presentation on ccna(networking & troubleshooting)
DESCRIPTION
CISCO certified Network Associate (CCNA) Routing and Troubleshooting basics are here in these slides. This was by 2 months internship at CISCO. Thought it might be of some help to you all. Enjoy.TRANSCRIPT

IP ADDRESSING Two Types:- IPv4(Internet Protocol version 4):-
1. 32 bit Binary Address2. Represented with Dots. E.g.:- 192.168.16.1/24
IPv6(Internet Protocol version 6):-1. 128 Bits Binary Address2. Represented with Colons & Double Columns E.g.:- 2000::7:2100:0:0:2121
INTERNET PROTOCOL VERSION 4(IPV4) Two Types:-
A. Public IP’s Routable IP’sB. Private IP’s Personal
Uses(Networking) Classification of IP Addresses:-
Class A : Class B : Class C : Class D : Multicast Class E : Research

SUBNETTING Subnetting is logically dividing the network by extending the 1’s used in Subnet Mask. Advantage:-
Can divide network in smaller parts.Restrict Broadcast traffic.Security.Simplified Administration.
ROUTERS
Router is an internetworking component, that connects networks which are at different geographical locations.
Routers
Modular
Modular Routers
These type of routers have upgradable slots, and the number of ports can be increased just by adding cards in the slots. E.g.:-Cisco Routers from 2600,…, 12000
Fixed Routers
These types of routers have fixed number of ports. E.g.:- Cisco Routers from 700,…, 2500
Fixed
ROUTING Static Dynamic Default
When the destination is known, static and dynamic routing is done. Static routing is done by the users.
For unknown destinations, default routing is employed.
In dynamic routing, path is fixed by the protocol. Path changes depending on the length of the path. Always the shortest path is preferred. Paths are stored in the routing table.
RIP(ROUTING INFORMATION PROTOCOL)
A Distance Vector Routing Protocol.
“Hop count metric” selects the path. It is the only criteria. Maximum is 15.
Route updates are broadcasted after every 30 seconds.
RIPv1 uses only Classful Routing.
EIGRP(ENHANCED INTERIOR GATEWAY ROUTING PROTOCOL) Supports IPv4 and IPv6 via Protocol-
Dependent Modules.
Considered Classless.
Efficient Neighbor discovery.
Maximum Hop Count is 255. By Default it is 100.
Uses Reliable Transport Protocol(RTP).
OSPF (OPEN SHORTEST PATH FIRST)
An Open standard Routing Protocol.
A Link-State Routing Protocol.
Minimizes Routing Update Traffic.
Has unlimited Hop Count.
VLAN (VIRTUAL LAN)
VLANs helps reduce the cost of moving employees from one location to another
VLAN TRUNKING PROTOCOL
VLAN trunking protocol (VTP)A layer 2 messaging protocol that manages all
the changes to the VLANs across networks. VTP domains
VTP devices are organized into domains. Each switch can only be in one VTP domain at a time.
VTP device modes:-ServerClientTransparent
FRAME RELAY It is a packet-switched, connection-oriented, WAN service. It operates at the data link layer of the OSI reference model.
