| Lab 12.1.5 Static routes Estimated time: 30 min. Objectives: Configure a static route between direct neighboring routers using the ip route command. Copy the running configuration to startup configuration. Background: In this lab you will configure a static route between neighboring routers. Static routes are routes that cause packets moving between a source and a destination to take a specified path. They are typically defined manually by a network administrator. Routing updates are not sent on a link if it is only defined by a static route, thereby conserving bandwidth. Another application for a static route is security since dynamic routing tends to reveal everything known about a network. Static routes are sometimes used for remote sites and for testing of a particular link or series of routers in your internetwork. Tools / Preparation: Prior to starting this lab you will need to connect a PC workstation (with the HyperTerminal program loaded) to a router using the router's console interface with a roll-over (console) cable. All lab work is done through the HyperTerminal program that is configured to connect to the router. You may want to review Chapter 18 in the Cisco Networking Academy First-Year Companion Guide and review semester 2 online curriculum Chapter 12 prior to starting this lab. Work individually or in teams. Be familiar with the following command: Enable Show arp Show startup-config Configure terminal IP route Show running-config copy Ping Resources Required: PC with monitor, keyboard, mouse, power cords, etc. Windows operating system (Win 95, 98, NT or 2000) installed on PC HyperTerminal program configured for router console connection PC connected to the router console port with a roll-over cable Websites Sites Required: Routing basics General information on routers 2500 series routers 1600 series routers Terms and acronyms IP routing protocol IOS command summary Notes: Step 1 – Login to router. Explanation: Connect to the router and login. Enter the password cisco if prompted. Step 2 – Test layer 3 (network) connectivity. Task: Enter ping xxx.xxx.xxx.xxx Explanation: xxx.xxx.xxx.xxx is an IP address of your one of your neighboring routers. 1. Did the router’s interface respond with a successful ping? Step 3 – Enter privileged mode. Task: a. Enter enable at the command prompt. b. Enter the password of class. Explanation: You use the enable command to enter privileged EXEC mode. Step 4 – Show the backup configuration file. Task: Enter show startup-config (abbrev. show start) at the router prompt. Explanation: The router will display information on the backup configuration file stored in NVRAM. 2. What routing protocols or static routes are defined, if any? Step 5 – Enter global configuration mode. Task: Enter configure terminal (abbrev. config t) at the router prompt. Explanation: To configure the router you must enter the global configuration mode. Notice how the router prompt has change after this command. 3. What does the router prompt look like? Step 6 – Enter help facility. Task: Enter IP route ? command at the router prompt. Explanation: The router will respond with the description available for IP route. 4. What was the router’s response? Step 7 – Enter the help facility. Task: Enter IP route xxx.xxx.xxx.xxx ? at the router prompt. Explanation: xxx.xxx.xxx.xxx is the network address for which you want a static route. 5. What was the router's response? Step 8 - Enter the help facility. Task: Enter IP route xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy at the router prompt. Explanation: xxx.xxx.xxx.xxx. is the network address of the destination network and yyy.yyy.yyy.yyy is the subnet mask of the destination network. 6. What was the router's response? Step 9 - Enter a static route. Task: Enter IP route xxx.xxx.xxx.xxx yyy.yyy.yyy.yyy zzz.zzz.zzz.zzz at the router prompt. Explanation: xxx.xxx.xxx.xxx. is the network address of the destination network and yyy.yyy.yyy.yyy is the subnet mask of the destination network. zzz.zzz.zzz.zzz is the IP address of the direct neighbor interface. Step 10 - Exit the router global configuration mode. Task: Enter exit at the router prompt. Explanation: The router will exit the global configuration mode. 7. What does the router prompt look like? Step 11 - Show the running configuration. Task: Enter show running-config at the router prompt. Explanation: The router will show the active configuration file. 8. Was there an IP route with the static route you configured in the active configuration file? Step 12 - Copy the active configuration to the backup configuration. Task: Enter copy running-config startup-config at the router prompt. Explanation: This command will permanently write the configuration change to memory. Step 13 - Test the static route with the ping command. Task: Enter ping xxx.xxx.xxx.xxx at the router prompt. Explanation: xxx.xxx.xxx.xxx. is the neighboring router to which you setup a static route. 9. Was the neighboring router interface reachable? Step 14 - Exit the router.
