IPexpert's Protocol Operations and Troubleshooting Series

In last couple of months, one of the most popular CCIE R&S training vendor in market - IP EXPERT released couple of books covering R&S blueprint technologies. Which I personally feel is a big effort. Since writing books not only takes time but also those should be user friendly as well. Otherwise there are always choices in terms of books. The best part about IPX books is that they not explain you technology in a very simple manner but also focus on configuration examples to make sure you really understand the concepts and also focus heavily on troubleshooting. Troubleshooting is I guess the part which most book vendors fail to cover or help you as reader to build step by step logical approach.


So far they have released four books under this series and I wish they will keep doing it for rest of important R&S technology domains.

INE Free OER/PFR V-Lecture - By Brian Dennis

PFR is one of the topics which lately most of R&S Engineers find either hard to understand or hate it ;-)


So to help students with the preparation, INE conducted a Free V-Seminar on PFR. The seminar ran for around 8 Hrs during which Brian Dennis himself walk through the advanced PFR scenarios.


PFR or Performance Routing was initially introduced as feature called OER or Optimized Edge Routing. During 12.4 series of IOS (official R&S Lab Version), the feature was not developed fully or I should say mature enough. But since the introduction of IOS 15.x Series, Feature has grown very well and I would expect more PFR to be implemented in real world as people move or migrate their networks to IOS 15. IOS 15 has many other feature which will change the network world significantly like LISP.


During the Seminar Brian also suggested that he will be running a 3 Days PFR class soon which will be covering PFR features which can be implemented in IOS 15 and are not available in IOS version 12.4


So here is the URL of V-Seminar recording:


http://www.ine.com/all-access-pass/training/playlist/ccie-rs-pfr-vseminar/-pfr--vseminar-22200011.html

Here is the URL for Cisco's official PFR Documentation page:

www.cisco.com/go/pfr

Also INE PFR Class Expect you to have some basic PFR understanding, For that I would recommend following V-Lecture from IP Expert Instructor - Tyson Scott

CCIE R&S Routing Study Plan - IPv4

Every once in a while I get this request to write a CCIE R&S Routing Study Plan similar to CCIE R&S Switching study plan :

http://deepakarora1984.blogspot.com/2010/03/ccie-r-switching-study-plan.html

So lets list all routing topics and allow me to list my attack plan for each of those starting with RIP today... I'll keep adding for rest soon...

1. RIPv2

2. EIGRP

3. OSPF

4. BGP

5. REDISTRIBUTION

6. Learning each of above mentioned routing protocol from MPLS prospective.

Misc :

1. ODR

2. PBR

3. OER/PFR

4. Understanding CEF & IOS Switching

5. Understanding Load Sharing Vs Load Balancing

6. Protocol independent features

So lets begin with RIP for today :)

  RIP

####

1. INE R&S ATC VODs RIP Lectures 

http://www.ine.com/self-paced/ccie-routing-switching/bootcamps/ccie-routing-switching-advanced-technologies-class.htm

2. Jeff Doyle's TCP/IP Vol 1(2nd Edition) 

Two Chapters Just Talking about RIP along with some very good corner case scenarios. Technically one chapter talks about RIPv1 which is not on blueprint but still a good read to grasp fundamentals.

Make sure you test all RIP labs given in this book along the way.

3. Read about RIP from Ruhann's R&S Handbook :

http://routing-bits.com/handbook-for-rs/

4. Enough Theory ? .... Not yet :) ... Move onto RIP Technology Page

 http://www.cisco.com/en/US/tech/tk365/tk554/tsd_technology_support_sub-protocol_home.html

5. Okay... Enough Theory...Time to get some hands dirty with RIP Labs.

Alternatively you can follow any good R&S workbook vendor's RIP Technology Labs like - INE (www.ine.com) , IP Expert (www.ipexpert.com) Or Narbik (www.micronicstraining.com) ...Whatever works best for you

6. Some important blog posts.

http://ardenpackeer.com/routing-protocols/tutorial-troubleshooting-split-horizon-issues-part-2/

7. Enough ? :)... Not Yet... Lets move to final phase and read through IOS 12.4T RIP configuration & command reference guides along with 12.4 T IOS Independent Feature Guide/Command Ref and make sure next time you know where to find what.

http://www.cisco.com/en/US/docs/ios-xml/ios/iproute_rip/configuration/12-4t/irr-12-4t-book.html

http://www.cisco.com/en/US/docs/ios-xml/ios/iproute_pi/command/iri-cr-book.html

8. Though by this time you should be good with RIP troubleshooting as well, but just to add one extra bit, INE R&S Troubleshooting Class On Demand is an excellent resource to prepare for this part.

Redistribution Mock Lab - The Crazy Stuff

Last year while I was preparing for my R&S Lab, I felt I was not well prepared for complex redistribution scenarios. I took a look at Vol-1 workbooks outline from IP Expert and Internetwork Expert but none of them seems to cover Redistribution as part of Technology labs. So I thought to create some ugly redistribution lab my self.

So let me quickly share the physical & logical topology here with you guys along with initials.

Requirement is simple - to perform mutual redistribution at all redistribution points without creating a routing loop.

I would like to mention here that I am not looking for optimal routing here after redistribution, R4 has 3 routing protocols running, so make sure all three have mutual redistribution.

How To Prepare For CCNA - An Insight Look

In Recent months I have received so many email from all around the world from people asking about how to prepare for CCNA.

So today as I am resuming blogging back so thought to start with this. I mean how I passed my CCNA back in sep 2005.

Back in 2005 there were not much resources available to prepare for CCNA like today. I was working for a company as System Support Engineer (Desktops, Servers, High Speed Line Printers etc). Life was pretty hard and income was quiet less...actually 75 USD a month. At that time a close friend and mentor SUSHIL SHARDA who was working for same client like I was on behalf of another company asked me to try my luck in Networking Industry. He encouraged me to go for CCNA. I took his suggestion and started preparing for CCNA 640-801 exam.

I used the following material or In brief CCNA Complete Study package written by great CCIE Instructor Chris Bryant (CCIE#12933).

http://www.thebryantadvantage.com/UltimateCCNAStudyPackage.html

The CCNA package has got everything you need to pass CCNA exam like :

1. CCNA Study Book
2. CCNA Lab Book (Containing CCNA Lab Scenarios for practice and to put  
    your theory and skills on test for practice)
3. Binary Maths book which covers all you need to know about Subnetting
4. A book covering how to convert from Binary to hex and decimal   
   and vice versa.
5. CCNA Practice Engine
6. CCNA command handbook etc

This all stuff is gonna cost you just 25 USD.

Apart from this I used CCNA Book from Todd Lammle. In those days GNS was not available so I used most of time on real equipments and Boson's CCNA Simulator. But for current CCNA most of stuff can be practiced on GNS. But still getting some hands on with real equipment will be an added advantage.

Here is link to another subnetting quiz tool which I found extremely helpful to get rid of my bad subnetting calculation skills:

http://www.nybi.org/subnet-2.php

Apart from this I would suggest you to join some instructor lead class in-case you have enough money to spend on it to gain hands on experience with real equipments.

But there are certain things which I would like to suggest you before joining instructor lead classes.

1. How many CCNA students have passed so far from them. Try to get in touch with someone among those and take feedback.

2. Do they have enough equipments so that you don't need to sit and wait for too long to wait for your turn to practice on real equipments.

3. The equipments they have are able to run all IOS command set and features which you need to practice for CCNA.

I have heard about many CCNA institutes which have old equipments that can't run features like SDM, No Wireless Equipments to practice wireless section, Old routers and IOS which cannot run IPv6 etc.

4. Read from books about basics of networking and ask for a demo class session to see if you and instructor have good understanding.

Just don't go blank to attend any certification class...that's the tip of the day.

Remember that practice is the key. But make sure you are good enough with theory before getting into lab and practice stuff.

Also don't under estimate CCNA exam like many other who claims it's an easy one to pass. From my personal experience I can tell you that It's not an easy exam to pass.

Also make sure you test all theory you read using equipments or GNS to make sure there is no gap. One common mistake I have seen people making while learning Cisco (including me) is that some times we take things on little grant and assumes what's written in book can't be wrong. Also it depends upon how you inter prate Author's wording. It might look to you that particular thing is gonna work one way while author was trying to tell it's gonna work in that particular way under particular conditions.

Also in case you have any CCNA queries you can always come back to me and I'll try to help you guys with those in best way I can. But there is another forum forum where you can post your queries and to get help.

www.ieoc.com

All you need to do is to create a free login and post your queries on forum.

So best of luck with your CCENT and CCNA study guys... Enjoy every moment of learning.

RIP Configuration Mock Lab - Final Version Completed

Today I proudly announce Completion of my RIP Mock Lab. It was part of an effort to bring free knowledge to people who can't afford to buy costly CCIE Lab preparation material. I started off this effort around 2 years back as an independent Technical blogger and will continue with that as long as possible.

But it's definitely not an effort against any CCIE Vendor. I truly respect them and their work. It's just my effort to bring something for people from developing countries like India where salaries don't match with Global Standards which makes life pretty tough in-case someone want to go for CCIE.

Hopefully every blog reader will like and Enjoy it. Here is the quick URL for download Lab - Tasks, Diagrams, GNS Topology for Windows & Initials.

RIP Challenge 1 - Solve The Puzzle

So here we are with another Challenge 1 for this week. I am sure that coming up with 2 exiting challenges is not a bad idea either. Anyways...Let's talk about RIP challenge as most of the networks guys (specially experienced ones) gonna say...."ehhh.....that should be simple" coz it's RIP. RIP...hmmm....RIP is very simple and straight forward kind of stuff...at least that's what most of people think.


Anyways let's me show the RIP diagram with all details and the requirement to full fill :-)

Requirements: My Favorite Part :-) 
1. The RIP Updates from R1 over network 12.12.12.0/24 
    should not be send as "Multicast" or "Broadcast" packets. 


2. Establish Full Connectivity/reachability among 
    loopback interfaces of all three routers.


Restrictions:
1. "neighbor" command shouldn't be used anywhere.
2.  Redistribution is not allowed anywhere.
3.  PBR, Static Routing, Default Routing, Tunnels are not allowed.


Best Of Luck...

Frame-Relay Challenge 1 - Solution

So the time has come when I am gonna reveal the solution for this post. I got lots of solution configs over my email. But without going further, go ahead and match your configs with my solution (Which I believe meets the requirements). In-case someone feels that my solution is not correct or something, please go ahead and send email with explanations.

Now talking back about the solution. First I would like to share my strategy about my approach to solve this FR puzzle. My idea here is to break the scenario in tiny parts and for this purpose I took a Piece of paper and made a chart to see what are restrictions and how to overcome those restrictions in best possible way.

So here is how my chart looked alike:

Now by looking at this chart you should have basic idea about how to solve this puzzle.


Here is a step by step config of each router.

So now at this point we have basic L2 connectivity to all other peer routers.


Now lets see if we can ping our own interfaces, which will accomplish the requirement of full reachability including reachability to self interfaces.


lets hop on to R3 and first ping peer routers to verify basic L2 connectivity:

So we can reach the peer routers but can't ping our own interface. "Debug Frame-Relay packet" gives us a great clue here that L3 to L2 resolution is not occurring for local interface. Here is a quick way to fix this:

Now by repeating same process i.e. putting map for local ip with local dlci, we can achieve full reachability over Router R1, R2 and R3.


But what about R4 ?


Lets hop on to R4 and see if it can ping it's own IP address without adding more config:

And magically R4 can ping it's own ip address without adding more config. But why is that?


Hmmm.... that's because it's a FR P2P sub-interface which is same as a back to back P2P connections between routers. It doesn't require any manual L3 to L2 resolution.


Now lets verify last part, if traffic destined from R2 towards R4 transit through R1:

And sure enough it is :-)

And there is one more FR challenge underway :-)
