CCIE link #12

This post is by Brian McGahan on OSPF type 5 E1 vs E2 routes. It explains in detail how the OSPF state machine works and busts a few myths on OSPF metric calculation. Remember that OSPF prefers E1 over E2 regardless of metric. A common misconception is that E2 does not use cost to ASBR when calculating metric. Read the post to understand why this is wrong.

To be a CCIE we need a good grasp of switching and STP. This post by Petr Lapukhov (again) is one of the best I’ve ever seen on STP. This post describes PVST+ in detail. Read it here.

This is the final post by Petr on route redistribution. If you have read all three of them you should have a much better understanding of route redistribution. Also, INE has released a few videos on route redistribution from ther ATC. These videos are very good and I recommend you watch them.

This is Petr from INEs second blog post on route redistribution in a three part series. I am starting to get a better grasp of route redistribution. I want to reach the level where I can look at a diagram and immediately identify potential loops and problems and think about what measures to take to prevent problems. If Cisco says I can’t use feature X or Y I should know how to do it using feature Z. So here is part second part in the route redistribution series.

Route redistribution can be very complex in certain scenarios. I have struggled a bit with some of these scenarios and now I’m trying to increase my knowledge in this area. This post at INE is by Petr Lapukhov. Petr is probably one if not the smartest guy out there with multiple CCIE’s and a CCDE. This post from him is about redistribution, this is the first part in a three part series. I highly recommend you visit it.

I haven’t really had the time to do a daily post with CCIE links so from now on I will just call them CCIE links. This link is to a fellow blogger who did a post on OSPF. OSPF might be the most important protocol to know on the lab but certainly in real life. This post describes how to interpret the OSPF database.

CCIE link of the day # 6 – Use the community

Many of you will have heard about Groupstudy. Groupstudy runs a few mailing lists for different levels of Cisco certifications, you should join the CCIE one. This requires that you have already passed the written. You should join it for a couple of reasons.

  • There are a lot of experts and people that have passed the CCIE
  • You can learn by reading other candidates questions
  • You learn by asking your own questions
  • There is an archive with earlier mails

Definately use Groupstudy as one of your study tools for the CCIE.
