![ 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](https://image.slidesharecdn.com/ducat-151125135240-lva1-app6891/85/Ducat-14-320.jpg)

- 2. Getting a job is as difficult as beating the crowd because being in the corporate world demands a lot from the applicant because of which the applicants are putting their best, which results in the increment of difficulty level. You can see each and every thing is connected but the solution of this problem is either spending years to reach to a desired position or come to Ducat. At Ducat we provide the entire necessary computer training which helps the newbies and also the experienced workers so that they can achieve better recognition in this competitive world. Like other educational and training industry at Ducat you will be offered varieties programs but the instructors makes the difference and make Ducat stand out from others. .
- 3. WHAT TYPES OF SERVICES ARE OFFERED BY DUCAT? • Software Development • Instructor led campus • Workshops and Placement Service
- 4. 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.
- 5. 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.
- 7. 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.
- 8. 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
- 9. 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
- 10. 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
- 11. 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
- 12. 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
- 13. 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
- 14. 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
- 15. 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
- 16. 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.
- 17. 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

- 19. 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.
- 20. 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.
- 21. 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.
- 22. 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.
