3. What Is Routing ?
Routing is the process of selecting paths in a network
along which to send network traffic.
Routing is performed for many kinds of networks,
including the telephone network (circuit switching),
electronic data networks (such as the Internet), and
transportation networks.
Types Of Routing:
1.Static Routing
2.Dynamic Routing
5. Routing Protocol
A routing protocol specifies how routers communicate
with each other, disseminating information that enables
them to select routes between any two nodes on a
computer network.
Routing algorithms determine the specific choice of route.
Each router has a priority knowledge only of networks
attached to it directly.
A routing protocol shares this information first among
immediate neighbors, and then throughout the network.
6. Although there are many types of routing
protocols, But Here I have Discussed Few Of
them Only :
Routing Protocols

7. RIP ( Routing Information Protocol)
The Routing Information Protocol (RIP) is one of the oldest
Distance Vector routing Protocol, which employs the hop
count as a routing metric. RIP prevents routing loops by
implementing a limit on the number of hops allowed in a
path from the source to a destination.
Some important Points :
1. Maximum number of hops allowed for RIP is 15
2. Each RIP router transmitted full updates every 30
seconds
3. RIP uses the (UDP) as its transport protocol,
4. It Assigned the reserved port number 520
8. Versions of the Routing Information

9. Command Used To Confing RIP Protocols
For Router :
For Router 0
R0>Enable
R0#Config t
R0(config)#int f0/0
R0(config)#ip add 15.0.0.1 255.0.0.0
# no shut
R0# config t
R0(config)# Router rip
#net 10.1.1.0
For Router 1
R1>Enable
R1#Config t
R1(config)#int f0/0
R1(config)#ip add 15.0.0.2 255.0.0.0
# no shut
R1# config t
R1(config)# Router rip
#net 20.1.1.0
#net 10.1.1.0
For Verifcation We have used :
Route # ping 15.0.0.1
Route # do Sh Ip Protocols Command used to
check the Protocols details
10. Example :
F0/0
F0/0
Ip Add 15.0.0.1 Ip add 15.0.0.2
Network : 10.1.1.0 for R0 Network : 20.1.1.0 for R1
RIP Configuration Example
11. OSPF : Open Shortest Path First
Open Shortest Path First : is an Open standard Routing
Protocols that’s Been implemented by a wide variety of
Network Vendors.
OSPF Works by using the Dijkstra Algorithm.First , a
Shortest path tree is constructed , and then the routing
table is populated with the Resulting best path.
Features Of OSPF
1.Minimize Routing update traffic
2.Allow Scalability
3.Unlimited Hop Count
4.Allow Multi-vendors Deployment
12. Example
Ip 10.1.1.1
ip 10.1.1.2
Ip 15.0.0.1
Ip 15.0.0.2 ip 172.16.0.1
ip 172.16.0.2
Ip 20.1.1.1
Ip 20.1.1.2
