Before configuring advanced routing protocols, it is important to understand the basic Cisco IOS router configuration commands.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this guide, we will learn <strong>Cisco router basic configuration step by step<\/strong>, including hostname configuration, enable secret, disabling DNS lookup, interface configuration, static routing, dynamic routing, RIP, EIGRP, and useful verification commands.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p class=\"wp-block-paragraph\"><strong>Note:<\/strong> The examples in this article are for learning and lab purposes. Always adapt interface names, IP addresses, passwords, and routing configuration to your actual network.<\/p>\n<\/blockquote>\n\n\n\n<h2 class=\"wp-block-heading\">Cisco Router Basic Configuration<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A newly initialized Cisco router has some default configuration. You can inspect the current configuration using:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Router# show running-config\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Cisco&#8217;s documentation shows that interfaces may initially have no IP address and may be administratively shut down.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">1. Enter Privileged EXEC Mode<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">First, enter privileged EXEC mode:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Router&gt; enable\nRouter#\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">The <code>enable<\/code> command gives access to privileged router commands.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">2. Enter Global Configuration Mode<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Use:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Router# configure terminal\nRouter(config)#\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">You can also use the shorter form:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Router# conf t\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Global configuration mode is where you configure the router&#8217;s hostname, passwords, interfaces, routing protocols, and other settings.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">3. Configure the Router Hostname<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A hostname makes it easier to identify the router.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Router(config)# hostname R1\nR1(config)#\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">The prompt changes from <code>Router<\/code> to <code>R1<\/code>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can use meaningful names such as:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>R1\nCORE-R1\nBRANCH-R1\nHQ-ROUTER\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Cisco documents the <code>hostname<\/code> command as the method for specifying the router&#8217;s name.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">4. Configure an Enable Secret Password<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Use:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>R1(config)# enable secret Cisco@123\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">The <code>enable secret<\/code> command protects privileged EXEC mode with a password. Cisco&#8217;s documentation describes it as an encrypted password used to help prevent unauthorized access to the router.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a real production network, use a strong, unique secret rather than the example above.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">5. Disable DNS Lookup<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">When you accidentally type an incorrect command, a Cisco router may try to interpret the word as a hostname.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To disable this behavior:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>R1(config)# no ip domain-lookup\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">This is especially useful in labs because it prevents the router from waiting while attempting DNS resolution. Cisco includes this command in its basic global-parameter configuration.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Configuring a Cisco Router Interface<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">One of the most important router configuration tasks is assigning an IP address to an interface.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, suppose we have:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Router R1\nInterface: GigabitEthernet0\/0\nIP Address: 192.168.1.1\nSubnet Mask: 255.255.255.0\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Enter:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>R1(config)# interface gigabitethernet 0\/0\nR1(config-if)# ip address 192.168.1.1 255.255.255.0\nR1(config-if)# no shutdown\nR1(config-if)# exit\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Cisco&#8217;s documented basic procedure for a Gigabit Ethernet interface is to enter the interface, configure the IP address and mask, issue <code>no shutdown<\/code>, and exit interface configuration mode.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What does <code>no shutdown<\/code> do?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Cisco interfaces can be administratively shut down.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The command:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>no shutdown\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">enables the interface.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You may see a message similar to:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>%LINK-5-CHANGED: Interface GigabitEthernet0\/0, changed state to up\n<\/code><\/pre>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Verify the Interface<\/h1>\n\n\n\n<p class=\"wp-block-paragraph\">After configuring the interface, use:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>R1# show ip interface brief\n<\/code><\/pre>\n\n\n\n<p class=\"wp-block-paragraph\">Example:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>Interface              IP-Address      OK?

class=\"wp-block-paragraph\">Cisco&#8217;s guide documents the RIP configuration sequence as entering RIP configuration mode, selecting the RIP version, specifying networks, optionally disabling automatic summarization, and exiting configuration mode.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h1 class=\"wp-block-heading\">Verify RIP<\/h1>\n\n\n\n<p
