MPLS Complete
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 and TSR
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
LSP and TSP
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
LDP and TDP
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
What is MPLS?
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
