            Requirement                                                                       Commands

Set a console password to cisco                               Router(config)#line con 0
                                                                              Router(config-line)#login
                                                                              Router(config-line)#password cisco

Set a telnet password                                              Router(config)#line vty 0 4
                                                                              Router(config-line)#login                                                                               Router(config-line)#password cisco

Stop console timing out                                          Router(config)#line con 0
                                                                            Router(config-line)#exec-timeout 0 0

Set the enable password to cisco                           Router(config)#enable password cisco 

Set the enable secret password to peter.                 Router(config)#enable secret peter

 This password overrides the enable password
and is encypted within the config file

Enable an interface                                                       Router(config-if)#no shutdown

To disable an interface                                                   Router(config-if)#shutdown

Set the clock rate for a router with a DCE cable to 64K    Router(config-if)#clock rate 
                                                                                   64000

Set a logical bandwidth assignment of 64K to the serial interface    
                                                                                 Router(config-if)#bandwidth 64
                                                                                 Note that the zeroes are not 
                                                                                 missing

To add an IP address to a interface                   Router(config-if)#ip addr 10.1.1.1/24

To enable RIP on all 172.16.x.y interfaces          Router(config)#router rip
                                                                     Router(config-router)#network 172.16.0.0

Disable RIP                                                     Router(config)#no router rip

To enable IRGP with a AS of 200, to all interfaces Router(config)#router igrp 200
                                                              Router(config-router)#network 172.16.0.0

Disable IGRP                                                    Router(config)#no router igrp 200

Static route the remote network is 172.16.1.0, with

a mask of 255.255.255.0, the next hop is 172.16.2.1,

at a cost of 5 hops                                 Router(config)#ip route 172.16.1.0

                                                                              255.255.255.0 172.16.2.1 5            

Disable CDP for the whole router                                  Router(config)#no cdp run

Enable CDP for he whole router                                    Router(config)#cdp run

Disable CDP on an interface                                        Router(config-if)#no cdp enable
