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 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
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
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
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
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
8. make and use flash cards, I did! my favorites were
for BGP, well-known mandatory, well-know discretionary, optional transitive,
optional non-transitive. 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.
