Selecting Network Devices
When designing a network, it is important to select the proper hardware to meet current network requirements and to allow for network growth. Within an enterprise network, both switches and routers play a critical role in network communication.
Selecting Switch Hardware
Match the business consideration on the left with the switch feature on the right. This is a one-to-one matching exercise.

Managing Devices
A basic router or switch configuration includes the hostname for identification, passwords for security, and assignment of IP addresses to interfaces for connectivity. A router configuration also includes basic routing.
In addition to configuration commands, router and switch verification commands are used to verify the operational status of the router or switch and related network functionality. Use the address scheme in Table 1-2 in the following exercises that review the most common router and switch configuration and verification commands.

Basic Router Configuration Review
Using Table 1-2 and the following requirements, record the commands, including the router prompt, to implement a basic router configuration:
- Hostname is R1.
- Console and Telnet line’s password is cisco.
- Privileged EXEC password is class.
- Banner message-of-the-day.
- Interface addressing.
- OSPF routing, including an appropriate router ID.
- Save the configuration.
