    # Your First Cisco Lab — CLI Basics


    A free, ungraded starter lab from Goldfish Networks. There is nothing to
    grade here — the goal is simply to get comfortable moving around the Cisco
    IOS command line and to bring a link up for the first time.


    ## Topology


    - **R1** — a router that boots almost blank. You will give it a hostname and
    bring up its Ethernet0/0 interface.

    - **PC1** — a host, already set to 192.168.1.10/24 with its default gateway
    at 192.168.1.1. You do not need to touch PC1.


    R1 Ethernet0/0 connects to PC1. Your job is to configure R1's Ethernet0/0 as
    192.168.1.1/24, bring it up, and ping PC1.


    ## What you'll practice


    - Moving between user EXEC (`>`), privileged EXEC (`#`), and global config
    (`(config)#`)

    - `show` commands: `show ip interface brief`, `show version`,
    `show running-config`

    - Setting a hostname, configuring an interface, and `no shutdown`

    - Verifying with a ping, then saving your work
