Name:
1. Every router uses a ____________________ to make decisions where to send
packets. The ___________________ contains a set of routes, where each route
describes which gateway or interface the router needs to use to reach a specified
network.
2. A route has four main components:
a. _______________________
b. _______________________
c. _______________________
d. _______________________
3. Describe each of these four types of routes:
a. Directly-Connected Routes
b. Static Routes
c. Dynamically-Updated Routes (Dynamic Routes)
d. Default Route
4. Routing tables ________ contain end-to-end information about the entire path
from a ____________ network to a _______________ network. They only
contain information about the _________________________ along that path.
The _______________ is always a directly-connected gateway on
____________________________________.

5. Explain why larger networks generally use dynamic routing rather than static
routes:
6. Do Packet Tracer activity 6.1.1 “Configuring Static Routes”
7. What do routers use routing protocols to accomplish?
8. The method that a routing protocol uses to determine the best route to a
destination network is called a _________________________________.
9. What are the two main classes of routing algorithms?
10. Whenever the topology of a network changes because of reconfiguration or
failure, the __________________________ in all the routers must also change
to reflect an accurate view of the new topology. When all the routers in a network
have updated their _____________ to reflect the new route, the routers are said
to have ___________________________.
11. In order for two routers to exchange routes, they must be using
__________________ and therefore ______________________________.
