CCIE Bootcamp - Second week

The second week of my INE 10 Day bootcamp went a lot quicker than expected. Week two though was just as intense as the first week.

Dave did a great job on Monday of breaking down MPLS VPNs and really solidified my understanding of the control and data plane within MPLS VPNs.

The first half of the week was focused on MPLS, Multcast, and IPv6. We spent a fair amount of time covering thee topics in-depth. Just like week one Dave didnt really cover the basics as that knowledge was assumed. This allowed us to focus on each topic at a deeper level. The situations we were lead into by the topology really help solidify my foundation knowledge of each topic and showed me what to watch for in the lab and what gotchas it could lead me into.

The second half of the week was covering Switching, QoS, IPSec, DMVPN and services. None of these subject were covered in as much depth as the core technologies but I feel we could have spent another two week covering them fully. These topics dont hold much weight in the blueprint anymore so Im happy we didnt spend much time on them. Time was better spent on the core topics.

Overall this camp was worth every dollar spent. I came away with a ton of new knowledge and have a good understanding of my weak areas. Now time to get my head down and get my digits.

CCIE Bootcamp - First week

Man week one went fast but there was a tons of great information we reviewed.

Wednesday was primarily OSPF and some EIGRP towards the end. Dave did a great job with breaking down the LSDB and we ran though a great situation that help solidify the changing of the Forwarding Address and the issues that can be presented.  He also built out the complete network just from LSAs. If interested Pete Lumbus also wrote a blog post that covers this in detail here. He does a great job of breaking it town and it helps a ton with understanding LSAs.

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.
