Name:
1. Distance vector routing protocols are like using _______________ to guide you
on your way to a destination, only giving you information about distance and
direction. However, link-state routing protocols are like using a _________.
2. Link-state routing protocols are also known as ___________________ protocols.
3. Name, define, and describe the algorithm that link-state protocols are built
around:
4. What are the two most commonly encountered link-state routing protocols in IP
networks?
5. The shortest path is not necessarily the path with the least number of
__________, instead, Link-State Routing Protocols base their routing decisions
on a metric of ________________________.
6. List the five steps in reaching convergence with the link-state routing process:

7. With link-state routing protocols, a link is:
8. The link must be in the ______ state before the link-state routing protocol can
learn about a link, and the interface must be included in one of the
______________________________ before it can participate in the link-state
routing process.
9. What is included in the information about the state of a link (the Link-State)?

10. Routers with link-state routing protocols use a _________________ to discover
any neighbors on its links. A neighbor is any other router that is enabled with the
same ______________________________________________________.
11. How does a link-state routing protocol discover if it has any neighbors?
12. When two link-state routers learn that they are neighbors, they form an
____________________________.
13. What happens if a Link-State router stops receiving hello packets from a
neighbor?
14. What is an LSP and what information does it contain?
15. What does a router do when it receives an LSP from a neighboring router and
what is this process called?

than distance vector protocols?
17. Are LSPs sent periodically? If not, when are they sent?
18. What is the Link-State Database?
19. List and describe the advantages of link-state routing protocols compared to
distance vector routing protocols:
20. What is the advantage of multiple areas within a routing domain?
