CCIE Bootcamp - First Two Days

First two days of my CCIE bootcamp have been pretty good. David Smith, with INE, is great and he is very passionate about the topics. Dave's teaching style makes it super simple to stay focused and engaged. He has some great soap-box style rants and loves to points out screw-ups in IOS. I love it!

Day one (Monday) was focused on lab strategy and the blueprint. Its a nice light day with just a couple "soft ball" examples to get the brain going.

Day two was DMVPN, PPP and OSPF. DMVPN didn't get too deep, just the basics of getting single hub DMVPN up and going and some of the gotchas within the technology. The rest of DMVPN along with IPSec will be covered in more depth later in the camp.

PPP was, welll...PPP. I hate PPP and its one of those topics I have to suck it up and get comfortable with.

OSPF was primarily focused on single area but we did cover some multi-area and some crazy corner cases with virtual-links. This topic did start to get intense quickly!

I now know unnumbered interfaces can screw your day up pretty quick, if you dont watch out. This was proven multiple times with OSPF, PPP and even jacking up a single point of redistribution lab between OSPF and EIGRP.

Dave, your unnumbered link in the lab is the Devil!

Another topic that hit me from the side today was OSPF transit capability. Since this is an INE bootcamp here is a link to their blog which covers this topic.

Understanding OSPF Transit Capability

The general gist is OSPF ABRs have the option to choose a shorter non-backbone area route to a destination over a backbone area route (area 0). I was always under the impression it would use the backbone route every time due to intra-area routes always being preferred over inter-area routes.

For the most part I feel pretty good and am not getting overwhelmed. I am picking up some great knowledge and we will see how I do once this bootcamp progresses in more advanced topics.
