Configuring an IP Address on a Router

Router configuration

Now, let’s configure an IP address on a Cisco router. A router interconnects multiple networks through ports. For this course, a port is a physical place where a cable can be plugged. The name that we assign to the logical part of a port is an interface.

So, to sum things up:

• Port = Physical
• Interface = Logical

We’ll set an IP (logical) address on an interface and connect the cable (physically) to a port.

These interfaces must have an IP address configured to communicate within the network, and the interface must be turned on.
