Dynamic routing protocols have evolved over several years
As networks have evolved and become more complex, new routing protocols have emerged.
Most institutions have migrated to new protocols, others are still in use.
The first version of RIP was released in 1982, but some of the basic algorithms within the protocol were used on the ARPANET as early as 1969.

Enhanced Interior Gateway Routing Protocol (EIGRP)  Distance vector.  Classless routing protocol.
Released in 1992 with Cisco IOS Software Release 9.21.
Enhancement of Cisco Interior Gateway Routing Protocol (IGRP).
Both are Cisco proprietary.  Operate only on Cisco routers.The term hybrid routing protocol is sometimes used to define EIGRP.  Misleading, not a hybrid between distance vector and link-state  Solely a distance vector routing protocol.

The structure of the routing table might seem obvious.
Help you verify and troubleshoot routing issues because you will understand the routing table lookup process.
You will know exactly what the Cisco IOS software does when it searches for a route.Notice that R3 also has a 172.16.4.0/24 subnet that is disconnected, or discontiguous, from the 172.16.0.0 network that R1 and R2 share.
The effects of this discontiguous subnet are examined later in this chapter when you look at the route lookup process....

Note on Classful Routing Protocols, RIPv1 limitations
The first part of this presentation discusses the limitations of classful routing protocols such as RIPv1.
RIPv1 is used as an example, so we can see how RIPv2 a classless routing protocol does not have these same limitations.
Classful routing protocols have three major limitations:  Does not support discontiguous networks.  Does not support VLSM.  Does not support CIDR.
Instead of just “memorizing” these facts, we will demonstrate and “understand” why a classful routing protocol has these limitati...

The first protocol used was Routing Information Protocol (RIP).
RIP still popular: simple and widespread support.
Why learn RIP?  Still in use today.  Help understand fundamental concepts and comparisons of protocols  such as classful (RIPv1) and classless (RIPv2).RIP is not a protocol “on the way out.”
In fact, an IPv6 form of RIP called RIPng (next generation) is now available.

There are advantages and disadvantages to using any type of routing protocol.  Some of their inherent pitfalls, and.  Remedies to these pitfalls.
Understanding the operation of distance vector routing is critical to enabling, verifying, and troubleshooting these protocols.RIP: Routing Information Protocol originally specified in RFC 1058.  Metric: Hop count  Hop count greater than 15 means network is unreachable.  Routing updates: Broadcast/multicast every 30 seconds

Topology A Cisco 1841 router has the following interfaces: Two Fast Ethernet interfaces: FastEthernet 0/0 and FastEthernet 0/1 Two serial interfaces: Serial 0/0/0 and Serial0/0/1 l The interfaces on your routers can vary. Packet Tracer Activities are referenced throughout these chapters for additional practices.Unlike most user PCs, a router will have multiple network interfaces. l These interfaces can include a variety of connectors.

Link-State Routing Process 1. Each router learns about its own links, its own directly connected networks. (Interface is “up”) 2. Each router is responsible for meeting its neighbors on directly connected networks. (OSPF Hello packets) 3. Each router builds a link-state packet (LSP) containing the state of each directly connected link. (neighbor ID, link type, and bandwidth) 4. Each router floods the LSP to all neighbors, who then store all LSPs received in a database. Neighbors then flood the LSPs to their neighbors until all routers in the area have received the LSPs. 5.

When the ARPANET was commissioned in 1969, no one anticipated that the Internet would explode out of the humble beginnings of this research project. Over the next decade, the number of hosts on the Internet grew exponentially, from 159,000 in October 1989 to over 72 million by the end of the millennium. As of January 2007, there were over 433 million hosts on the Internet.

1.Connect devices that are separated by a broader geographical area. 2.Use the services of carriers, such as telephone companies, network providers… 3.Use serial connections.A VPN is an encrypted connection between private networks over a public network such as the Internet. Instead of using a dedicated Layer 2 connection such as a leased line, a VPN uses virtual connections called VPN tunnels, which are routed through the Internet from the private network of the company to the remote site or employee host.

Describe the basic purpose of a router – Computers that specialize in sending packets over the data network – They are responsible for interconnecting networks by selecting the best path for a packet to travel and forwarding packets to their destination Routers are the network center – Routers generally have 2 connections: • WAN connection (Connection to ISP) • LAN connection

This lab focuses on configuring a basic router-to-router WAN and then troubleshooting Layer 1 cabling problems and workstation Layer 3 IP addressing problems. Note: The two routers need to be preconfigured by the instructor or lab assistant to have the correct IP addresses on their LAN and WAN interfaces. Router A will provide the clocking signal as DCE. Use the prior lab “Basic Routed WAN” to set up this lab prior to starting the troubleshooting.
