Certifications Unleashed

All you need to certify yourself

Cisco: The Complete Reference is a lofty title for a book, and one that you could take
in a multitude of different directions. Some think that a book with this title should be
the “end all and be all” of Cisco books, including every possible Cisco technology and
the most obscure details of those technologies. Unfortunately, that book would
consist of over 50,000 pages, and it would be obsolete by the time you got it. (Cisco
has been trying for years to write that book; it’s called the Cisco web site, and it’s still
not complete.)

  • Latest CCNA Syllabus

    You can take either of the following paths in achieving your certification:

    1) Single Exam

    Exam # 640-802

    2) Two Exams

    Exam # 640-822  ICND1

    Exam # 640-816  ICND2

    Syllabus of each is described below:

    1) Syllabus for Single Exam (640-802) :-

    Exam Topics

    The following topics are general guidelines for the content likely to be included on the Cisco Certified Network Associate exam. However, other related topics may also appear on any specific delivery of the exam. In order to better reflect the contents of the exam and for clarity purposes, the guidelines below may change at any time without notice.

    Describe how a network works

    • Describe the purpose and functions of various network devices
    • Select the components required to meet a network specification
    • Use the OSI and TCP/IP models and their associated protocols to explain how data flows in a network
    • Describe common networked applications including web applications
    • Describe the purpose and basic operation of the protocols in the OSI and TCP models
    • Describe the impact of applications (Voice Over IP and Video Over IP) on a network
    • Interpret network diagrams
    • Determine the path between two hosts across a network
    • Describe the components required for network and Internet communications
    • Identify and correct common network problems at layers 1, 2, 3 and 7 using a layered model approach
    • Differentiate between LAN/WAN operation and features

  • Cisco Certified Network Associate (CCNA®) validates the ability to install, configure, operate, and troubleshoot medium-size route and switched networks, including implementation and verification of connections to remote sites in a WAN. CCNA curriculum includes basic mitigation of security threats, introduction to wireless networking concepts and terminology, and performance-based skills. This new curriculum also includes (but is not limited to) the use of these protocols: IP, Enhanced Interior Gateway Routing Protocol (EIGRP), Serial Line Interface Protocol Frame Relay, Routing Information Protocol Version 2 (RIPv2),VLANs, Ethernet, access control lists (ACLs).

  • The output of “sh ip route eigrp” is shown in the below snapshot:

    eigrp

     

     See the Routing table and you will find all the 10 subnets in 10.0.0.0 network mentioned separately as shown below; (this 10 subnets include all the networks including the static routes and others in addition to EIGRP.So, don’t confuse

  • EIGRP Network Advertisement

    When we type “network 10.0.0.0”, the EIGRP process looks at 10.0.0.0 network and turns on EIGRP on all the interfaces whose IP Address is in the subnet 10.0.0.0. Then EIGRP advertise the network which is the IP Address of the interface. For example, when I mentioned the below IP address on an interface

    1

    EIGRP process advertised 172.16.0.0/24 which was under the interface as shown below:

    When a router advertises a default route to another router, it thinks that it has route to all the networks, that’s why it’s summarizing all the routes as one default route. Considering this, there is no need for the default route installed on it since it already has an individual route to every network (according to router thinking). So, it installs a route with a default route directing to NULL interface.

  • Cause Analysis

    Routing table of Corp Router showed RIP entry instead of EIGRP.

    Handaling Process &  Solution

    For resolving this problem I undertook the following steps:

     

    1)    After applying redistribution on R3, I checked that the router 871W and hostd were able to see all the routes on the other side of R3 as RIP routes.     That was normal.

    2)    Then I checked Corp Router and found out that Corp showed the route 10.1.12.0 as a RIP Entry. Corp Router was basically running both RIP and EIGRP. Static routes were also installed in Corp with AD of 150.

    3)     I stopped RIP on Corp, and checked again. This time a static route took the place of RIP Entry for 10.1.12.0 network.

          4)   I checked the topology table of EIGRP and found the following error:

     

             eigrp1

     

    The route to 10.1.12.0 showed “FD is Inaccessible” which meant that the EIGRP route in the topology table for the network 10.1.12.0 was not being used for the routing table.

          5) After that I removed static entry as well. EIGRP route was successfully added to the routing table with AD of 170 as shown below

     

              untitled

         6) The route from redistribution is considered as an external route in EIGRP. That’s why we saw RIP and static route in the routing table instead of   

              EIGRP.
