Study notes for the Cisco CCNP exam
Earlier I gave a description of OSPF special areas (stubby, not so stubby, totally stubby). Here’s some examples to back it up.
I use dynagen to simulate my environment, it’s so good I ended up selling my routers! Here’s the config:
autostart = false
[localhost]
[[7200]]

Every so often I get a comment or email from someone working on their CCNP which is great. I thought I’d post an update on where I am.
My CCNP expired a couple of years ago. I started this website so that I could post my study notes for the recert exam and hopefully [...]
I’ve been doing some prep for BSCI lately and am back into OSPF. One thing I ran into was keeping the various types of areas straight, and remembering all the restrictions that come with them. It wasn’t helped by an unclear description I read in the book, which caused me to really get [...]
I got a chance to look at the new CCNA Video Mentor (CVM) by Wendell Odom. It’s a 2 hour Video on CD (all Flash videos) on a variety of topics that’s meant to go alongside the
CCNA Official Exam Certification Library (Exam #640-801), 2nd Edition. The videos are really worked through labs to [...]
Often network folk have to make quick estimates without benefit of calculators, measuring tapes, or other handy things. I was thinking about this the other day, and thought I’d post some of the techniques I use.
- I’m 6′ tall, so my armspan is about 6′. Great for measuring the length of cables
- One [...]
I just got back from passing 642-811. Even though I ended up with a 962 the number of questions that I thought “I think that’s the right answer” would have made me think my score would have been lower (though as I go back and check, it looks like I was right on most)
Compared [...]

Implementation of multicast, at least for the purposes of the CCNP BCMSN exam, is pretty simple. Cisco has the Multicast Quick-Start Configuration Guide which goes over many different ways of doing it.
The exam seems to only care about Protocol Independent Multicast (PIM), which uses the router’s routing table to determine whether or not a [...]
I labbed up some Multicast stuff a while ago and only now am sitting down to write it. I’d like to write BCMSN by the end of the month because I’m taking two weeks off at the beginning of August where I won’t be near the Internet (or my routers) too often.
What is multicast?
Multicast [...]
Just a note while I come up for air…
On most switches with a hardware priority queue (egress expedite queue) like the 3550, it’s statically assigned to queue 4 (on switches with 4 queues). Some switches like the 4500s let you switch the queue, but generally it’s on silicon so you’re stuck. No problem.
However, [...]
