The class was great, I feel like I learned so much. I will definitely be taking it again before doing the lab. Here’s the layout again:
- Day 1
- Frame Relay
- Day 2
- Day 3
- Day 4
- Day 5
The depth and coverage of all technologies were amazing. I hope I retained even 50% of everything he taught us, even with 50% of it I think I’d have a good shot at passing the lab on the first try. My favorite day was BGP and MPLS, because I can’t get enough of those. Each day was grueling and and amazing. The workbooks are the best I’ve seen so far. The explanations provided in the answers are infinitely helpful in understanding the technologies.
Yesterday was BGP and MPLS. Probably my favorite day. I really can’t get enough of those technologies. It was mostly lecture which was very deep. This was the first day that I felt like I wasn’t far behind the lecture. I knew 95% of what we were talking about and how to implement it. I was quite happy. Naturally Narbik showed me some stuff I’d never seen and gave me a new way to think about things. All in all, it was a great day.
After class (~9:30) a few of us, including Narbik, went to the hotel next door to grab some drinks. It was a good time.
Today is a short day and the technology is Multicast. This is one of my weaker subjects as I haven’t really touched it since BSCI. I’m hoping to learn and retain a lot today.
Sorry I didn’t post last night, I was dead tired. This week is tough.
Yesterday was QoS and RIP. It was mostly lecture. I feel like a gained a MUCH better understanding of Policing and Shaping yesterday, I just hope I can keep it in my brain. Learned a ton about RIP too, and the depths of routing in general. Can’t say enough good things about Narbik or this class, I would recommend it to anyone.
Today is the day I’ve been looking forward to all week, BGP and MPLS. Woot!
I should be able to throw something up midday, I hope.
Day 2 is nearly over. It’s been full of OSPF. Lots of lecture and labbing. Narbik has so much in his brain, it’s really unbelievable. Everyone knows that OSPF is very deep, but after today I’m speechless. I’ve made some tables and a diagram (from Narbik’s drawing on the whiteboard) with some of the information I want to save. Here is table of OSPF LSA Types:
It tells you which type of router sends them, what they look like in the RIB, what commands we can use to see them and some other things.
Here is the table of OSPF Network Types:
Also filled with good info.
Here is the diagram I made from his drawing on the board:
We’re still going. Around 10 hours so far (hourish lunch break, and 5-15 minutes here and there).
We’ve covered L2 stuff so far. Mostly security stuff: VLAN Hopping, Port-Security, DHCP Snooping (and Source Guard, DAI), ACLs, PVLANs, and Dot1x. Great information. Narbik is ridiculous, he writes all the commands out on the board… from memory. It’s sick.
Not a ton of lecture so far, just the L2 stuff. Mostly doing labs. Frame Relay is up next.
Class is great so far. I’m a bit sad that STP isn’t covered in much detail. That’s one of my weak points as I haven’t gone into much detail on STP since BCMSN. I asked Narbik about it and he told me there isn’t enough time to cover everything (camp is only ~4 1/2 days), I think L2 is easy for most people also, where routing is more my thing. Whaddya gonna do.
