    Study Notes

    Cisco Router Configuration Basics

    Learning Objectives

    • Learn how to login to a router and login options available
    • Understand modes of router configuration
    • Learn how to check links and router interfaces, protocols running
    • Verify routing table contents
    • Configure IP address and bring up router interfaces to running state
    • Configure login banner on routers

    Basic Components of Cisco Router

    • Interfaces
    • The Processor (CPU)
    • Internetwork Operating System (IOS)
    • RXBoot Image
    • RAM
    • NVRAM
    • ROM
    • Flash memory
    • Configuration Register

    Interfaces

    • Allow connection to a LAN
    • Examples: E0 (first Ethernet interface), E1 (second Ethernet interface), S0 (first Serial interface), S1 (second Serial interface), BRI 0 (first B channel for Basic ISDN), BRI 1 (second B channel for Basic ISDN)

    The Processor (CPU)

    • Main processor that takes care of main functions of the router
    • Generates interrupts (IRQ) to communicate with other electronic components
    • Uses RISC processors
    • CPU utilization on a normal router wouldn't exceed 20%

    The IOS

    • Main operating system on which the router runs
    • Loaded upon router's bootup
    • Size: 2-5MB, but can be larger depending on router series
    • Gives router its capabilities and can be updated or downloaded from the router for backup purposes
    • Available on a PCMCIA Flash card

    The RXBoot Image

    • Cut-down version of the IOS located in the router's ROM
    • Used for minor maintenance operations and bringing up/down interfaces when no Flash card is available

    The RAM

    • Where the router loads the IOS and configuration file
    • Works like a computer's memory, where the operating system loads along with programs
    • Amount of RAM needed depends on IOS image and configuration file size
    • Routing tables are stored in RAM, so larger and complex routing tables require more RAM

    The NVRAM

    • Special memory place where the router holds its configuration
    • Configuration is stored in NVRAM when saved
    • Not big compared to system's RAM
    • Not erased when the router is reloaded or switched off

    ROM

    • Used to start and maintain the router
    • Contains code like Bootstrap and POST for basic tests and bootup
    • Cannot be altered as it's set from the factory and is Read Only

    Flash Memory

    • An EEPROM card
    • Contains IOS image(s)
    • Can be written to or deleted from the router's console
    • Fits into a special slot at the back of the router

    Cisco Router Configuration Basics

    • A router is a device with its own specialized Operating System (OS), having RAM, permanent storage, processor, and interfaces or ports.
    • The purpose of configuring a router is to make it ready to use in networks for forwarding traffic.

    Basic Components of Cisco Router

    • Interfaces: allow connecting the router to a LAN, e.g., Ethernet ports or serial ports.
    • Processor (CPU): executes instructions and performs tasks.
    • Internetwork Operating System (IOS): the operating system of the router.
    • RXBoot Image: a boot image that loads the IOS.
    • RAM: Random Access Memory, loads the IOS and configuration file.
    • NVRAM (Non-Volatile RAM): stores the router's configuration.
    • ROM (Read Only Memory): contains code for starting and maintaining the router, e.g., Bootstrap and POST.
    • Flash memory: an EEPROM card that stores the IOS image(s).

    Interfaces

    • Examples: E0 (first Ethernet interface), E1 (second Ethernet interface).

    RAM

    • Loads the IOS and configuration file.
    • Stores routing tables.
    • The amount of RAM needed depends on the size of the IOS image and configuration file.

    NVRAM

    • Stores the router's configuration.
    • Configuration is saved in NVRAM when the router is configured.
    • NVRAM is not erased when the router is reloaded or switched off.

    ROM

    • Contains code for starting and maintaining the router.
    • Code is set from the factory and is Read Only.

    Flash Memory

    • An EEPROM card that stores the IOS image(s).
    • Can be written to or deleted from the router's console.

    CLI Modes

    • Interface configuration mode: configures interfaces, assigns IP addresses, and brings up interfaces.
    • ROMMON mode: entered by interrupting the boot process, used for password recovery or backing up the IOS on a device like a TFTP server.
    • Enable mode: uses the command "Router> enable" to enter privileged mode.
    • Configuration mode: uses the command "Router#configure terminal" to enter global configuration mode.

    Router Configuration

    • Uses the command "Router(config)#hostname Router1" to set the hostname.
    • Uses the command "Router1(config)#interface fastethernet 0/0" to enter interface configuration mode.
    • Uses the command "Router1(config-if)#ip address 192.168.1.1 255.255.255.0" to assign an IP address to an interface.

    Router Output

    • "show ip interface brief" displays the status of interfaces, including IP addresses and protocols.
    • "show ip route" displays the routing table, including connected networks and protocols.

    • The Processor (CPU) - all Cisco routers have a main processor that takes care of the main functions of the router
    • Internetwork Operating System (IOS) - the main operating system on which the router runs
    • RXBoot Image (also known as Bootloader) - a "cut-down" version of the IOS located in the router's ROM
    • RAM (Random Access Memory) - where the router loads the IOS and the configuration file
    • NVRAM (Non-Volatile RAM) - a special memory place where the router holds its configuration
    • ROM (Read Only Memory) - used to start and maintain the router, contains code like Bootstrap and POST
    • Flash memory - a card that contains the IOS image(s) and can be written to or deleted from the router's console

    Router Interfaces and Protocols

    • FastEthernet0/0, FastEthernet0/1, Vlan1 are some of the interfaces on a Cisco router
    • An interface can be administratively down or up, and can have an IP address assigned to it
    • The no shutdown command is used to bring up an interface from down status
    • The show ip interface brief command is used to display the status of all interfaces on a router

    Configuring Router Interfaces

    • To configure an interface, use the interface command followed by the interface type and number
    • To assign an IP address to an interface, use the ip address command followed by the IP address and subnet mask
    • To bring up an interface, use the no shutdown command

    Router Configuration Basics

    • A router is a device with its own specialized Operating System (OS), having RAM, permanent storage, processor, and interfaces or ports.
    • The purpose of configuring a router is to make it ready to use in networks for forwarding traffic.

    Basic Components of Cisco Router

    • Interfaces: allow connecting the router to a LAN; examples include E0 (first Ethernet interface), E1 (second Ethernet interface), S0 (first Serial interface), S1 (second Serial interface), and BRI 0 (first B channel for Basic ISDN).
    • Processor (CPU): the main processor that takes care of the main functions of the router; generates interrupts (IRQ) to communicate with other electronic components; typically uses RISC processors.
    • Internetwork Operating System (IOS): the main operating system that gives the router its capabilities; loaded upon bootup; can be updated or downloaded from the router for backup purposes.
    • RXBoot Image: a "cut-down" version of the IOS located in the router's ROM (Read Only Memory); used to load the IOS from a network tftp server or from another router that holds multiple IOS images.
    • RAM: used to store the IOS image.
    • NVRAM: used to store the router's configuration.
    • ROM: used to store the RXBoot image.
    • Flash memory: used to store the IOS image; can be a PCMCIA Flash card.
    • Configuration Register: used to store the router's configuration.

    Router Interfaces

    • Ethernet interfaces: E0, E1, etc.
    • Serial interfaces: S0, S1, etc.
    • BRI interfaces: BRI 0, BRI 1, etc.

    Router Configuration

    • To configure a router, use the configure terminal command.
    • To set the hostname of a router, use the hostname command.
    • To configure a login banner, use the banner login command.
    • To save the router's configuration, use the write command.

    Router Status

    • Use the show ip interface brief command to display the status of the router's interfaces.
    • Use the show ip route command to display the routing table.
    • The gateway of last resort is not set if no default gateway is configured.

    Task Observations

    • In both routers, only connected networks appear in the routing table.
    • Renaming a router makes it easier to identify.
    • Configuring a login banner displays a message to users when they log in to the router.
    • Saving the router's configuration is necessary to retain the changes made.
