Cisco Router Configuration Tutorial :

Getting started with Cisco :
Router>
2.1 Modes :
Router>?
2.2 Unprivileged and privileged modes :
Router>show ?
Router>
to
Router#

3. Configuring your Cisco Router :

Router#show interfaces
Router#show ip protocols
Router#show ip route
Router#show ip arp

3.1 Global configuration (config) :

Router#config terminal
Router(config)#
Router(config)#hostname ExampleName
ExampleName(config)#

Another useful command issued from config
mode is the command to designate the DNS server to be used by the router:

ExampleName(config)#ip name-server aa.bb.cc.dd
ExampleName(config)#ctrl-Z
ExampleName#

This is also where you set the password for privileged mode :

ExampleName(config)#enable secret examplepassword
ExampleName(config)#ctrl-Z
ExampleName#

3.2 Configuring Cisco router interfaces
Cisco interface naming is straightforward.Individual interfaces are referred to by this convention:

media type slot#/port#
ExampleName#show interface ethernet 6/2
If your router does not have slots, like a 1600, then the interface name consists only of:

media type port#
For example:

ExampleName#show interface serial 0
Here is an example of configuring a serial port with an IP address:

ExampleName#config
ExampleName(config)#interface serial 1/1
ExampleName(config-if)#ip address 192.168.155.2 255.255.255.0
ExampleName(config-if)#no shutdown
ExampleName(config-if)#ctrl-Z
ExampleName#
ExampleName#show interface serial 1/1

ExampleName(config)#interface serial 1/1
ExampleName(config-if)#shutdown
ExampleName(config-if)#ctrl-Z
ExampleName#show interface serial 1/1
ExampleName(config)#interface serail 1/1
ExampleName(config-if)#no ip address 192.168.155.2 255.255.255.0
ExampleName(config-if)ctrl-Z
ExampleName#show interface serial 1/1

3.3 Configuring Cisco Routing

ExampleName(config)#ip routing
ExampleName(config)#ctrl-Z

There are two main ways a router knows where to send packets. The administrator can assign static routes, or the router can learn routes by employing a dynamic routing protocol :

ExampleName#config
ExampleName(config)#ip route 172.16.0.0 255.255.255.0 192.168.150.1
ExampleName(config)#ctrl-Z
ExampleName#show ip route

This document describes how to configure the Routing Information Protocol (RIP)on Cisco routers. From the command-line, we must explicitly tell the router which protocol to use, and what networks the protocol will route for:

ExampleName#config

ExampleName(config)#router rip
ExampleName(config-router)#network aa.bb.cc.dd
ExampleName(config-router)#network ee.ff.gg.hh
ExampleName(config-router)#ctrl-Z
ExampleName#show ip protocols

3.4 Saving your Cisco Router configuration :

ExampleName#show running-config
ExampleName#show startup-config

3.5 Example Cisco Router configuration :

Router>enable

Router#config
Router(config)#hostname Pelatihan
Pelatihan(config)#interface serial 1/1
Pelatihan(config-if)ip address 192.168.155.2 255.255.255.0
Pelatihan(config-if)no shutdown
Pelatihan(config-if)ctrl-z
Pelatihan#show interface serial 1/1
Pelatihan#config
Pelatihan(config)#interface ethernet 2/3
Pelatihan(config-if)#ip address 192.168.150.90 255.255.255.0
Pelatihan(config-if)#no shutdown
Pelatihan(config-if)#ctrl-z
Pelatihan#show interface ethernet 2/3
Pelatihan#config
Pelatihan(config)#router rip
Pelatihan(config-router)#network 192.168.155.0
Pelatihan(config-router)#network 192.168.150.0
Pelatihan(config-router)#ctrl-z
Pelatihan#show ip protocols
Pelatihan#ping 192.168.150.1
Pelatihan#config
Pelatihan(config)#ip name-server 172.16.0.10
Pelatihan(config)#ctrl-z
Pelatihan#ping archie.au
Pelatihan#config
Pelatihan(config)#enable secret password
Pelatihan(config)#ctrl-z
Pelatihan#copy running-config startup-config
Pelatihan#exit

4. Troubleshooting your Cisco router :

ExampleName#show interfaces
ExampleName#show ip protocols
ExampleName#show ip route
ExampleName#show ip arp

4.1 Testing connectivity :

IP Message Control Protocol (ICMP)

ExampleName#ping xx.xx.xx.xx
ExampleName#trace xx.xx.xx.xx
