| Lab 12.3.5 Rip routing Estimated time: 45 min. Objectives: Configure RIP as your Routing Protocol Background: In this lab you will configure RIP as the routing protocol. RIP is a distance-vector routing protocol. Hop count is used as the metric for path selection and has a maximum allowable hop count of 15. RIP broadcasts routing updates consisting of its routing table to its neighbors every 30 seconds by default. RIP is a standard protocol which is appropriate for relatively small homogeneous networks. Tools / Preparation: Prior to starting the lab the teacher will have to login to each router and delete all router RIP and static route entries from all of the routers. 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 1 on-line chapter 12 prior to starting this lab. Work individually or in teams. Be familiar with the following commands: Enable Show IP route Show startup-config Configure terminal Network Show running-config Copy Show IP protocols Router RIP 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 the router. Explanation: Connect to the router and login. Enter the password cisco if prompted. Step 2 - Test layer 3 connectivity. Task: Enter ping xxx.xxx.xxx.xxx Explanation: Ping all interfaces on your router and direct neighboring routers. 1. Did all interfaces respond with a successful ping? Step 3 - View the routing table. Task: Enter show IP route at the router prompt. Explanation: The router will respond with its routing table. 2. Is there any routing protocol defined? Step 4 - 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 5 - Show information about the active configuration file. Task: Enter show running-config at the router prompt. Explanation: The router will display information on the active configuration file. 3. Are there any static routes defined? Step 6 - Enter global configuration mode. Task: Enter configure terminal at the router prompt. Explanation: To configure the router you must enter the global configuration mode. Notice how the router prompt has changed after this command. 4. What does the router prompt look like? Step 7 - Enable RIP as your routing protocol. Task: Enter router RIP command at the router prompt. Explanation: This will enable RIP on the router. 5. What changed in the router prompt? Step 8 - Enable RIP routing on a particular IP network. Task: Enter network xxx.xxx.xxx.xxx at the router prompt. Explanation: xxx.xxx.xxx.xxx is the network address on which you want to enable RIP on. Step 9 - Enable RIP routing on a particular IP network. Task: Repeat step 8 for all the networks directly connected to the router. Step 10 - Exit router configuration mode. Task: Enter exit at the router prompt. Explanation: The router will exit out of router configuration mode and you will be in global configuration mode. Step 11 - Exit the router global configuration mode. Task: Enter exit at the router prompt. Explanation: The router will exit the global configuration mode. Step 12 - Show the running configuration. Task: Enter show running-config at the router prompt. Explanation: The router will show the active configuration file. 6. Is the router RIP protocol turned on and advertising the networks you defined? Step 13 - 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. 7. What does this command do? Step 14 - View the IP protocols. Task: Enter show IP protocols at the router prompt. Explanation: The router will display values about routing timers and network information associated with the entire router. 8. When is the next update due? Step 15 - View the routing table. Task: Enter show IP route at the router prompt. Explanation: The router will display its routing table. 9. How many routes were discovered by RIP? Step 16 - Display the status and global parameters. Task: Enter show IP interface at the router prompt. Explanation: The router displays the status and global parameters associated with an interface. 10. What information did you receive from this command? Step 17 - Display RIP routing updates as they are sent and received. Task: Enter debug IP RIP at the command prompt. Explanation: This command allows you to display RIP routing updates as they are sent and received. 11.What important information did you received from this command? Step 18 - Turn off debug for RIP. Task: Enter no debug IP RIP at the router prompt. Explanation: This command will turn off the debugging for RIP. Step 19 - Exit the router.
