The Blueprint: (*,G) (S,G)…Multicast and IPv6

Taken with my iPhone while in NYC. iPad2's were out of stock!

Just doing a short blog entry..

This weekend I started on my second pass of Multicast and IPv6. I didn’t spend much time on IPv6…I feel that I am quite solid on this topic at this point. Not really going to speak much on IPv6 ( I may do a separate blog entry for that topic). Get solid on the IPv4 addressing (link-local, ULA, global unicast, EUI-64)and configuration. IPv6 should come naturally from a routing protocol perspective. RIPng, EIGRPv6 and OSPFv3 are similar to its IPv4 older sister. Get used to configuring these protocols at the interface level. If you don’t believe me get your hands on a Nexus switch running NX-OS. It is quite painful to work with NX-OS and then have to go back to IOS. The IGP routing protocols have moved towards interface level configuration. I like the NS-OS. They have a TONS of nice IOS enhancements that we all wish were there with Cisco IOS. Lots of  “/” notation…no more….just do 1.1.1./24 in your interface configuration!

I did review the Multicast IPv6 portions of the material. There is a good chance that IPv6 PIM BSR might show up on the lab (that’s not a much of news to anyone studying for the CCIE lab because ANYTHING could show up on the exam).

For the most part, I watched the following Multicast INE CoD Videos:

Advanced technologies COD – Multicast Module 7 (7 videos)
Deep Dive – Multicast (20 videos)

In total, I watched 27 videos. The lengths of videos ranged from 30-60 minutes per video. This curriculum was considered as a 3 Day multicast Boot camp. I took me all of Saturday and most of Sunday to get through all the videos. I watched the videos and worked through some of the corresponding labs in Workbook VOL 1. The videos were actually pretty good…Brian McGahan was the trainer for these.

Trouble-shooting Multicast can be quite involved. I plan to do more review on some of the material for the next few days to make sure I am solid by working the remaining VOL 1 labs to fill in any gaps.

Some quick  commands for me to remember(if I type them, I will remember them in the future)

ip pim send-rp-announce (for AutoRPconfigure this on the candidate RP)
ip pim send-rp-discovery (for AutoRPconfigure this on the mapping agent)
ip pim rp-address (defines the RP)
ip pm sparse-mode
ip pim dense-mode
ip pim sparse-dense-mode
ip pim nbma-mode (for non broadcast multiaccess interfaces)
sh ip pim neighbor
sh ip pim interface
sh ip pim rp mapping
sh ip mroute
ip mroute (for configuring a static multicast route)

That’s it for now…thanks for reading. SUBSCRIBE!

The Blueprint: I got BEEF with INE!

Okay…so I’ve been watching some training videos for a few weeks now to gain/maintain some clarity on some of the “Advanced Topics”

I’ll be honest…I am quite disappointed with some of the videos in the CCIE R&S Advanced Technologies Class on Demand. I’m not sure that I’m disappointed in the actual content. I’m more disappointed in the delivery with some of the training content. I’ll start of by saying that hands down Anthony Sequeira is the BEST of them all. I wish he did all of the training modules in the CoD Advanced Technologies R&S series. I’d be a CCIE in no time if he lead all the training.

Here are a few reasons why:

1. He speaks VERY clearly.
2. His understandings of the topics are superb.
3. He gives real examples and explains all the details with ease (it almost seems like he is reading your mind and focuses on the challenging topics)
4. He voice is dynamic and holds your attention…not stale and mono-tone.

My BEEF with the rest of the trainers is totally opposite of what I just described above.

Here’s why:

1. One guy sounded like he was eating or salivating while talking (smacking his lips all in the microphone). This was very annoying to me because I watch/listen the videos with my Beats by Dre. headphones on and it picks up all the nasty sounds from his mouth.  VERY ANNOYING and NASTY.
2. Some of the trainers make many mistakes while going though some of the configurations. It’s quite annoying to hear something and then have the trainer say, “forget what I just said”
3. Some of the trainers are not narrating or explaining much while they are typing commands. It’s like they are just typing commands like nobody’s watching them.
4. Some seemed to have not really thought about chronology. The order of explanations seems very poor.

Those are just a few of my gripes. I found myself just trying to find and listen to only the modules that Anthony narrated. He is such a good trainer that after I listen to one of his modules, I come out of it with a much better understanding that I ever did reading on my own. His technique and style of explaining topics and technologies is superb. Out of all the topics, I PRAYED that he narrated the QoS topic…and my prayers came true. I found myself in much better shape with QoS than I ever was after listening to that module (Module 9)

I simply wish he did all of them.

As far as my study goes, I feel that I’m a tad bit behind. I’m planning on taking a Mock Lab on May 28th to gauge where I am at. The rest of the month im thinking I will go like this:

– Do a Mock Lab within the next 10 days. (goal to make sure I am solid on CORE technologies)
– Looking to focus much more efforts on the QoS topics.
– Focus more time on MPLS
– Dive into Multicast again
– Dive into more of the non-core stuff (Security, NAT, IOS Firewall, AAA, IP Services)
