Question

What are the basic router configuration steps that are similar to switch configuration?

Answer

The initial "housekeeping" tasks — name the device, lock down management access (passwords, banner), and save — are identical on a router and a switch because both run Cisco IOS.

A router and a Layer 2 switch share the same IOS command-line, so when you first bring up either one you perform the same set of foundational tasks before doing anything device-specific (interfaces on a router, VLANs on a switch). Knowing this means the security baseline you already learned on switches transfers directly to routers.

Step	Command	Why it matters
1. Configure device name	`hostname name`	Makes the prompt identify the device, avoiding mistakes when several are open
2. Secure privileged EXEC	`enable secret password`	Protects the powerful privileged mode; `secret` is hashed, unlike `enable password`
3. Secure user EXEC	`line console 0` → `password pwd` → `login`	Stops walk-up console access
4. Secure remote access	`line vty 0 4` → `password pwd` → `login` → `transport input ssh telnet`	Protects the virtual terminal lines used for Telnet/SSH
5. Encrypt passwords	`service password-encryption`	Hides remaining plaintext passwords in the config file
6. Legal notification	`banner motd #message#`	Displays a legal warning to anyone connecting
7. Save configuration	`copy running-config startup-config`	Copies the live (RAM) config to NVRAM so it survives a reboot

Key insight: These steps secure management access and are device-agnostic. What differs is what comes next — on a router you then configure routed interfaces (each needs no shutdown and its own IP), which a Layer 2 switch does not have.

Cisco IOS (Wikipedia) — the shared IOS command-line that makes these housekeeping steps identical across device types.
