Routing method

Static and dynamic routing

INTRODUCTION TO ROUTING PROTOCOL

Introduction The main function of the network layer is Addressing and routing

Routing is a function which is responsible for bringing the data passes

through a set of network by choosing the best path to pass the data

Routing tasks will be carried out in the network device called a router

Router The router is a hardware network that duty or function to connects two

or more networks

Type the router: Computers that we enable Router

Special equipment is designed as a Router

Task router forwarding data (IP Function Forward must be enabled) using the routing protocol (Routing Algorithm)

Data is governed by the Routed Protocol

Default Gateway

In order for Router can forward data, existing computers on the network must assign the router to forward data

Assignment is done by setting the default gateway computer to the router

If we do not set the default gateway then certainly the LAN can not be connected to other networks

Direct delivery (direct connect)

IndirectDelivery (indirect connect)

The IP Address Changes

Introduction to Routing Protocols

Routing protocols Protocols used by routers to make path determination choices and to share

those choices with other routers

Hop count The number of routers a packet must pass through to reach a particular

network

Metric A value used to define the suitability of a particular route

Routers use metrics to determine which routes are better than other routes

ROUTING METHODS

Next-hop routing

Network-specific routing

Host-specificrouting

Default Routing

STATIC VERSUS

DYNAMIC ROUTING

How to Build a Routing Table

Static Routing

Built based on the definition of administrator

Administrators must be careful, the only one fail of the network routing table is not connected

Dynamic Routing

Automatically routers routing path, by exchanging information between routers using the tftp protocol

Dynamic algorithm categories:

| Distance Vector

| Link State

| Hybrid

A static routing tablecontains information entered manually.

A dynamic routing table is updated periodically using one of the dynamicrouting protocols such as RIP and OSPF

Static and Dynamic Routing

Static Routing Is a filling mechanism for the routing table manually performed by admin on

each router

The advantage:

Relieve existing processors work on router

No BW that used for the exchange of information between routers routing table contents

Higher security level vs. other mechanisms

Disadvantages:

Admin must know information of each connected router network

If there are any additions / changes to network topology admin must change the contents of the routing table

Unsuited for large networks

Dynamic Routing Routing protocol is communication between the routers

Routing protocol allows routers to share information about the network and the connection between the router

The router uses this information to build and improve its routing table

Routing protocol is different from the routed protocol.

Examples of routing protocols: Routing Information Protocol (RIP)

Interior Gateway Routing Protocol (IGRP)

Enhanced Interior Gateway Routing Protocol (EIGRP)

Open Shortest Path First (OSPF)

The objectives Routing Protocol The main purpose of routing protocols is to build and improve the routing

table.

This table contains the networks and network interfaces associated with the current network

Routers use routing protocols to manage information received from other routers and each interfaces, as occurred in the routing configuration manually

Routing protocol learn all that routers, putting the best route to the routing table, and also delete the route when the route is no longer valid.

The router uses the information in the routing table to pass the packets routed protocol
