Presentation on CCNA(Networking & Troubleshooting)


Published on

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.

Presentation on CCNA(Networking & Troubleshooting)

  1. 1. Submitted by:- ARUNABH DEKA Roll no:- 2019 E.C.E (2008-2012)
  2. 2. A. What is Cisco? A. B. C. The MICROSOFT of Networking. Established in 1984 at San Francisco, HQ-San Jose, California. Founders:A. B. C. Lan Bosack Sandy Lerner John T. Chambers(Chairman & CEO)
  3. 3. Switches Hubs Routers Bridges
  4. 4. Straight Through Cable
  5. 5. Two Types: IPv4(Internet Protocol version 4): 1. 2. 32 bit Binary Address Represented with Dots. E.g.:-  IPv6(Internet 1. 2. Protocol version 6):- 128 Bits Binary Address Represented with Colons & Double Columns E.g.:- 2000::7:2100:0:0:2121
  6. 6.  Two Types:A. B.  Public IP’s Private IP’s Routable IP’s Personal Uses(Networking) Classification of IP Addresses:8 bits      Class A Class B Class C Class D Class E : : : : : 8 bits 8 bits 8 bits Network Host Host Host Network Network Host Host Network Network Network Host Multicast Research
  7. 7. 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.
  8. 8. Router is an internetworking component, that connects networks which are at different geographical locations.
  9. 9. Routers Modular Fixed 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
  10. 10.    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.
  11. 11. 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.
  12. 12.  Supports IPv4 and IPv6 via ProtocolDependent Modules.  Considered Classless.  Efficient Neighbor discovery.   Maximum Hop Count is 255. By Default it is 100. Uses Reliable Transport Protocol(RTP).
  13. 13.  An Open standard Routing Protocol.  A Link-State Routing Protocol.  Minimizes Routing Update Traffic.  Has unlimited Hop Count.
  14. 14. VLANs helps reduce the cost of moving employees from one location to another
  15. 15.  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: Server  Client  Transparent
  16. 16.   It is a packet-switched, connection-oriented, WAN service. It operates at the data link layer of the OSI reference model.
