  • Choosing an IP routing protocol is an important step. The right protocol can make your routing operate efficiently, and the wrong one can make your life difficult. Each protocol has its own pros and cons, and works better in some situations than others. In this paper, we explore the strengths and weakness of RIP, EIGRP, OSPF, and IS-IS, and discuss when it is appropriate to use each. We will evaluate each protocol in terms of five criteria: • Convergence speed • Ease of use • Network topology required • Vendor support • IPv6 support...

  • Link-State Routing Protocols. Objectives: Describe the basic features & concepts of link-state p routing protocols. Distance vector routing protocols are like road signs because routers must make preferred path decisions based on a distance or metric to a network. Link-state routing protocols are more like a road map because they create a topological map of the network and each router uses this map to determine the shortest path to each network. The ultimate objective is that every router receives all of the link-state information about all other routers in the routing area.

  • Most routing protocols fall into one of two classes: distance vector or link state. The basics of distance vector routing protocols are examined here; the next section covers link state routing protocols. Most distance vector algorithms are based on the work done of R. E. Bellman, L. R. Ford, and D. R. Fulkerson, and for this reason occasionally are referred to as BellmanFord or FordFulkerson algorithms. A notable exception is EIGRP, which is based on an algorithm developed by J. J. Garcia Luna Aceves....

  • 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.

  • 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

  • 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...

  • 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.
