My CCIE Home Lab is Complete
I wanted to post this a few days ago, I have completed my CCIE home lab. The lab consists of the following devices; Here is a photo

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

Now The Fun Starts
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)

CCIE Notes: IP Services
When dealing with IP services, you deal with service elements of the IP protocol carried on the IP datagram stream. Some of the IP services we are looking at; ARP We are first going to look at ARP. ARP maps IP addresses to MAC addresses. Before a host can send data, it must do an

CCIE Notes: Etherchannels
Whether we are talking about EtherChannels or PortChannels, we are talking about the same technology. That technology is a way to allow you to treat multiple physical links as one link to Spanning-Tree, and you can also do some load-balancing on them. There are two types of port channels. They can be a layer 2

CCIE Notes: Spanning-Tree
Spanning-Tree is a layer 2 loop detection mechanism for a switched network. There are several spanning-tree standards Cisco also has two proprietary types of spanning tree; One of the most important pieces of a spanning tree is electing a root switch. You can leave the election up to chance or “rig” the election how you
