Dynamic Routing Protocols (RIP and OSPF) What you will learn in this lab: How the dynamic routing protocol Routing Information Protocol (RIP) exchanges messages. How RIP reconfigures the routing tables after a change in the network topology. How the link state routing protocol Open Shortest Path First (OSPF) works. Convergence problems in RIP without split-horizon and triggered updates. Copyright 2001, Jörg Liebeherr. All Rights Reserved. Lab 5

ITL LAB 5 - PAGE 3 SPRING 2001 Prelab 5 1. Refresh your knowledge of link state and distance vector routing protocols. Review the count- to-infinity problem and the split-horizon heuristic in distance vector routing protocols. What are the key differences between distance vector routing algorithms and link state algorithms? 2. Review Lab 3 to find answers to the following questions: 2.1. On a Redhat 6.2 system, which files contain the information on the IP addresses of the system? 2.2. On a Redhat 6.2 system, which file contains the information if the system is an IP router? 2.3. Which lines do you need to set in the file given in 2.2 to setup a Linux PC, such that it performs IP forwarding (i.e., acts as an IP router) ? 3. What are the key differences between distance vector routing algorithms and link state 4. Go to the website of gated at http://www.gated.org/gated-web/code/doc/manuals/quickstart/whatisgated.html and read about gated . Also read how to configure gated to run RIP, at http://www.gated.org/gated-web/code/doc/manuals/config_guide/samp_host.html . 4.1. What are the different routing protocols supported by gated? 4.2. Explain the statement “running RIP in passive mode”. You can find information at http://www.gated.org/gated-web/code/doc/manuals/config_guide/rip_stmt.html . 4.3. Provide the configuration file, which forces gated to run RIP in passive mode on a specific network interface. (Hint: Check the sample configuration file at http://www.gated.org/gated-web/code/doc/manuals/config_guide/samp_host.html) 5. Read the manpage of gdc at http://www.gated.org/gated-web/code/doc/manuals/operation_guide/gdc.html. The gdc program is used to start, stop, and reconfigure the gated daemon. 5.1. Provide the syntax of gdc for checking whether gated is running. 5.2. Provide the syntax of gdc for forcing gated to reread its configuration file. 6. Read the manpage of ospf_monitor at http://www.gated.org/gated-web/code/doc/manuals/operation_guide/ospf_monitor.html. 6.1. Provide the syntax of an entry in the mon_db_file, which queries the OSPF routing daemon on the machine vintpc1 with IP address 10.0.10.1. 6.2. How does one save all the output from ospf_monitor into a file?
