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 :



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 



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 :



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


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.








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.





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.

Free INE CCNP Workbook

Just got this URL today at IEOC.COM where Brian McGahan has provided download URL to INE CCNP Workbook. Though it was written for CCNP Ver 5. But contents are still relavant for current Route and Switch exams.

MPLS VPN Troubleshooting - Bob Calling For Help !!!

Finally after a long gap I am back with my tutorials and labs for learning and fun. Few weeks back I posted MPLS VPN Lab topology, So before explaining it step by step I thought to bring it as challenge for people who already know MPLS from R&S lab prospective and are looking for some troubleshooting stuff on it. So I am going to bring today a MPLS VPN TS challenge for them.

So our old friend BOB was sitting free on monday after noon and then he received an email containing the following topology and two fault tickets.




The topology has got two different MPLS VPNs. One is VPN blue and another is VPN red. VPN blue site 1 should be able to reach VPN blue site 2 and vice versa and same case with VPN RED. But both VPNs shouldn't be able to talk to each other.


Below is the link to download initials for lab along with GNS topology and IOS version details to run it. See if you can help BOB with this problem.


BTW.... Avoid removing configurations completely. Also being a excellent engineer, don't use "sh run" to show your skills.

Difference Between Routing Table & RIB (Routing Information Base) - Short Post



It's been long time since I wanted to talk over my blog about this. I have seen many people and books claiming that RIB is just another name of I should say fancy term to describe our old friend Routing Table. But In my personal opinion there is a significant difference between both.


RIB or Routing Information Base is local view about information from Routing Protocol Prospective. For example each routing protocol including BGP generates BGPtables in General. Yeah I know there are some more details as far how BGP builds its BGP Table :-). But for now lets talk about BGP table in short.


BGP table is local view of routing information received and generated locally. If you have ever run BGP than you must be aware about situations where you find some routing information which is in BGP table but when you run "show ip route" command , you don't see this information there. 


There are many possible reason for that in BGP like "Un-Reachable Next Hop" Address.


So what actually we see with "show ip bgp" is RIB built by BGP. On the other hand what we see with "show ip route" is Routing table which is derived from that RIB information. Or in other words best and valid information picked by router from BGP Table and placed it into routing table.




so next idea comes into mind is that how we check RIB for each protocol ?


And here is answer :-)


RIP -  "sh ip rip database"


OSPF - Older way > "sh ip ospf database"
              Modern Way > "sh ip ospf rib detail"


EIGRP - "sh ip eigrp topology all-links"


BGP - "sh ip bgp"


IS-IS - "sh isis database"


With the "sh ip eigrp topology all-links" command you can actually see routes that failed the feasibility check.


Also one of the reason that support idea of RIB being different from Routing Table is - In OSPF for example if Forwarding Address (FA) for LSA 5 is not reachable, in such case you will see entries for those LSAs in "OSPF database" with command " sh ip ospf database" but on the other hand you won't find those routes in Routing table when you run command "sh ip route"

OSPF Mock Lab 1 - Finally Out

Click Image To Enlarge


As I promised earlier, Finally the I am proud to announce about release of OSPF Mock Lab-1 & Trust me it's not going to be easy one :-)

But on the other hand I won't be able to work on any more Protocol Based Mock lab until I pass my R&S Lab which is scheduled for April End 2011. Reason being is that developing such material takes significant time. The OSPF mock lab was supposed to come out in two parts with around 25-30 Tasks each. But you guys must wait for OSPF Mock Lab 2 now. 

But still I am trying my best to bring entertainment for all readers in terms of learning.

With that being said, here is quick link for downloading list of tasks file. Again I would suggest to use Foxit Acrobat reader incase you guys can't see it properly in Adobe Acrobat reader. The password for PDF file is again - deepakarora

http://www.4shared.com/document/aMZ5tu_-/OSPF_Mock_Lab_1_-_List_of_Task.html 

Logical topology you can see above. For GNS physical topology refer the diagram:

https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiKPI1WpViLsaY4fnQLtJLbx-85B5G2cwEEGPP5_YF2J-6Wak-C1ksZtSabWH0eK3CmV4Iqm7wVRnSoYBIP4nR6zYXIJx5MfCqdSJ_wu142sQR7SotHN8E39_aCHDVpumwxcJfgY9cnOyY/s1600/OSPF+Mock+Lab+Topology.png

Here is the quick link to download initial configuration file that you would need for each router. Also I added some troubleshooting. So watch out for that :-)

As your OSPF peerings may not come up easily. For getting solution for any of tasks send me an email at - deepakarora.1984@gmail.com with your comments about Blog and Mock Labs.

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.

OR 

http://hotfile.com/dl/76776402/93ff2ff/RIP_Mock_Lab_-_By_Deepak_Arora.rar.html 
  
However for Solution Guide, I would request you spend little time to write an email to me (@ - deepakarora.1984@gmail.com) with your comments on RIP mock lab and about my blog and efforts (Good or bad).

All files are in secure pdf format with password as - deepakarora (same password for RAR file). Make sure you guys use Primo PDF Viewer software(http://www.primopdf.com/download.aspx)  to open pdf file to avoid any format issue which you may have with Adobe pdf Reader.
