Packet Tracer Single Router Lab - devinziegler/Devin-Tech-Journal GitHub Wiki

Assignment: Packet Tracer - Single Router Lab

Objective: Review the role of routers in networking and configure a simple routed network.

Goals:

Gain more experience with switching and routing technology and Packet Tracer.
Extend the switched network from the previous lab (3-4) to include 2 switches, and a router.

Router Commands:

Navigation:

enable

Logs you into enable mode, which is also known as privileged mode.

configure terminal

Logs you into configuration mode

interface <interface_name>

Enters the interface config mode for the specified interface

Save a config:

copy running-config startup-config

Saves active config to the startup config

copy startup-config running-config

Merges startup config with currently active config

Always make sure to save any progress before shutting off the device. After configuring a switch with multiple VLAN's, the last thing you want is to shut off without saving just because you forgot to add more ports at the beginning.

Editing Interfaces:

ip address <ip_address> <subnet_mask>

Assigns an IP address and subnet mask to selected interface.

ip default-gateway <ip_address_for_default_gateway>

Sets the default gateway.

Toggling interface:

shutdown

Shuts down interface.

no shutdown

Turns the interface on.
