The CCIE R&S Journey

I decided on aiming for the CCIE R&S shortly after completing my CCxP exams in 2006/07, however had the initial thought, while doing my CCNA way back in 2003. Basically I found while doing my CCNP studies, despite being an enriching and enjoyable experience (labbing, reading, applying in the real world), not many people were all that interested or not willing to differentiate between a CCNP or CCNA when it came to job responsibilities and remuneration. Perhaps this is because they may have been burnt by someone who may have taken ’shortcuts’ or not quite what they claimed to be.
I’ll admit I’ve met some people like this myself, and it is a little disheartening, when you’ve put in a lot of effort. Yes, they don’t last long and are found out rather quickly, but it was seriously getting time to separate the wheat from the chaff.

I had completed my R&S written exam (350-001) in the middle of May 2008. I mainly used most of the Tech Library I had built up over the years of Cisco Press and O’Reilly books (including Routing TCP/IP Vol 1 & 2), as well as the CCIE Routing and Switching Exam Certification Guide 3.0 recently updated. The written didn’t contain anything too difficult or unseen before, while doing my previous certifications or on the job experience. The amount of questions did press me for time; I wouldn’t expect anyone to fly through these, regardless of the difficulty.

From here, I spent the next 9 months preparing for the Lab, going through a popular vendor’s workbooks and video/audio classes to practice out configurations, blueprint topic technology behaviour (this includes the caveats), and completing tasks under pressure. I think most other CCIEs have all been here, therefore wont expand on this.

It took me two lab attempts to get over the line, which I’m rather happy with, as I’ve read some horror stories about some candidates getting into 6+ attempts. Both of my labs were fairly straight forward with what they asked for, and to be honest there was nothing difficult about them, as you really should be familiar with the CORE of the blue print topics (L2 Switching and FR topics, IGPs and EGPs), and know where to find everything else in the DOC-CD. Based off my first attempt result, I felt I only missed out but a few points, by violating a requirement, as I was able to verify 90% of my configurations. After getting my first result, I wasn’t crushed, but more psyched up to get back to the LAB again :-). I can see why you barred for 30 days before able to attempt the lab exam again for the same track.

I gave myself 8 weeks off before going back, and didn’t really do much revision during this time either. I only need to keep the grey matter warm, but not burn out on 24 hour revision or labing, as I had already done this. Plus my day to day job is 100 percent networking, so I wasn’t completely cold.

Day of the second attempt arrives; I’m back at the lab, powering my way through the tasks getting the important tasks out of the way by lunch time. This gives the remainder of the day, to verify and nut out the remainder tasks with the DocCD. I left feeling pretty confident this time round.

The following day I get my score report and the all important numbers!! PARTY TIME! Just as well, with the CCIE R&S 4.0 change announcement at the time.
For those wondering… I did have to do the Open Ended Questions format during each attempt. My advice to those still panicking about them is to not worry ‘too much’. They are simple and I’d expect a CCIE candidate to be able to answer them, you MAY get a curve ball in the batch though, so prepare for it.

I’m now deciding where to go from here, as CCIE Security and Service Provider do interest me, but I’m not sure if I want to commit the same amount of time I did with R&S on another CCIE, as I DO WANT A SOCIAL LIFE!! I may just go back to learning networking tech that just interests me at a slower place, without sticking to a blueprint or exam topic list.

I for one welcome our new overlords of normality :)

CCIE R&S Completed!

Just a brief update to state I completed the CCIE R&S lab sucessfully a little over a week ago. Too busy enjoying life at the moment to post a lengthy experience post… I promise there’ll be one shortly.

Random Update

Yes I’m still alive and still battling for the CCIE. Hoping to have it done before the changes come in for CCIE 4.0.

I do like what’s on offer for the new 4.0 changes with the troubleshooting sections being introduced.

RFC1925 The Twelve Networking Truths

The Fundamental Truths

(1) It Has To Work.

(2) No matter how hard you push and no matter what the priority,
you can't increase the speed of light.

(2a) (corollary). No matter how hard you try, you can't make a
baby in much less than 9 months. Trying to speed this up
*might* make it slower, but it won't make it happen any
quicker.

(3) With sufficient thrust, pigs fly just fine. However, this is
not necessarily a good idea. It is hard to be sure where they
are going to land, and it could be dangerous sitting under them
as they fly overhead.

(4) Some things in life can never be fully appreciated nor
understood unless experienced firsthand. Some things in
networking can never be fully understood by someone who neither
builds commercial networking equipment nor runs an operational
network.

(5) It is always possible to aglutenate multiple separate problems
into a single complex interdependent solution. In most cases
this is a bad idea.

(6) It is easier to move a problem around (for example, by moving
the problem to a different part of the overall network
architecture) than it is to solve it.

(6a) (corollary). It is always possible to add another level of
indirection.

(7) It is always something

(7a) (corollary). Good, Fast, Cheap: Pick any two (you can't
have all three).

(8) It is more complicated than you think.

(9) For all resources, whatever it is, you need more.

(9a) (corollary) Every networking problem always takes longer to
solve than it seems like it should.

(10) One size never fits all.

(11) Every old idea will be proposed again with a different name and
a different presentation, regardless of whether it works.

(11a) (corollary). See rule 6a.

(12) In protocol design, perfection has been reached not when there
is nothing left to add, but when there is nothing left to take
away.

Basic Multicast AutoRP and BSR setup v0.1

AutoRP

All Participating Multicast Routers
ip multicast-routing

either:

Router(config-if)#ip pim sparse-dense mode

OR

Router(config)#ip pim autorp listener
Router(config-if)#ip pim sparse mode

*AutoRP relies on dense mode for RP and Mapping Agent communication, therefore if sparse mode is configured on an interface, then ip pim autorp listener needs to be configured to enable dense mode flooding for 224.0.1.39 and 224.0.1.40

Candidate RP:
Router(config)#ip pim send-rp-announce (interface or ip address)
Router(config)#ip pim rp-announce filter rp-list (access-list unicast) group-list (access-list multicast)

RP Relay Agent:
Router(config)#ip pim send-rp-discovery (interface or ip address)

BSR (utilised PIM v2)
All Participating Multicast Routers, including RP and BSR routers
:
Router(config)#ip multicast-routing
Router(config-if)#ip pim sparse-mode

RP and BSR routers only:
Router(config)#ip pim bsr-candidate (interface)
Router(config)#ip pim rp-candidate (interface)

Juniper: Juniper Networks Certification Fast Track Program

If you’re looking at an alternative to Cisco certifications, or looking at expanding your horizons like all good networkers should. You should check out the Juniper fast track program, and take up some of the discounted offers on Juniper Certifications for the Enterprise tracks, especially if you have exposure to Juniper equipment.

http://www.juniper.net/training/fasttrack/

I’ll be looking at boosting my own Juniper knowledge once I get this CCIE lab out of the way. There’s also no shortage of reference material out there on the net. Again something to look into if you are wanting to get an edge career wise.

Cisco News: Cisco Support Wiki launches

Cisco has launched their very own support wiki page found here. It’s full of how to’s and all things that should stop you from scratching your head when trying to remember how to configure a few things.

Clearly this will not be available during the CCIE Lab exams :p, so for us potentials we still need to get used to the DocCD setup… for now at least.
