Introduction to Routing and Packet Forwarding

Inside the Router

Routers are Computers

1800 Router Front
1800 Router Back

Router CPU and Memory

1800 Router Inside. PSU,HWIC,HWIC,Fan,Ram,NVRAM,AIM,CPU from left to right, top to bottom
1841 Router.

Internetwork Operating System

Der findes forskellige IOS'er der har forskellige freatures.

Cisco IOS packaging framework

Static Routing

Static Routes

Use Static routes when:

  • A network consists of only a few routers
  • A network is connected to the Internet only through a single ISP
  • A large network is configured in a hub-and-spoke topology

Dynamic Routing

Dynamic routing
Jobs of Dynamic Routing Protocols
  • Network Discovery
  • Maintaining Routing Tables



IP Routing Protocols

  • RIP (Routing Information Protocol)
  • IGRP (Interior Gateway Routing Protocol)
  • EIGRP (Enhanced Interior Gateway Routing Protocol)
  • OSPF (Open Shortest Path First)
  • IS-IS (Intermediate System-to-Intermediate System)
  • BGP (Border Gateway Protocol)
