Now that we have the basic configuration out of the way and the device is manageable, the next step is configuring the ACE to load-balance for a site. Our task will be to configure the following; The configuration for the above is; I am trying to get my hands on one of our spare 6500’s […]

The configuration we will look at is an ACE module that goes into a 6500 series chassis. It would help if you did some prep work on the 6500 before configuring the ACE. The first step is to create the VLANs; in this example, we will use VLAN 4 and VLAN 67. The next step

Wow, it’s been a long time since I’ve posted. I have been knee-deep in studying for my CCIE R&S, learning my new environment at my new job, and being a father to my newborn son. I will start the New Year with something new I learned at my job: how a Cisco ACE works and

I just passed 642-611 and am now a CCIP. I will still post the MPLS blogs in my downtime while waiting for my books for CCIE Security.
LSR (TSR) stands for Label (Tag) Switched Router. This is where you can see how MPLS can work. An LSR, if it is at the network edge, can impose (Push) or dispose (POP) of a label, while the intermediate LSRs swap labels. We are going to base our discussion on the below diagram. The above
As you might have guessed, LSP stands for label-switched path, and TSP stands for tagged-switched path. As shown in the example below, this is the path your label-switched packet will take through your network. Here are a few facts on LSP/TSPs
When I started writing this blog post in Word, I thought I would throw all the MPLS acronyms into one blog post. I have realized it is way too long and would probably make your guys fall asleep, so I have decided to break it down by acronym. We are first going to look at
MPLS stands for MultiProtocol Label Switching. MPLS is a service provider technology that allows fast packet switching based on a label number instead of a MAC address. The MPLS frame sits between the Layer 2 and Layer 3 frames on an IP packet and is 32 bits long. The MPLS label looks like this. The
Over the last few months, I have been studying for the Cisco MPLS exam, and it has been a lot of fun. I already had an idea of MPLS from my ISCW study, but going into more depth and seeing how MPLS operates was a good experience. Over the next few days, I will post

I took 642-661 (Implementing BGP on Cisco Routers) and passed. This means I am one step closer to my next goal of CCIP before I attempt the big CCIE. The test was a hard test, it was what I expected, but some questions took me off guard. My study material was; Next up – 642-611 (Implementing
