In this short article we’ll take a look at Cisco IOS static multicast routes (mroutes) and the way they are used for RPF information selection. Multicast routing using PIM is not based on propagation of any type of multicast routes – the process that was used say, in DVMRP. Instead, router performs RPF checks based on the contents of unicast routing table, populated by regular routing protocols. The RPF checks could be classified as either data-plane or control-plane. Data-plane RPF check applies when router receives a multicast packet, to validate if the interface and upstream neighbor sending the packet match RPF information. For data-plane multicast, the packet must be received from an active PIM neighbor on the interface that is on the shortest path to the packet source IP address, or RPF check would fail. Control-plane RPF check is performed when originating/receiving control-plane messages, such as sending PIM Join or receiving MSDP SA message. For example, PIM needs to know where to send the Join message for a particular (S,G) or (*,G) tree, and this is done based on RPF lookup for the source IP or RP address. Effectively for PIM, RPF check influences the actual multicast path selection in the “reversed way”: it carves the route that PIM Join message would take and thus affects the tree construction. In both control and data-plane RPF check cases, the process is similar, and based on looking through all available RPF sources.

Updated with 18 Month Plan!

Not only have I updated the post below quite a bit, but I have also now put together a spreadsheet that you are free to download and customize to your liking. It includes both a 12-month plan that closely resembles what is listed below, but it also includes an 18-month plan on the 2nd tab that can be used by those who simply cannot devote as much time as I propose in the below post. Simply change the start date and the rest will cascade. Use this spreadsheet to be able to propose a very comprehensive plan to your boss if you are getting corporate-backing.

Introduction

I often get questions in class or via email that go something like “I am just beginning my studies for CCNA Voice – do I really need a two year AAP subscription?” or “How can I best utilize INE’s products to attain the CCIE Voice exam”, or simply “Where should I start?”.

This document seeks to provide you with a detailed guideline to using each of the products that compliment INE’s complete Voice training program. This program structure has been designed under the realistic assumption that you may be able to dedicate roughly 4 days a week, with approximately 4 hours a day (16 hours a week) to some form of study (be it watching our lecture and demo-based VoDs, reading Cisco documentation and books found in our Recommended Voice Reading Book List, or practicing on lab equipment), and be able to span a total duration of roughly 55 weeks from the start of studying for your CCNA Voice exam, and progressing through the CCNP Voice exam, and finally onto being ready to sit for your first CCIE Voice Lab exam attempt. This works out to just around one year of studying, with around 4 weeks off. This could (and probably will) vary, depending on your schedule, as you will undoubtedly need to custom tailor this program a bit to your life. All-in-all, you are going to spend almost 900 hours. I realize that this is a very committed study schedule, and I also wholeheartedly realize the sacrifice involved to commit fully to such an undertaking, however know now that these are hours that you, later in life, will look back on and attribute to some of the most beneficial that you have ever spent in your professional career. So buckle-up, and prepare yourself for the ride.

Note: It is assumed that before beginning this regiment, that the candidate has already studied for and obtained the necessary CCNA (Routing and Switching) exam. If you have not yet completed this Cisco-prerequisite exam yet, we strongly recommend that you take our CCNA Associate Course – 640-802 first, and pass that required exam.

Brian Dennis and I attended Cisco Live! – Networkers this week, and both enjoyed the privilege of sitting down to talk privately with Yusuf Bhaiji (Program Manager over the entire CCIE program) and Ben Ng (Program Manager over the CCIE Voice track) for roughly 45 minutes. It was quite an enjoyable and spirited talk, and I believe it benefited both sides – our side to gain a better understanding of why some of the choices have been made, and theirs possibly to see things a bit more ‘through the eyes of the typical hard-studying student’. I would like to take a moment to jot down some of the highlights from our conversation, and then unpack them in a bit more detail, so that you may benefit from the open conversation.

Highlights

I’ll jot down some very simple, high-level topics that were discussed during our conversation, and then unpack them in more detail in the following section.

  • Upcoming changes to every CCIE Lab Exam
    • Protecting the integrity of the CCIE certification
    • Robust, matured results-based grading engine
    • Heuristic logic embedded into task wording
    • Accuracy and detail of lab score reports
    • Cisco’s CCIE Lab Delivery System and virtualization for mobile labs
    • No re-reads
  • CCIE Voice
    • Next blueprint version expectation
    • Topics for current and next blueprint versions
  • CCIE Data Center
    • CCIE Storage grows up
  • Reason behind Cisco.com CCIE Statistics web page being removed
