    EIGRP Lab1 – Configuring Basic EIGRP

    By admin | March 27, 2009

    Today, I am speaking about EIGRP configuration. EIGRP is a Cisco proprietary routing protocol loosely based on their original IGRP. EIGRP is an advanced distance-vector routing protocol, with optimizations to minimize both the routing instability incurred after topology changes, as well as the use of bandwidth and processing power in the router. Routers that support EIGRP will automatically redistribute route information to IGRP neighbors by converting the 32 bit EIGRP metric to the 24 bit IGRP metric. Most of the routing optimizations are based on the Diffusing Update Algorithm (DUAL) work from SRI, which guarantees loop-free operation and provides a mechanism for fast convergence.

    Lab objectives

    1. Learn basic configurations of EIGRP

    2. Learn the configuration method of EIGRP wildcard mask

    3. Learn auto summary and auto summary turnoff features of EIGRP

    4. Learn manual summary of EIGRP Read the rest of this entry »

    Comparing EIGRP & OSPF

    By admin | March 26, 2009

    EIGRP and OSPF are both excellent routing protocols and each provides a unique set of benefits for designing and implementing a scalable network. Both protocols can be used for a wide variety of networks from small regional networks to large global network systems. A question which is frequently asked is, "Which protocol, EIGRP or OSPF, is best?" This is not an easy question, as both protocols have their benefits. This paper compares EIGRP and OSPF and provides criteria to compare the two protocols and determine which is most suitable for your network application. The following criteria have been analyzed so that key differentiating features can be considered when selecting the routing protocol which best fits your network requirements. This paper does not cover the basic operation and features of each protocol; it compares the similar features of each protocol.
    Network Architecture – OSPF requires your network topology to be hierarchical, EIGRP does not. It is good design practice to design EIGRP hierarchically as well, but it is not required. Thus, EIGRP is more versatile from a topology standpoint, but still care must be taken to design the network correctly. Sometimes all the versatility of EIGRP allows improper network design, whereas, OSPF forces you to design in a backbone. OSPF also has limitations in number of routers in a OSPF area (guideline – maximum 40-50*) and number of areas per router (guideline – up to 3*). Thus, designing an OSPF network can be more challenging and limiting than designing an EIGRP network.

    Simulator – GNS3

    By admin | March 26, 2009

    GNS3 is a graphical network simulator that allows simulation of complex networks.

    To allow complete simulations, GNS3 is strongly linked with :

    GNS3 is an excellent complementary tool to real labs for Cisco network engineers, administrators and people wanting to pass certifications such as CCNA, CCNP, CCIP or CCIE.

    Become CCIE with Simulator FAQ

    By admin | March 26, 2009

    Should I use emulator like dynamips or buy real lab?
    Well, it depends. Dynamips is an emulator that somehow “tricks” the real IOS image so it will boot and run on standard PC. So far it can run IOS for 7200 routers, 3600, 3700 and 2600 series. So if you need to practice features outside those IOS, then you can’t do it with dynamips and must go with real lab.
    What does exactly dynamips lack of?
    Performance, even it doesn’t matter for CCIE practice lab, features that must be run in hardware such as certain QoS, and all the features outside the supported IOS for example L2 and switching features from a normal 3550 or 3560 switch. And we need to be aware that if there is any issue, we need to be able to identify if the issue is from wrong config, IOS bugs, or bug from the dynamips itself. With real lab, it’s just wrong config and IOS bugs.

    Simulator – Boson NetSim for CCNP 7.06(Crack)

    By admin | March 26, 2009

    Boson NetSim® software is an application that simulates Cisco® Systems’ networking hardware and software and is designed to aid the user in learning the Cisco IOS command structure.

    The simulate scripted labs for the end user’s experience, without actually simulating what is really happening within the network. NetSim™ utilizes Boson’s proprietary Network Simulator® and Router Simulator® software technologies along with the Boson Virtual Packet Technology® engine to create individual packets that are routed and switched through the simulated network, allowing NetSim to build an appropriate virtual routing table, and simulate true networking. This technology allows many users of the Boson NetSim to go far beyond the scope of the examples in the included labs.
    Boson offers three certification-focused products, NetSim for CCENT 7.0, NetSim for CCNA 7.0 and NetSim for CCNP 7.0. Each supports the technologies and skills you will need for the respective certifications.
    Boson NetSim software offers more versatility and support than any other aftermarket software. NetSim software also includes a comprehensive lab menu that contains lessons and labs covering routing protocols, Cisco devices, switching, topological design, and much more.
