Question 1

What is dynamic routing?

Answer 1

Routers communicating with each other about known networks

Question 2

How are rules of communication and information exchanged defined?

Answer 2

via routing protocols

Question 3

What type type of algorithm do routing protocols implement?

Answer 3

a modified SPP algorithm (shortest path problem)

Question 4

What are the major characteristics of routing protocols? (4)

Answer 4

1) Single-path or multi-path
2) Interior or exterior to an autonomous system
