Q&A

Q. Why are there many routing protocols, but only two major routing algorithms?

A. The algorithms that are in use today are very efficient. The protocols, however, might decide to implement those algorithms in slightly different ways. By this, one protocol might decide to pass the algorithm different metrics than another protocol. Thus, even though many protocols use the same algorithm, each one uses it in a different way.

Q. What are the two major types of routing algorithms?

A. Distance vector and link-state.

Q. What are metrics?

A. Values collected by routing protocols that are passed to algorithms. They are used to calculate the routing paths.

Q. Which type of routing algorithm maintains the smallest routing table?

A. Link-state.

Q. What will a link state protocol do when the state of one of its links changes?

A. Initiate a routing update.
