CCIE Collaboration Written

Routing Protocol for Low Power and Lossy Networks

Leave a comment

Routing Protocol for Low power and Lossy networks

In this article we shall take a high-level look at an IoT protocol called RPL (pronounced ripple). The long-winded name is Routing Protocol for low power and lossy networks (LLN). Candidates sitting any CCIE Written exam should have some exposure to this protocol as part of the Evolving Technologies section that was added to all CCIE Written exams in July 2016.

Imagine a network of sensors monitoring noise or heat inside a building. All these sensors are continuously transmitting data wirelessly. It doesn’t make sense if you have to replace the battery or sensor every few weeks. Sensor designs should last years before needing to be replaced. They should also be standalone and not connected to any power source. Hence the term Low-Power and Lossy Networks (LLN).

Student Testimonial – Jeremy Brown – CCIE #54089

Leave a comment

I decided to pursue my CCIE Collaboration after accidentally letting my CCNP expire about a year ago. I watched all the videos from a competitor and while thorough they are not nearly as to the point as CollabCert’s videos and training are. Vik has a training style that is easy to pay attention to and watch over and over. I purchased the whole package of workbooks, training videos, and both boot-camps. I took the boot-camps a month apart. It is a lot to digest and work on. I used the CollabCert Rack rentals using the phones, router, and switch I purchased from a former student. I am not strong in route/switch being a long time voice guy and I needed assistance getting going (on the weekend) and Vik was always able to point me in the right direction. He went above and beyond there.

It took me three separate attempts and after each attempt Vik was there for support and to help me understand what I needed to work on. I don’t know where I would have been without that and the time he spent with me went beyond just sitting in a boot-camp and leaving. That is very much appreciated. I  would advise getting the whole package. I felt completely euphoric seeing that “Pass” when the email came. I could not have done it without Vik.

Student Testimonial – Aaron Hagerman – CCIE # 53815

I would like first to say thank you for all your help. As soon as I found out about CollabCert I knew this was the place to help me achieve my CCIE dreams. In the past when I was studying for the CCIE Voice track I thought I was on the right track. I took the lab and I thought for sure I passed as soon as I walked out, only later to find out I wasn’t close. It’s very disappointing when this happens time and time again.

The first week of attending CollabCert I was able to find out not only the correct way to study but also shortcuts and tricks to help me attain my CCIE. Once I started the second week of the boot camp you really see the value in the program. Never before was I given feedback on a completed lab before this class. This allowed me to not only see my errors but give me confidence once I was able to complete the lab with a passing grade from Vik. This would have been a great class if it all ended here, but it didn’t. Continue reading Student Testimonial – Aaron Hagerman – CCIE # 53815 →

CCIE Collaboration Overview

State of the Union – Shift to the Cloud (CCIE Collaboration)

3 Comments

Unless you have been hiding beneath a rock for the past few months, you will have noticed that the Collaboration market is trending towards the cloud and that means less on-premise equipment for Collaboration Engineers to install, configure and maintain. Central to Cisco’s collaboration cloud strategy is Cisco Spark. This is an app that allows secure business messaging / file sharing, meetings through Spark rooms and video/audio calls.

In July 2016 at Cisco Live in Las Vegas, Cisco SVPs Rowan Trollope and Jens Meggers, and Cisco VP Jonathan Rosenberg gave a sneak peek into what the future holds for Cisco Spark. The demonstration at the keynote showed the audience that a new telepresence unit can be taken out of the box and connected to the cloud in a matter of minutes with very little technical configuration. There is no need for anything on-prem-  you just need an account in the cloud and the Serial Number of your client you are good to go. Furthermore, in Fall 2016 Spark will be integrated into iOS 10 which will allow enterprise voice/video calls to be made from an iPhone or iPad. Lots of cool new things in the pipeline! Keep a close eye on Rowan’s blog.

UCM

Unified Mobility and Mobile Voice Access

20 Comments

Mobility and Mobile Voice Access

Single Number Reach/Mobile Voice Access

In this article we will discuss the concepts and configuration behind Cisco Unified Mobility in UCM 9.x. Cisco Unified Mobility can be broken down into two main functional components- Mobile Connect (Single Number Reach/SNR) and Mobile Voice Access (Direct Inward System Access/DISA).

Assumptions before we begin

  • Before we dive into Unified Mobility specific configuration, we need to (as always!) make some assumptions.
  • Firstly, we assume as have a fully configured dialplan in UCM using an H323 gateway (no you are not mistaken- it is 2016). The DID range allocated to the site from the PSTN is 9723033XXX.
  • Secondly- we have a device registered and working. This deskphone has been allocated the DID 9723033001.
  • Thirdly- we have an End User created- this end user is called “sitebone”.

Single Number Reach
