4.4 Summary of Session 4

In this session you’ve looked at routing. You have practised configuring different devices with IP addresses and seen how routers use these to get data across networks.

New terms

In this session you have met the following terms.

default route

The route a packet takes when no specific route is defined in the routing table. In a home network all packets from a device on the network will be sent to the default gateway via the default route.

hop

One section of the path (from one network device to the next) taken by a packet between the source and destination.

metric

A value that refers to how efficient a route that a packet can take is. It can be used by routers to determine the most efficient routes and make routing decisions.

netstat –r

A command (short for network statistics) that can be used to view the routing table for a system.

RIP

Stands for Routing Information Protocol and is one type of routing protocol that is used by routers to exchange information about other networks.

route print

A command that can be used to view the routing table for a system.

routing table

Contains data about various routes to other networks that a router uses to determine how to direct or route packets.

routing protocol

A set of rules that uses software and algorithms to specify how routers share information with each other.
