Tutorial: Filtering Routes in OSPF Part 2 » Filtering Between Areas Using area filter-list

In our last article on filtering Routes in OSPF we looked at filtering routes within an OSPF area. In this article we will be filtering routes between areas using the area filter-list command. OSPF route filtering is an important concept to be familiar with for any CCIE candidate. We will be looking at the area filter-list command first. Part 3 will then look at some of the more obtuse ways of filtering using the area range and summary-address commands. Part of being a CCIE is knowing multiple ways of configuring the same task…just in case those evil proctors decide to restrict which of those methods you can and can’t do! :)

Tutorial: OSPF Network Types & Frame-Relay Series

Knowing the OSPF Network Types and how they work with different frame relay topologies is one of those things that you should know inside out if you are attempting the CCIE lab. This five part series of tutorials are designed to take you through all the different OSPF network types and demonstrate how they interact with Frame-Relay over various partial-mesh topologies.

Tutorial: OSPF Network Types and Frame Relay Part 5

In my previous tutorials we looked at the different OSPF Network types and also how they interact with each other. In this tutorial we will be looking at implementing OSPF over a partial mesh Frame-Relay network with multiple hubs and spokes. This is the last of the OSPF Network Types and Frame Relay series of articles….unless I find something cool! :)

Blog: Cisco, the new CCIE Plaques suck!

I got my CCIE plaque in the mail yesterday.To be honest, I’m really disappointed. I wish they didn’t get rid of the old ones (Greg I’m soooo jealous!). After all that hard work, this thing looks like its made out of plastic. What am I saying, it IS made out of plastic! Plastic with a bit of glass stuck on the front. Bring back the old medallions. That is something you can show of with pride! Continue reading for a photo…

Cisco Spamming Blog Comments For New Learning Portal….Nice!

They are obviously trying to get you to go to their new Cisco Learning Network Portal. This portal actually looks pretty cool. Its a web portal with a discussion forum etc. The CCIE section is pretty bare at the moment, but hopefully they put some cool tutorials or videos etc. Now I wonder how many of those comments on the forum are real….

Cisco has announced three new concentrations to the CCNA program - CCNA Security, CCNA Wireless, and CCNA Voice. Candidates at the associate level (CCNA) are often expected to operate and maintain voice, security, and wireless equipment and this program is designed for such candidates. You must have a valid CCNA to achieve these concentrations. The concentrations allow a current CCNA to specialize and serves as a stepping stone to the Professional level certifications.

Public Apology from Robert Williams, CEO of CertGuard

Robert Williams from CertGuard has issued a formal public apology to Ethan and the CCIE community. I’m glad we can now put an end to this soap opera and the rest of us can get back to studying and writing articles for the CCIE community.

Return of the Jedi…Ethan’s Back!

Ethan’s back…
Great response from the CCIE Community. I posted my take on the whole fiasco here, and I am glad if it helped in any way. In the end common sense and justice prevailed. The reputation of both NetworkWorld and CertGuard has been severely tarnished by this, and I hope CertGuard and Robert Williams are [...]

Blog: The Whole Ethan Thing….

No doubt if your a follower of the other CCIE blogs, and a regular reader of groupstudy you would have seen this whole thing about Robert Williams from CertGuard slamming Ethan Banks for cheating on his exam. CCIEPursuit summed it up nicely, as did Matt Hill, Collin McNamara, Deon Botha and Greg Ferro.

Blog: CCIE:R&S…Done…Now What?

After doing what anybody passing their CCIE does (killing brain cells with beer), I had time to reflect on what has been an awesome year so far. I’ve had emails from all around the world, calls from family and friends congratulating me. But you wouldn’t believe how many emails, and conversations I’ve had that contained the question “What are your plans next? Now what?”…

Tutorial: IPv6 Tunnels Part 2 - Automatic 6to4 Tunnels

In our previous article on IPv6 tunnels, we looked at manual GRE and IPv6IP Tunnels in order to provide connectivity for IPv6 networks segregated by an IPv4 network. By tunneling IPv6 over IP, we can migrate our internal networks to IPv6 and still have communication between these networks, even though we are seperated by an IPv4 network. In this article we will be using another method to provide connectivity for IPv6 networks segregated by an IPv4 network: The Automatic 6to4 Tunnel! Mastering IPv6 is not only an important part of a CCIE candidates journey, but will become increasingly important as the global pool of IPv4 addresses diminishes….

Accessing your console lines with Reverse SSH

Greg Ferro from My EtherealMind has a great article on IOS Reverse SSH console access. We use reverse telnet access here for all our lab equipment access and I always wondered (but never had time to investigate) whether we could do reverse ssh. Looks like I’ve just given myself more work to do. Thanks [...]

U.U.U Ping Response

Ever wonder why you get a U.U.U ping response time instead of a UUUUU for icmp unreachable messages? Well wonder no more! Packetlife has a great article dissecting the U.U.U ping response. I knew about icmp rate-limit but I never put two and two together before reading the article. Awesome!
