (this specifies the channel group and time slots to be mapped. For multiplex trunk interfaces, only channel 0 can be configured)
· Type exit, or hit Ctrl + Z (to return to privilege mode and save the configurations)
· copy running-config startup-config (to save the existing configuration over the default configuration)

After following the above instructions you will need to go into interface mode and bring the Ethernet and Serial interfaces online. The following will show you how to achieve this. (the router name is still “Whoever”)

While in privilege mode do the following:

· Whoever# configure terminal
· Whoever (config) # interface Ethernet 0/0
· Whoever (config-int) # no shutdown
· Whoever (config-int) # interface Serial 0/0
· Whoever (config-int) # no shutdown
· Type exit, or hit Ctrl + Z (to return to privilege mode and save the configurations)
· copy running-config startup-config (to save the existing configuration over the default configuration)

To configure your router for telnet access you will need to do the following:

· Whoever # configure terminal (to go into global configuration mode)
· Whoever (config) # line vty 0 4 (this allows the maximum amount of connections)
· Whoever (config-line) # login
· Whoever (config-line) # password guessme (this is the password that will need to be used when someone telnets into the system. REPLACE THE WORD quessme WITH YOUR OWN PASSWORD)
