What are the steps to configure a router?

Pre-requisite: Cisco Router basic commands. Show Routing is the method of selecting a network packet path over the Internet or between or through multiple networks. Routing is conducted on many kinds of networks, including circuit-switched networks, such as public switched telephone networks (PSTN), and computer networks, such as the Internet. In this article, we will see configure the router in Cisco Packet Tracer. Steps to Configure the Router:Step 1. Open the packet tracer desktop and take a Router (2911) and PC0 from the devices. 
Step 2: Configure the Host name of the router0.
router> router>en router#conf t router(config)#hostname r1 r1(config)exit Step 3: Set a message of the day (MOTD) banner for the users. r1(config)#banner motd $ then, enter MOTD and end it with ‘$’ to exit. r1(config)#banner motd $ Enter TEXT message. End with the character '$'. Unauthorised access is stricltly prohibited $ Step 4: setting up line control password and enable secret password To configure the Line Control password and Enable secret follow the below commands: r1#conf t r1(config)# r1(config)#line con 0 r1(config-line)#password GFG123 r1(config-line)#login r1(config-line)#exit r1(config-line)#enable password cisco r1(config)#enable secret GFG@123 r1(config)#service password-encryption sh(config)#exit Step 5: Verifying password
To save the configuration use the below command: r1#copy run startup-config How to Setup Basic Cisco Router Configuration Step-By-Step?Many of us will be having a Cisco-based routers at home or at an organization. And many of us sometimes struggle with basic router configuration steps and a wrong configuration can be deadly. Therefore, this post will help you with all the basic Cisco router network configurations in a step-by-step way, so that your Cisco routers are safe and efficient. In this post, we will be specifically focusing on configuring your Cisco routers using "Command Line Interface" (CLI). There are certain complex configuration tasks that can easily be done via CLI and hence mastering CLI for your Cisco routers is essential and important. Some of the important CLI configuration/command modes are listed below:
There are also other configuration/command modes based on VLAN such as:
A short overview of all the modes with their entry and exit methods for Cisco router configuration management:
How to connect to a Router in order to Configure it?There are two ways through which you can connect to your router
For the first time, that is the device is not yet configured, You can connect directly with console cable via CON port. This type of connection is known as "out-of-band connection". Once the router is configured accordingly, you can connect remotely by using Telnet or SSH. This type of connection is known as "in-band connection". SSH is preferred over Telnet because of its encrypted traffic. Cisco Router Configuration Step by Step Commands Step 1: Create local accounts and set password for accessing modes The first and the most important step in configuring your Cisco router is security. The best way to provide top security is by adding passwords.You can secure your access to the Cisco router with this way. You can also add passwords for Telnet or Console if needed. A. Steps to configure local account with username and password: To add a level of security to the Cisco router, you can create local user accounts with usernames and passwords. This feature works by asking for a username and password set by the user immediately after providing IP in putty before entering Command Line Interface (CLI). Use the following commands to create local accounts: 1. Enter Privileged EXEC Mode and type the following commands:
CiscoRouter(config)# username networksupervisor46 privilege 15 secret $NonHackable270746$ CiscoRouter(config)# username superiorsupervisor93 privilege 1 secret @safepass!9346$$ 2. After creating the above local accounts, you then apply the “local” authentication type to the lines:
CiscoRouter(config-line)# login local CiscoRouter(config-line)# exit CiscoRouter(config)# line console 0 CiscoRouter(config)# line aux 0 3. To save and write these accounts use the following command:
Only when we configure line commands with local login, password will be prompted while logging in to the CiscoRouter. B. Steps to set password for Privileged EXEC Mode entry: To set an additional level of security, that is, after entering CLI and for accessing different modes, you can add password to enter Privileged EXEC Mode from User EXEC Mode. 1. Change your configuration mode to Global Configuration Mode as given below:
CiscoRouter(config)# Here, in Global Configuration Mode, configured parameters affect the whole device. 2. To enable or add a password, use the "enable secret" command:
3. To be on a more safer side, it is advised to have passwords for Telnet also, which will provide you with safer access to Telnet lines over the network:
CiscoRouter(config-line)# password "Telnetnetworkpass" CiscoRouter(config-line)# login Step 2: Add a Router Hostname Hostname is what differentiates your router from other routers or devices in a network. To change or configure a new hostname follow the below commands:
Router7997(config)# Step 3: Configure IP addresses for Router Interfaces IP addresses or internet protocol addresses are the most important and most basic interface for any network devices. This particular step is the most important as it helps your device forward packets. To perform this step, you need to change mode from Global Configuration Mode to Interface Configuration Mode. Use the following commands to configure IP address to your Cisco router:
Router7997(config-if)# ip address 192.168.0.0 255.255.255.252 Router7997(config-if)# no shutdown Router7997(config-if)# exit Router7997(config)# interface GigabitEthernet 0/1 Step 4: Configure Routing One of the primary functions of a router is to forward packets to the best possible route in the destination network. There are two ways that a router follows to send packets in the network:
Dynamic routing Static routing: Static routing performs routing decisions with preconfigured routes in the routing table, which can be changed manually only by administrators. Static routes are normally implemented in those situations where the choices in route selection are limited, or there is only a single default route available. Also, static routing can be used if you have only a few devices for route configuration and there is no need for route change in the future. Dynamic routing: Dynamic routing continuously updates its routing table with paths and their cost/metric, while making optimal routing decisions based on changing network operating environments. Static routing is considered the simplest form of routing and it is predominately preferred or used for simple network topologies. You can configure static routing from Global Configuration Mode as follows:
Router7997(config)# ip route 200.200.200.0 255.255.255.0 100.100.100.2 The command above contains three parts as destination network, subnet mask, and gateway. It conveys that the network 200.200.200.0 is reachable via the gateway 100.100.100.2. The subnet mask for this is given as 255.255.255.0. There is also a default static route as follows:
There is no specific gateway address here and the router sends all packets to the ISP gateway by default. Step 5: Save your configuration Configuration are vital to a network and it must be saved or secured in the best way. Once a configuration is saved, you can also view it anytime or else use that configuration anytime you want. It helps especially during downtime. You can save the configurations to NVRAM. Once you save the current configuration, it will overwrite the startup configurations. Save your configurations in the following way:
Router7997# copy running-config startup-config To display your saved current configuration, follow this command:
Step 6 (optional): Configure NAT This step is considered as optional as it is required only if your router acts as an internet gateway. Click here to know more information about "Configuring dynamic NAT in Cisco devices". Step 7 (optional): Configure DHCP This is also an optional step, which is used to assign IP address dynamically to internal hosts. Here, Cisco router is configured as a DHCP server. Click here to know more information about "Configure DHCP server on Cisco devices". What is the first step in configuring a router?The first step is to setup Wi-Fi access on your Laptop/PC using the Wi-Fi details (SSID and password). Now you should be able to connect to the router, and the router should assign you an IP address. You can check your IP address and find the IP address of the router by using the ipconfig command.
