Building a routing table

4

There are two basic methods of building a routing

table:

1. Static Routing

2. Dynamic Routing


Dynamic Route

5

A dynamic routing table is created, maintained, and updated by a routing protocol running on the router.

Examples of routing protocols include

RIP (Routing Information Protocol)

OSPF (Open Shortest Path First)

EIGRP (Enhanced Interior Gateway Routing Protocol)

Dynamic routing table is updated periodically using one of the dynamic routing protocols such as RIP, OSPF, or EIGRP.

Whenever there is a change in the Internet, such as the shutdown of a router or breaking of a link, the dynamic routing protocols update all of the tables in the routers.


RIP (Routing Information Protocol) 6

Routing Information Protocol (RIP) is a standards-based

on distance-vector algorithm to exchange routing

information.

RIP uses hop count to determine the best path between two

locations.

Hop count is the number of routers the packet must go

through till it reaches the destination network.

The maximum allowable number of hops a packet can

traverse in an IP network implementing RIP is 15 hops

(small networks)

There are two version of RIP: RIP and RIPv2


RIP properties 7

1- Based on distance-vector.

2- Each router has only one table which is “Routing Table”

3- Broadcast the routing table to all routers (broadcast address 255.255.255.255)

4- Sending tables each 30 seconds even if there is change or not overload

5- Can support classful addresses only

6- Letter that used to represent RIP on the routing table is R

7- the Administrative distance value of RIP is 120

8- RIP uses the hop count as metric or cost .

9- Suitable for small networks (The maximum allowable number of hops is 15

hops, if the destination is on 16th hop then it will be a host unreachable for RIP)


RIPv2

8

RIPv2 is an improvement of RIP

RIPv2 properties :

1. Can support classless as well as classful addresses

2. Multicast the routing table to routers that used RIP as routing

protocol only (multicast address is 224.0.0.9) less

overload


How to configure RIP on the router?

9

RIP configuration

For each router, you have to configure only its directly connected networks by using the following command ( in the global configuration mode):

Router rip

network [network address]

.

.

exit

Command description

Router rip Puts you in router rip configuration mode

Network [network address] Tell the routing protocol what network to

advertise (followed by the network address)

in dotted-decimal notation

Exit To exit from the router rip configuration mode.
