This blog post provides example M-VPN configuration using out-of-band mapping of C-multicast groups to core M-LSP tunnels signaled via M-LDP. A reader is assumed to have solid knowledge of M-VPNs and understanding of M-LDP. For people unfamiliar with M-LDP, the following blog post provides some introductory reading: The long road to M-LSPs. The terminology used in this article follows the common convention of using the “P-” prefix for provider specific objects (e.g. multicas routes or tunnels) and using the “C-” prefix for the customer objects (e.g. private IP addresses). Before we begin, I would like to thank our reader Hans Verkerk who pointed me the fact that Cisco IOS does support M-LDP in the latest 12.2SR images.
To recap, M-LDP allows for construction of P2MP (point-to-multipoint) and MP2MP (multipoint-to-multipoint) LSPs. Every LSP is identified by a tuple

One of the most prominent applications of M-LSPs is effective multicast traffic encapsulation in MPLS networks. Since M-LSPs are signaled using M-LDP and multicast trees use PIM the problem is mapping multicast trees to M-LSPs. It is intuitively obvious that shortest path trees could be mapped to P2MP LSPs and shared trees correspond to MP2MP LSPs. There are two approaches to implement such mapping: the first uses in-band signaling, where PIM messages are directly translated into M-LDP FEC bindings, and the second approach uses out-of-band mapping, e.g. based on manual configuration.

Petr Lapukhov is an incredible inspiration to so many of us in the Cisco Certification space. But sometimes, when you are speaking with an individual that has never tasted failure, you begin to wonder what advice or life lessons they can provide to us “mere mortals” pursuing such lofty goals.
Well, it turns out that Petr had finally encountered a practical certification exam he could not immediately master! In fact, he failed it many times over! What exam you might ask?????
The Nevada Driver’s License Practical Skill Test!
Petr – congratulations on this incredible achievement and enjoy your new privileges.
NOTE TO STUDENTS: Please consider public transportation options when visiting the Reno, Nevada INE facilities. In fact, we recommend avoiding the various public road systems as much as possible.
Our student and friend Deepak Arora was kind enough to share these sample TSHOOT exam questions in the IEOC.Thanks again, Deepak!
Enjoy everyone. The interface is pretty self explanatory, and as you can see, Cisco is combining several previous flash-based, written exam elements into one here. If you do need assistance with it, I copied the instructions link here as well.
We are working hard on the exciting new TSHOOT course, and yes, it will be made available free of charge to all of our existing CCNP students as part of our Investment Protection Program.
Also, we will be announcing a date of release soon.
Hello INE fans!
You might have noticed we stalled new video production for the last week.
Two reasons:
1) We are busy in bootcamps around the world right now. Always good.
2) For each new video series, we wanted to incorporate all of the great feedback we received on these products. I presume that since the Advanced Technologies Series is legendary in the CCIE Training space, this helped to generate what seemed to be a mountain of opinions on the “new and improved” edition.
After meetings and much discussions on the absolute greatest new products we could create, we are now back to “shooting videos” on a daily basis. Check your accounts for new lessons appearing DAILY. Of course we still want your feedback so keep it coming, but I think you are going to be very impressed with the new lessons!
Also, many students have asked about the “old” or shall we say “classic” ATCoD and if it will be removed once we are complete with the new materials. The answer is NO. If you want nostalgia, want a different “take on the technologies”, or just want to hear a different voice, you will always be able to access the classic ATCoD.
I cannot wait to “see you” in class, and as always, thank you for choosing INE.
I just want to thank everyone for the awesome topic recommendations we have been flooded with for our upcoming Open Lectures.
If you do not see your topic listed below – do not fret! We will get to it soon…

NOTE: The March 16th Open Lecture will be available for ANY guests that would like to attend free of charge. We will also be having an exciting prize giveaway during the event…you will not want to miss it!
You just cannot assume anything when you sit for your Version 4.0 CCIE R&S Lab Exam. One of the former assumptions we could make with Version 3.x was that our Frame Relay Switch is going to be just fine and dandy. Therefore, if you examined your PVC health (status) and you saw DELETED, you could immediately inspect your Frame Relay map statements, or your frame-relay interface-dlci commands for a typo in the DLCI.
But in this new exam (Troubleshooting section or Configuration section), nothing is off limits from your problem scope. OK, well, to be more accurate, most Layer 1 issues are still indeed out of scope. In fact, in the Troubleshooting section, Layer 1 really cannot be an issue since the devices we are troubleshooting are actually virtual routers. You cannot even run up against a bad cable there! But still, there is a lot more that we can be asked to troubleshoot than in the past. And if you think about the Core Knowledge section, they could even ask Layer 1 troubleshooting-related questions there instead!
In this blog post (dedicated to my current Advanced Troubleshooting Bootcamp Live Class), we will examine Frame Relay troubleshooting where the Frame Relay Switch rears its rather ugly head.
Many students are getting excited for the new CCNP here at INE – and these students are not just those interested in pursuing their CCNP certification. The new TSHOOT course is certainly going to compliment our best-selling Advanced Troubleshooting Bootcamp for those students pursuing their CCIE R&S.
Here is the list of specific technologies this new course will aid us in troubleshooting:
