WHAT IS CISCO PACKET TRACER
network or data network is
a telecommunications network that allows computers to
networks support applications such as
access to the World Wide Web, shared use
of application and storage servers, printers, and fax
machines, and use of email and instant
devices that originate, route and terminate the
data are called network nodes. Nodes can
include hosts such as servers and personal computers,
as well as networking hardware.
Two devices are said to be networked when
a process in one device is able to exchange information
with a process in another device.
CISCO PACKET TRACER
Packet Tracer is a powerful network simulation
program that allows students to experiment with
network behavior and ask “what if” questions.
integral part of the Networking Academy
comprehensive learning experience, Packet Tracer
provides simulation, visualization, authoring,
assessment, and collaboration capabilities and
facilitates the teaching and learning of complex
project is based on corporate network and NOCs
(Network Operating Centers), where we also manage
stub networks (Server administration, user
administration and all).
is done and executed in Cisco Packet
Tracer by making a corporate network scenario by using
some routers, switches, PC’s and Servers and showing
the inter connection between the devices
ROUTING INFORMATION PROTOCOL.
an intra-domain routing protocol used inside an
of the most simple and earlier routing protocols
based on distance vector routing.
RIPv1 and RIPv2
Static Routing and Dynamic Routing
RIPv1 and RIPv2
In RIPv1 it does not send subnet mask information in the routing
update advertisements, which is a characteristics of classful routing
RIPv1 enabled networks are vulnerable to attacks as the RIPv1
also does not support router authentication.
Due to faults in the original RIP specification(RIPv1), RIP version
2(RIPv2) was developed in 1993 and got support for its
standardization in 1998.
It included the capability to carry the subnet mask information, thus
supporting Classless Inter-Domain Routing(CIDR).
STATIC ROUTING AND DYNAMIC ROUTING
Routing is simply the process in which the system
network administrator manually configures the network
routers with all the information necessary for successful
Dynamic Routing, the routing protocol operating on
the router is responsible for the creation, maintenance
and updating of the dynamic routing table.
Routing Protocols like EIGRP,OSPF etc are supported
only in Dynamic Routing.
DYNAMIC HOST CONFIGURATION
a network protocol used to configure devices that
are connected to a network so they can communicate
on that network using the Internet Protocol (IP).
is implemented in a client-server model, in
which DHCP clients request configuration data, such as
an IP address, a default route, and one or more DNS
server addresses from a DHCPserver.
ACCESS LIST PROTOCOL
a group of statements that defines a pattern that
can be found in an IP packet.
packet comes through an interface with an
associated access list, the list is scanned from top to
bottom in the exact order that it entered for a pattern
that matches the incoming packet.
A permit or deny rule associated with the pattern
determines that packet’s fate.
network is an enterprise's communications
backbone that helps connect computers and related
devices across departments and workgroup networks,
facilitating insight and data accessibility.
corporate network reduces communication
protocols, facilitating system and device interoperability,
as well as improved internal and external enterprise
