Router Introduction in advanced level including Network Stimulation Technologies

2. •Definition:
A router is a networking device that
forwards data packets between
computer networks. It is an
internetworking device Used to
connect two or more different
Networks.
•OSI Reference Model:
Network Layer(Layer Three)
Logical Address(IP Address)
•TCP/IP Model:
Internet Layer(Layer Two)
Logical Address(IP Address)

3. Types of Routing:
• Static Routing:
It is a form of routing that occurs when a
router uses a manually configured routing
entry, rather than information from a
dynamic routing traffic.
• Dynamic Routing:
It is a process where a router can forward
data via a different route or given
destination based on the routing protocol
such as OSPF, ISIS, EIGRP, and/or BGP
to figure out what paths traffic should
take.

4. Classification of Routing Protocols
According to
1. Purpose:
Interior Gateway Protocol (IGP) or
Exterior Gateway Protocol (EGP)
2. Operation:
Distance vector protocol,
Link-state protocol, or
Path-vector protocol.
3. Behaviour:
Classful (legacy) or
Classless protocol

5. Examples of Routing
Protocols
i. RIPv1 (Legacy):
IGP, distance vector, classful
protocol.
ii. IGRP (legacy):
IGP, distance vector, classful protocol
developed by Cisco (deprecated from
12.2 IOS and later).
iii. RIPv2:
IGP, distance vector, classless
protocol.

6. iv. EIGRP:
IGP, distance vector, classless
protocol developed by Cisco.
v. OSPF:
IGP, link-state, classless
protocol.
vi. IS-IS:
IGP, link-state, classless
protocol.
vii. BGP:
EGP, path-vector, classless
protocol.
