CCIE Service Provider Written and Lab Blueprint MindMaps (Freemind)

After reading this thread on on techexams.net regarding mind maps by CCIE15672. I’ve done up the CCIE Service provider written and lab blueprints in FreeMind to use a basis for study notes and to map my progress. I haven’t used mind maps for study previously, but has there is a set framework for the CCIE, I’m giving it a try this time.

I’ll upload the basic mindmaps for both blueprints shortly, for anyone who wants to also try mindmaps for study.

*Edit WP doesn’t like the *.mm extension for freemind files as attachments, work around soonish. Will also update for the INE SP Extended Lab Blueprint.

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.

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)

Cisco News: Cisco and Pearson VUE Launch Global Test Delivery Exam Security Enhancements

Ok hopefully this is true with what’s to be implemented with the Computer Based exams. I don’t think many people out there are impressed, when someone posts their perfect exam score and the fact it only took them 5 minutes to complete a 50 question based exam.

Let’s also hope that questions on the exams are also more to the point regarding the technology and knowledge required for the certification, rather than vague, full of double negatives like some certification questions.

IPv6 Special Prefixes

Some of us may have a few IPv6 references, however if they’ve been around for longer than say 2006, especially some books, then some of the specific ranges, and some ‘addressing layers’ have become obsolete, and you might not be aware. IPv6 is still in a state of flux with addresses formatting.

Specific IPv6 current address ranges of note that are still current:

Link Local Range

  • ::/128 – An unspecified address for software use only.
  • ::1/128 – localhost loopback address (IPv4 equivalent 127.0.0.1).
  • fe80::/10 – link local addresses to be used between hosts on the same link, IPv6 services, and routing protocols will be making use of this, instead of 224.0.0.0/24 with a TTL of 1). Also will replace the IPv4 LinkLocal/ZeroConf range of 169.0.0.0

Site Local Range

  • fc00::/7 – Unique Local addressing, not routable in the global address space. Used for private IPv6 and VPNs

Multicast Range

  • ff00::/8 – Range for Multicast traffic.

IPv4 Usage/Tunneling Transport Range

  • ::ffff:0:0/96 – used to map IPv4 addresses within the IPv6 routing table
  • 2001:0000::/32 - used for Host to Host/Teredo Tunneling, encapsulating IPv6 packets within IPv4 UDP datagrams. Usefull for when traversing infrastructure where IPv6 support may not exist.
  • 2002::/16Used for 6 to 4 tunneling methods, usually each IPv6 network will be attached with atleast one IPv4 network.

Documentation Range

  • 2001:db8::/32 – This range is was reserved specifically for the use within documentation examples.

Deprecated/Abandoned Ranges

  • ::/96 – zero prefix used for IPv4 compatibility
  • fec0::/10Site local prefixed intended to replace private address ranges in IPv4, has been replaced with fc00::/7 Unique Local Address range
