NET 222: Introduction to Routers and Routing

Review for Fourth Test
 
  1. Is EIGRP classed as a Distance Vector or a Link State protocol? Which kind of updates does it use?

  2. What three protocol stacks does the text tell us that EIGRP supports?

  3. What are hello packets? How often are they sent by EIGRP routers?

  4. What are multicast transmissions? How does EIGRP use multicasting?

  5. What information is kept in an EIGRP Neighbor table?

  6. What information is kept in an EIGRP Topology table? What kind of route information is kept here as well as in the Routes table?

  7. What kind of information is kept in an EIGRP Routes table? What are the routes in this table called?

  8. By default, by what criteria are Successors chosen? What are the other two criteria that can be used?

  9. How many routes to a given network can an EIGRP router hold in its Routes table? What is the command to enable it to hold this many?

  10. The text offers an example of RIP choosing a worse route than EIGRP in the same network infrastructure. How could this happen?

  11. What command is used to take down an interface on an EIGRP router?

  12. What protocol do EIGRP routers use to transport data? Is it reliable? What protocol do EIGRP routers use to select and request updates on routes?

  13. What command should be used to view all the EIGRP routes known to a router? What command should be used to see only the EIGRP routes the router actually intends to use?

  14. Compare the hop count limits of RIP, EIGRP, and OSPF.

  15. Which family of router protocols does OSPF belong to?

  16. How are autonomous systems treated differently by OSPF, compared to how they are treated by EIGRP?

  17. What is an ASBR? How is it different from an ABR?

  18. What is a stub area? What is a transit area?

  19. How does OSPF choose one route as better than another? What is the formula it uses?

  20. What is a process ID for an OSPF router? What is the range of allowable values for process IDs?

  21. What are the two options for values for area numbers? About how many different areas could you have in an autonomous system?

  22. What is the Administrative Distance of an OSPF route?

  23. What kind of OSPF networks will not use Designated Routers?

  24. When you configure OSPF on a router, what is the command to set the process ID?

  25. What are the three arguments to a network command for OSPF?

  26. Why is the hierarchical structure of OSPF more desirable than the flat structure of RIP?
