OSPF Notes

I got my OSPF notes thrown into a word document today.  Between taking a few pages worth of notes per chapter, re-writing the notes onto flash/note cards, and putting all the notes into word documents, I think I’m able to retain the information a little bit better.

 I wanted to print out the mindmaps from itleak, but the office LJ is broken and I don’t have a printer at home.  I suppose I’ll print them next week. 

The game plan for the next week or so is to re-read a chapter a night and take as many notes as I can handle.  I’ll do my notecards and word docs and hit practice tests every day to see how I’m progressing.

I’m giong to try and get my lab equipment back this next week.  It means that I may have to start hosting study groups at the apartment, but if it gives me more labtime with my gear, then I guess it’s worth it.  I’m trying to sell off a handful of WIC-1DSU-T1 cards right now, too.  my frame switch has a ton of db60 serial ports, and the T1 WICs aren’t any good for that.  The problem has been trying to find someone who will give me a good trade in/purchase value for the T1 stuff.

Progress

I’ve been studying off and on for BSCI all year.  I was hoping to have the exam out of the way by August, and never got there.  While working at Option One Mortgage’s DR facility, I spent most of the days trying to study and playing freecell.  Here I am in November and I still haven’t taken the exam. 

I did hit a milestone last night.  I finished the Third Edition Self-Study Guide from Cisco Press.  I haven’t been doing a whole lot of labs, as my lab hardware has been sitting in a friend’s dining room.  I spend about 5 hours a week at his place working on his CCNA.  I may need to pick my rack up this week so I can start running through the labs. 

I understand the topics pretty well.  I can look at configs, understand what’s going on, and why things are the way they are.  My issue with all of the practice tests has been configuration snipets here and there. 

I finish up with my Bachelor of Science Program at UofP next week, so that’ll give me a bit more time each week to study.  I’m going to run through the self-study guide one more time in the next month as well as the Exam Certification Guide and take the exam by the end of December.

I’m already pretty comfortable with EIGRP concepts and functionality because my previous two jobs were EIGRP shops.  I’m struggling with OSPF LSA types and the modes of operation for each layer 2 technology.  I’ve taken pretty thorough notes on it.  I just need to study them.

I need to go back and take better notes on IS-IS, route redistribution, BGP, and multicast.  I think I can handle that in a month.

BSCI specifics as recommended on groupstudy

Joseph Brunner (CCIE#19366) Posted a specific list of stuff to know for BSCI 901 this summer.  Since groupstudy’s search feature is broken, I have to manually sift though links everytime I want to find it from a different computer. 

 His post at http://www.groupstudy.com/archives/cisco/200707/msg01137.html lists the following as stuff to know:

Do not attempt the exam until you are quite familiar with

1. auto summarization
2. manual summarization for EIGRP, OSPF, ISIS
3. the difference and similarities of a ISIS Pseudonode and an OSPF DR/BDR
4. What is an OSPF LSA-2 ? Who creates it ? Where can it exist?
5. What is an OSPF LSA-4 ? Who creates it? where can it exist?
6. What is an OSPF LSA-7 ? Who creates it? where can it exist?
7. What is bgp sync ? what are some ways of preventing non-bgp enabled
routers from dropping traffic between bgp enabled routers?
8. What are some igp redistribution gotchas? How can you prevent routing
protocol feedback?
9. what are some issues with redistributing ibgp into your IGP? IGP into
Ibgp?
10. what is a bgp route-reflector? What will a route-reflector do with
routes learned from non-client peers?
11. what is a bgp cluster id?
12. what is a bgp confederation ?
13. Given a sample diagram of a ibgp network where would you recommend the
use of route reflectors? of confederations ?
14. what are some issues with the BGP next hop address between ebgp/ibgp
peers?
15. what attributes are used to select best routes in bgp for advertisement
to neighbors?
16. what are some issues with rip v2 that can effect classless address
usage, i.e. vlsm?
17. what is an isis net address? how is it structured?
18. what are ipv6 global unicast, link local, site local addresses? Where is
each used?
19. what are some common multicast addresses used by routing protocols at
layer 3? at layer 2?
20. what limitations exist for 224.0.0.0/24?
21. if my autonomous system number was 22343 what would my glop addressing
be ? 233.x.x.0/24?
22. what is pim sparse mode, where it is used?
23. what is pim dense mode, where is it used?
24. when would I want to use pim sparse-dense mode?
25. how are rendezvous points learned by pim enabled routes in sparse  mode?
26. what are candidate rp messages? who sources them? who tells other
routers an rp for a specific group can be reached at x.x.x.x ?
27. what is the pim rpf check?

I think the following is the best method for defeating all ccnp tests…

1. print the exam blueprint at http://www.cisco.com/go/ccnp
2. read the study guide from cisco press
3. read the q&a from the start of each chapter and the answers section at the end at least 5 times (yes I mean this, trust me). read more times over a longer period if you cant answer all my questions from above without looking
at the book.
4. configure some routers, if you still need help or something is amiss.
5. go back to the blueprint, create a mini-lab based on what you are weak with. Obviously if you built a large network with rip, you can probably skip this exercise for that topic.
6. create your own quick card-study guide…. one page (at least) should have all the types of bsci addressing, and conversion tacticts
-multicast layer 3 to layer 2
-glop addressing
-isis net addressing & net addressing using IP4 address
-IPv6 addressing
7. create a page of the quick card with your own favorite, hard to remember
commands
8. make and use flash cards, I did! my favorites were
for BGP, well-known mandatory, well-know discretionary, optional transitive,
optional non-transitive.
9.in your labs, do lots, and lots of debugs- It really makes sense to get in
the hang of the “protocol mechanics” now.
10. log your debugs to buffer “logg buff 65536”. print out your most complex
logs, or save them to folders on your pc. print and review often, during
lunch, after work. highlight any areas you dont fully understand. go back
through your notes and figure out how the protocol works. compare your
debugs to the configuration options.

You will be a CCNP, and you will be a solid engineer for having took the
time to develop your skills with the routers, and your thinking skills.

My first post here

I created this blog to keep track of my Cisco studies.  I have a personal blog on Livejournal, but I have very few friends over there who are into techie babble. 

 I’ve been watching a few CCIE candidates on wordpress, and figured I would start my own for CCNP and hopefully CCIE studies. 

 I may also use this to post goings on at work, and such.  I work in a Foundry shop, so working on Cisco stuff is purely a personal goal/project at this point.
