MPLS is Fun -Worklog Part I

I’m currently preparing for the MPLS test under the CCIP track. It’s the last test I need for the certification. I figured it would be fun to show everyone some of the MPLS networks I have been designing for learning purposes…

When I first started working with MPLS, I wasn’t sure how much I was going to actually like it. There are a lot of technologies in the Cisco world that I can implement well, but liking them is another story – yes, some things aren’t fun to configure (can you say ISDN?).

If anyone has started looking at the new CCNP track, you will find yourself having to learn about MPLS soon enough! I recently finished teaching the ISCW course, and there is a decent amount of MPLS on the exam. I think my excitement about MPLS sort of instilled itself into my students. I often find myself going off on a tangent sometimes, but you can never have too much MPLS!

By far, the coolest application for MPLS is the VPN technologies. Virtual routing and forwarding tables (vrf tables) are too good for words! Quite simply, MPLS VPNs take the best aspects from traditional peer-to-peer and overlay VPNs.
