Cisco Instructors League Table

Okay this is just a bit of fun, but essentially the following is a list of Cisco instructors that I have rated based on materials I have personally seen/used and how engaging and easy it is for me to absorb their presentation of these materials (typically going on video presentations rather than workbooks etc)

Please post your ‘league table’ in the comments, it will be interesting to see other peoples ‘rankings’ on Cisco Instructors.

Any instructors name that does not appear on this list is purely because I have yet to personally see / review their material.

Also it has to be said, this is my own personal ranking and does not apply to everyone! Each instructor are brilliant but my table lists them in order for me based on the fore-mentioned criteria. Based on the same criteria, this may be different for you.

1) Jeremy Cioara from CBT Nuggets

  • He makes Cisco certification fun and very attractive! He’s the reason why I chose this path! He’s both my role model and my hero! All geeks should aspire to be like Jeremy! What really makes Jeremy special is the analogies he uses to explain technical concepts! I think everyone remembers the Star Trek Spock and WRED/QoS analogy!

2) Marko Milivojevic from IP Expert

  • I like his white board explanations and the fact he builds everything from the ground up in his vLectures (and his frequent moans about Adobe – Classic!)

3) Keith Barker formerly from INE

  • His video companion series are really engaging to watch. I like that he will show you more than one way of verifying things. Watching people on the console can sometimes be boring, but Keith always injects just enough humour to keep you watching more.

4) Anthony Sequeira from INE

  • His enthusiasm and passion for the subject really shines through. He’s also easy on the ears!

    5) Joe Astorino from IP Expert

    • To be fair, I’ve only seen one of his presentations which is a vLecture on IPV6. But I thought it was real good. Hope he does more!

    6) Kevin Wallace from Cisco

    • He is a really good instructor, however I do find that his material, though very well presented, leaves me with a number of unanswered questions. Maybe because his videos are designed to be very brief but to the point, more ideal to those nearer their exam date.

    7) Chris Bryant from Train Signal

    • Chris goes into real granular details which is a good thing. I used a Chris and Jeremy combo when tackling my CCNP and it went hand in hand. His FREE 3 minute YouTube videos are really good to watch as a quick refresher!

    8 ) Tyson Scott from IP Expert

    • I find Tyson’s blogs and emails very engaging and interesting to read.

    9) Scott Morris formerly from IP Expert / INE

    • He clearly knows his stuff, however I do find myself confused a lot of the times when I listen to his audio classes and his older BLS videos.

    Policy Based Routing Lab Tips

    • Works only on the ingress of an interface.
    • ip policy route-map under the interface is PBR for transit traffic.
    • ip local policy route-map under global config is PBR for traffic sourced/destined by the router itself.

    In-Lab To Do List

    • Do not spend more than 30 minutes reading the lab task and drawing a rough sketch of the network diagram.
    • If you want to test / try something that violates the exam, make sure you save your config, do what it is you want to do and then revert back by using configure replace nvram:startup-config force
    • Use a TCLSH script after redistribution and also once at the end of the lab, especially when doing the security section.
    • If you really can’t do a task at all, then cheat it. Do it the way you know I.e. if it says don’t use a route-map, then use a route-map. This way you’ll loose points for this task but won’t loose points for future tasks that relies on this task working.
    • Don’t spend an excessive amount of time on a non-core task that doesn’t affect critical network operations.
    • Skim read each task and note the task number and in one sentence what you think it is asking for e.g. 3.2 OSPF virtual-links. This will help also connect dependant tasks, e.g. 4,3 MPLS peering relies on 3.3 OSPF loopback advertisements.
    • Create three columns, Column one for task numbers you definitely think you got in the bag, Column two for tasks that you have completely skipped or incomplete and the final column being one that you are not to certain that you have completed correctly.
    • enabled debug ip routing on all routers.

    Reflexive Lists Lab Tips

    • Allows traffic from INSIDE > OUTSIDE to return back via the evaluate #TAG# command. This is the ACL applied inbound on the outside interface.
    • evaluate #TAG# command looks at the access list for traffic going out. This is the ACL applied outbound on the outside interface and uses permit traffic reflect #TAG#. e.g. permit tcp any any reflect MY_REFLECT
    • Generally apply these to the ‘outside’ interface to control both ‘outside’ and ‘inside’ interfaces. So anything in the ACL_OUT will then be inspected by the evaluate #TAG# in the ACL_IN and create dynamic ACL to allow that traffic in.
    • Verify by doing show ip access-list MY_REFLECT (#tag#) – You will see the dynamic ACL entry providing that you have triggered it.
    • If TCP traffic, such as Telnet, is allowed out then you may need to use the established key word in the ACL_OUT as this simulates a stateful inspection and will allow the return traffic based on the ACK bit.
