Well, Cisco officially took their payment for my lab on 12.12.12 It is now time to start going crazy!
802.1 Q-in-Q Tunneling using Etherchannels
Our last post looked at Q-in-Q tunneling using one port, but what if you had to extend an EtherChannel from one data center to the other? We can also use Q-in-Q tunneling with EtherChannel. The train of thought is similar to how we did just a straight Q-in-Q tunnel, but now, with EtherChannel, we need

802.1 Q-in-Q Tunneling
802.1 Q-in-Q tunneling is a technique that can extend a VLAN from one data center to another without AToM or VPLS. Essentially, Q-in-Q tunneling adds another .1q tag to your packet as it traverses the Service Providers network. This keeps your traffic segregated from any other company, following the same principle of how VLANs segregate

Controlling RIP with Offset-Lists and Administrative Distance
This blog is coming from sunny and humid Jacksonville, Florida. Today, we will look at controlling the RIP routing domain using Offset-Lists and Administrative Distance. We must remember that RIP is a distance-vector routing protocol with no idea what the network topology looks like. With this, we can trick RIP into thinking a network is

CCIE Lab is Tentatively Scheduled
So today, I checked to see if I could schedule the lab, and I was able to. Thinking I couldn’t get the date I had in mind, I searched for it. San Jose had no open seats, but RTP had 5. I just struck gold, and it was meant to be; I registered for the

Well, I passed the CCIE R&S Written test today. It was a mixed bag for me, a lot easier than my first test two weeks ago, but my wife kept telling me tonight that a pass is a pass. For the next few days, I am working on a project file outlining how I will

CCIE 1, Mike 0
As you may tell by the blog title, I took my CCIE R&S Written test today and did not come out victorious. Without breaking any NDA’s, I just barely failed, which usually would upset me, but I know where my faults are and where I did very well. I also attempted to take a test
CCIE Notes: EIGRP
EIGRP Feature Summary EIGRP Updates Once routers are adjacent, they can exchange EIGRP update messages, which follow; EIGRP uses Reliable Transport Protocol (RTP) to send multicast EIGRP updates. EIGRP sends updates and waits for a unicast ACK reply from the neighbor the update was sent. If an ASK is not received in the Retransmission Timeout
CCIE Notes: IP Forwarding Basics
IP forwarding is how packets go from one side of the network to the other. It is also known as IP routing. So we can have a base understanding, let’s look at the diagram below. How does the R3 know how to forward the telnet packet to R1? Fast Switching and Cisco Express Forwarding (CEF)
