Blog: CCIE Assessor Lab A
I just finished my CCIE Assesor Lab A. I got 72%. I have mixed feelings about this one. The script looks for very specific answers but it gave you a fantastic insight on what Cisco is looking for in terms on configuration and how they mark your exam….

Mock Lab 6 Analysis – RIP Summary Address and Default Routes
I ran into this strange problem while doing Mock Lab 6, and I thought it warranted an article because it highlights why the order of operations that IOS performs certain tasks is important.
Blog: 23 days to go….Mock Lab 6 Done!
I finished Mock Lab 6 yesterday. I think i did better than the last mock lab. Going through the solution guide this morning, i got a few things wrong. Most of these were really stupid errors that I’m gonna blame on my brain being mush at around the 6 hour mark. 8 hours is still a killer for me to sit down in one stretch. I was reading on Slashdot the other day how scientists are using brain performance enhancing drugs…my first thought was “Where do i get some?! That would really help studying for a CCIE!” lol.
Tutorial: IPv6 Tunnels Part 1 – Manual GRE & IPv6IP Tunnels
Lets face it, sooner or later we are going to move to IPv6. Probably closer to the sooner side than some of us are comfortable with. In this series of articles we will be introducing tunnels and taking a look at how they can be used as part of you migration towards IPv6. Working with IPv6 tunnels is also an important part of a CCIE candidate’s journey, so mastering them is important. In this article we will be looking at tunnelling IPv6 over IPv4 using manual tunnels specifically using GRE and IPv6 in IPv4.
Security: Common Ethertypes in Vlan Access Maps
I was putting together my study notes on Vlan Access Maps and all the common ethertypes that I was asked to match in all the labs that I have done. I was trying to figure out how to match spanning tree BPDU’s when they are transported in Ethernet frames, and was having real difficulty locating this on the Cisco DOC CD…..
Blog: 28 days to go….A day in the life of a CCIE candidate
4:45am: Crawl out of bed. I went to bed at around 11pm last night, and couldn’t really get to sleep. My brain just wouldn’t unwind, and I kept thinking about a redistribution problem i was trying to solve. My quality of sleep has definitely gone down lately. I’ve been doing a minimum of 12 hours a day on labs, and then about an hour watching COD videos before dozing off. I think i need to take a rest day sometime soon. Maybe just watch COD videos all day, otherwise I think I will burn out.
QOS: Applying CBWFQ to a sub-interface
By default IOS does not let you apply CBWFQ directly to a sub interface. I ran into this scenario and worked my way around it in a workbook lab (IE Workbook Vol 2 – Lab 15). I thought it was pretty cool and hopefully it helps someone else out..
Multicast: What is the difference between an igmp filter and an igmp access-group?
After doing IE Mock Lab 5, and analyzing it over the last few days, I had an epiphany with regards to an igmp filtering question. The question required you to limit users joining a certain multicast group, and also place a limit on how many groups users in that vlan can join. I immediately thought “Oh cool, no problem ip igmp access-group with a standard access list, and an ip igmp limit and we are good to go! This stuff is easy”. Brrr! Wrong! :)
Blog: 40 days to go…
Well, I completed my first Mock Lab (IE Mocklab 5) last night. The Mock Lab was great and did just what I wanted it to do: push me just that little bit harder than I was used to. It definitely got me out of my comfort zone. It was rated an 8, which is supposed to be harder than the actual lab. This is a little comforting, because I didn’t do as well on it as I’d hoped.
Tutorial: What is the difference between bandwidth percent and bandwidth remaining percent?
One of the most common questions that CCIE candidates face when studying QOS MQC for the lab is “What is the difference between bandwidth percent and bandwidth remaining percent?”. Both are used in CBWFQ when implementing congestion management but what is the difference? The answer to this questions are the focus of this tutorial.
MPLS VPN Tutorial
Human Modem has published part 2 of his fantastic MPLS VPN articles. The tutorial is great if you are just starting out studying for your CCIP or just want to get started with MPLS VPN’s. Looking forward to the rest of the series!
Blog: 68 Days to Go….
After reading through the fantastic (and inspirational!) CCIE in 3 months blog I’ve decided I need to get more organised. His post on his dynamips environment contained something that literally caused me to sit up and say “now why the heck haven’t i been doing that!”. In the post is a picture of a pdf file, that he fills out after each and every lab that he completes to grade himself.
Tutorial: OSPF Network Types and Frame Relay Part 4
In our previous tutorials (you can find Part 1 here, Part 2 here and Part 3 here) we looked at the different OSPF network types and how they apply to a partial mesh Frame-Relay Hub and spoke topology. In normal situations that would be enough, but this is the CCIE we are preparing for! We have to understand how the different network types work together. This is incase the proctor decides to not allow you to use certain types of OSPF networks on one interface or does not allow you to use the ip ospf network commands on others. Evil Proctors :)
Blog: My Favourite Net Things
I’m feeling a bit more confident about the lab. I have been working steadily through the IE workbook and things are falling into place nicely. I still need to work on my speed and accuracy but i can do the Core (Switching, Routing, BGP) sections of most of the labs within 2-3 hours. This is a big improvement for me.
Troubleshooting IP Routing Protocols Video Part 2
InformIT has posted Part 2 of the video interview with Zaheer Aziz, author of the Cisco Press title “Trouble shooting IP Routing Protocols”. Zaheer talks about learning how to solve complex IP routing problems and explore protocol-specific debugging tricks that speed up problem resolution. Check out the video here.

Tutorial: How to set up backup interfaces
The idea behind a backup interface is a simple one. If your main interface goes down, a secondary interface (like ISDN or frame) is brought up and traffic goes through this until connectivity is restored to the main interface. In this article we will be exploring how we can implement such a configuration using the Cisco IOS backup interface command.
ccieblog.com
I discovered this while reading my rss reeds. It is a CCIE Blog portal! It has all the major CCIE blogs and even has provision to set up your own CCIE blog! What a great idea! I wish something like this was around when i was first looking around for CCIE blogs! If you [...]
Tutorial: OSPF Network Types and Frame Relay Part 3
In our previous tutorials on OSPF Network types (you can read Part 1 here, and Part 2 here), we looked at the OSPF broadcast, non-broadcast, point-to-multipoint, and point-to-multipoint non-broadcast network types. In this article we will be taking a look at the last of the ospf network types, namely point-to-point and loopback network types.
Cisco Certified Design Expert (CCDE) Interview
Joe Harris from 6200network.com has a great interview with one of the people involved in developing the new Cisco Certified Design Expert (CCDE). Great information on this new Expert level track from Cisco. Check out the interview here.
Blog: CCIE Practice Lab Built
I’ve got my own practice labs! Well it’s not really mine, but work has graciously let me do my CCIE prep on the BSCI gear they have. What this means is that when a BSCI class is not running, I can use it for my CCIE lab prep. We run a BSCI class about once a month, so that means the rest of the time its mine! The BSCI kit consists of 14x 2600 routers, 1x 2522, and 1x 2950. I’ve cabled it up to mimic the Internetwork Expert Topology (minus the 4 switches!). All the 2600’s are cabled into the 2950, and the 2522 acts as an 8 port Frame-relay switch for 8 of the 2600’s.
Emulating JunOS
Himawan Nugroho has updated his awesome blog with information on how to set up JunOS on an emulator using jqemu. Awesome! Dynamips/Dynagen to study for your CCIE, Jqemu to study for your JNCIE!
Backing Up Router Configs to SharePoint
I found this great article on google blog search today: Sharepoint for Cisco fanboys. The article details how to use Sharepoint’s version control features to save multiple copies of Cisco configurations. Awesome! Looks like I’m going to be busy at work.
