STARTING ROUTER tutorials

  • When a router is started (booted up), it goes through the following sequence

  • The router checks its hardware with POST [Power On Self Test]

  • The router loads a bootstrap startup code from ROM

  • The Cisco IOS software is located and loaded using the information in the bootstrap code

  • The configuration is located and loaded.

 

ROUTER COMPONENTS

The major router components are as follow

RAM

Random Access Memory contains key software [IOS]

ROM

Read Only Memory contains startup microcode.

NVRAM

NonVolatile Random Access Memory stores the configuration

Configuration Register

Controls the bootup method

Interfaces

The interface is the physical connection to the external devices

Flash Memory

Flash contains he Cisco IOS software image
