Scenario
Configuration is half the job; reading state is the other half. A router can be misconfigured, perfectly configured but cabled wrong, or perfectly configured and cabled right but waiting on a peer. show commands are how you tell which. In this lab, R1 is pre-loaded with a small config: hostname, description, IP address, loopback. Nothing is broken. Just read.
