  1. 1. TRAINED BY –Ravinder kumar (Gurukul Technical Institute) SUBMITTED BY –Tarun Khaneja ROLL NO. -2110045 contact no. - 09034406598 PRESENTATION ON CCNA
  2. 2. INTRODUCTION  CCNA stands for Cisco Certified Network Associate  It gives the information about networking ,its types and its application .  Networking is very important as it provides communication.  It is also very useful as it helps in resource sharing.  Thus , overall it is a cost saving technique.
  3. 3. TYPES OF NETWORKING  LAN – It stands for local area network. Eg: network within a campus .  MAN – It stands for metropolitan area network. Eg: network connecting various cities.  WAN – It stands for wide area network. Eg : internet on a whole world.

  5. 5. Subnetting and Supernetting About subnetting & Supernetting In subnetting, a network is divided into several smaller subnetwork with each subnetwork(or subnet) having its own subnetwork address. In supernetting, an organization can combine several class C addresses to create a larger range of addresses(supernetwork). SUBNETTING Class A, B, C in IP addressing are designed with two levels of hierarchy. The organization has two-level hierarchical addressing, but it cannot have more than one physical network./ The host cannot be organized into groups, and all of the hosts are at the same level./ The organization has one network with many hosts. One solution to this problem is subnetting, the further division of a network into smaller networks called subnetworks.
  6. 6. EXAMPLE OF SUBNETTING ( Example / Class A) An organization with a class A address at least 1,000 subnetworks. Find the subnet mask and configuration of each subnetwork. (Solution) 1. There is a need for at least 1,000 subnetworks.(we need at least 1,002 subnetworks to allow for the all-1s and all-0s subnetids) 2. This means that the minimum number of bits to be allocated for subnetting should be 10, (29 < 1,002 < 210). 3. 14 bits are left to define the hostids. Subnet mask (11000000 = 192).
  7. 7. Range of addresses
  8. 8. Subnetworks in example
  9. 9. Classless Interdomain Routing(CIDR) Supernetting means assigning a set of class C addresses to an organization that needs more than 254 host addresses. However , when these class C addresses are entered into the routing table, each occupies one entry in the routing table./ 256 entries in the routing table. The classless interdomain routing(CIDR) technique is devised to reduce the number of routing table entries. In this technique, instead of entering each single class C address with its corresponding default mask(255.255.255.0), the router can use the supernet mask and the lowest network address in the group.
  10. 10. CIDR
  11. 11. Hubs vs. switches Hubs – less expensive, used in a very small LAN where low throughput is OK Switches – segments collision domains, interconnects network segments, more expensive, but performance makes it cost effective.
  12. 12. It is a layer 3 or network layer device. In this there is no broadcast. It is WAN technology device. It is useful to connect different networks. Packet filtering & it finds the best path selection. ROUTERS
  13. 13. Router Configuration  Router always has two configurations:  Running configuration  In RAM, determines how the router is currently operating  Is modified using the configure command  To see it: show running-config  Startup confguration  In NVRAM, determines how the router will operate after next reload  Is modified using the copy command  To see it: show startup-config
  14. 14. Router Access Modes  User EXEC mode - limited examination of router – Router>  Privileged EXEC mode - detailed examination of router, debugging, testing, file manipulation – Router#  ROM Monitor - useful for password recovery & new IOS upload session  Setup Mode – available when router has no startup- config file
  15. 15. Logging Into The Router  Connect router to console port or telnet to router – router> – router>enable – password – router# – router#?  Configuring the router – Terminal (entering the commands directly) – router# configure terminal – router(config)# USER MODE PROMPT PRIVILEDGED MODE PROMPT
  16. 16. Deleting Your router’s Configuration To delete your router’s configuration  Router#erase startup-config OR  Router#write erase  Router#reload  Router will startup again, but in setup mode, since startup-config file does not exists
  17. 17. ROUTING Routing is the exchange of routes between different networks . There are three types of routing: 1. Default routing 2. Static routing 3. Dynamic routing
  18. 18.  A routing protocol is the communication used between routers.  A routing protocol allows one router to share information with other routers.  The information a router gets from another router, using a routing protocol, is used to build & maintain a routing table. Examples of routing protocols: 1. RIP [ROUTING INFORMATION PROTOCOL] 2. EIGRP[ENHANCED INTERIOR GATEWAY ROUTING PROTOCOL] 3. OSPF[OPEN SHORTEST PATH FIRST] DYNAMIC ROUTING
  19. 19. Routing Information Protocol (RIP) • RIP is a distance vector routing protocol • Hop count is used as the metric for path selection • If the hop count is greater than 15, the packet will be discarded • By default, routing updates are broadcast every 30 seconds • RIP has evolved over the years from a Classful Routing Protocol, RIP Version 1 (RIP v1), to a Classless Routing Protocol, RIP Version 2 (RIP v2). • Configuring RIP Router(config)#router rip
  20. 20. Enhanced Interior Gateway Routing Protocol (EIGRP) • Really just an enhanced version of IGRP • A Cisco proprietary routing protocol • Called a hybrid protocol, but really just an advanced distance vector protocol. • Fast convergence • Variable length subnet masks • Partial updates - only when the metric for a route changes (bounded updates) • Multiple network layer support - IP, IPX, and AppleTalk • A router running EIGRP stores all its neighbor’s routing tables so that it can quickly adapt or alternate routes.
  21. 21. Features of EIGRP  Classless Routing Protocol (VLSM, CIDR)  Faster convergence times and improved scalability  Multiprotocol support: TCP/IP, IPX/SPX, Appletalk – There is no IPX/SPX or Appletalk in CCNA or CCNP  Rapid Convergence and Better handling of routing loops – (DUAL)  Efficient Use of Bandwidth – Partial, bounded updates: Incremental updates only to the routers that need them. – Minimal bandwidth consumption: Hello packets and by default uses no more that 50% of link’s bandwidth EIGRP packets.  PDM (Protocol Dependent Module) – Keeps EIGRP modular – Different PDMs can be added to EIGRP as new routed protocols are enhanced or developed: IPv4, IPv6, IPX, and AppleTalk
  22. 22. OSPF  Open Shortest Path First  Dynamic IGP (Interior Gateway Protocol)  Use within your own network  Link state algorithm Shortest Path First A B C D 15 3 4 4 7
  23. 23. WhaT IS ACL? Routers provide basic traffic filtering capabilities, such as blocking Internet traffic, with access control lists (ACLs). An ACL is a sequential list of permit or deny statements that apply to addresses or upper-layer protocols. This module will introduce standard and extended ACLs as a means to control network traffic, and how ACLs are used as part of a security solution.
  24. 24. VLAN • VLAN stands for virtual local area network. • Devices on different VLAN must have a router to communicate with each other. • If devices are on the same VLAN, then they can communicate through a switch.
  25. 25. INTER VLAN ROUTING  A VLAN is a broadcast domain and unique ip subnet  Switches operate at layer2 (Data link Layer)  VLANS cannot communicate without L3 (Network Layer)  The L3 communication is called inter- vlan routing  Inter-vlan routing is a process of forwarding network traffic from one vlan to another using a router  The Subnets of your network facilitate the routing process.  Router interfaces can be connected to separate vlans.  Devices on vlans send traffic through the router(L3) to other vlans.
  26. 26. How to configure EIGRP with RIP on same network In this article we will discuss how can two routing protocols exist in same network? We have discussed basic of both EIGRP and RIP in our previous article. Now we will go in more depth by including both RIP and EIGRP in same network. Scenario You are the administrator at abc.com.
