Study Notes

Configuring Host Addressing

Configure host PCs with IPv4 and IPv6 addressing values from the Addressing Table.
Configure the Server with addressing values from the Addressing Table.

Configuring the Router

Configure the router with initial configurations learned in the course.
Connect a console cable to the router via console and connect it to a host via RS 232.
Use the following commands:
- enable
- configure terminal
- hostname (e.g., CS-Department)
- enable secret (e.g., cisco12345)
- line console 0 and line vty 0 4 with password and login configuration
- security passwords minimum length 10
- service-password encryption
- username netadmin secret Cisco_CCNA7
- ip domain-name cisco.com and crypto key generate rsa with 1024-bit encryption key strength
- ip ssh version 2 and line vty 0 4 with login local and transport input ssh

Configuring Gigabit Ethernet Interfaces

Configure two Gigabit Ethernet interfaces using IPv4 and IPv6 addressing values.
Reconfigure link local addresses according to the Addressing Table.
Document interfaces in the configuration file using:
- interface g0/0 and interface g0/1 with IP and IPv6 addresses, subnet masks, and descriptions.
