 ![Lab 1](img/day-08-ipv4.png)
+
+1. **Configure R1's Hostname**
+
+   * Access R1's CLI (Command Line Interface).
+   * Enter privileged EXEC mode: `enable`
+   * Enter global configuration mode: `configure terminal`
+   * Set the hostname to R1: `hostname R1`
+
+2. **Configure IP Addresses on R1's Interfaces**
+
+   * **Interface G0/0:**
+     * Enter interface configuration mode: `interface GigabitEthernet 0/0`
+     * Assign IP address 15.0.0.1 with subnet mask 255.0.0.0: `ip address 15.0.0.1 255.0.0.0`
+     * Enable the interface: `no shutdown`
+     * Set interface description: `description Connection to SW1`
+     * Exit interface configuration mode: `exit`
+
+   * **Interface G0/1:**
+     * Enter interface configuration mode: `interface GigabitEthernet 0/1`
+     * Assign IP address 182.98.0.1 with subnet mask 255.255.0.0: `ip address 182.98.0.1 255.255.0.0`
+     * Enable the interface: `no shutdown`
+     * Set interface description: `description Connection to SW2`
+     * Exit interface configuration mode: `exit`
+
+   * **Interface G0/2:**
+     * Enter interface configuration mode: `interface GigabitEthernet 0/2`
+     * Assign IP address 201.191.20.1 with subnet mask 255.255.255.0: `ip address 201.191.20.1 255.255.255.0`
+     * Enable the interface: `no shutdown`
+     * Set interface description: `description Connection to SW3`
+     * Exit interface configuration mode: `exit`
+
+3. **Verify R1's Configuration**
+
+   * View interface status and configuration: `show ip interface brief`
+
+   [Include a screenshot of the output of `show ip interface brief` here.]
+
+4. **Configure IP Addresses on PCs**
+
+   * **PC1:**
+     * Open PC1's Desktop tab.
+     * Click on "IP Configuration".
+     * Assign IP address 15.0.0.10 with subnet mask 255.0.0.0.
+     * Set Default Gateway to 15.0.0.1.
+
+   * **PC2:**
+     * Open PC2's Desktop tab.
+     * Click on "IP Configuration".
+     * Assign IP address 182.98.0.10 with subnet mask 255.255.0.0.
+     * Set Default Gateway to 182.98.0.1.
+
+   * **PC3:**
+     * Open PC3's Desktop tab.
+     * Click on "IP Configuration".
+     * Assign IP address 201.191.20.10 with subnet mask 255.255.255.0.
+     * Set Default Gateway to 201.191.20.1.
+
+5. **Test Connectivity**
+
+   * **From PC1:**
+     * Open PC1's Command Prompt.
+     * Ping PC2: `ping 182.98.0.10`
+     * Ping PC3: `ping 201.191.20.10`
+
+   [Include screenshots of successful ping results from PC1 to PC2 and PC3.]
+
+**Troubleshooting**
+
+* If you encounter issues with pinging between devices, double-check the IP address and subnet mask configurations on the router and PCs.
+* Ensure that all interfaces are enabled (`no shutdown`).
+* Use the `show ip route` command on the router to verify that routes are properly installed.
