Posts from ‘CCIP’
Just ahead of our brand new CCNA Voice live online bootcamp beginning this Monday, I thought it might be nice to provide an easy-to-follow graphic for those starting out in Voice (or on any other Cisco networking track). This graphic was from last year, but remains quite easy to follow for each and every Cisco track.
Be sure you have a high resolution set if you wish to see the entire thing, otherwise scrolling may be necessary.
When we ask students “what are your weakest areas” or “what are your biggest areas of concern” for the CCIE Lab Exam, we typically always here non-core topics like Multicast, Security, QoS, BGP, etc. As such, INE has responded with a series of bootcamps focused on these disciplines.
The IPv4/IPv6 Multicast 3-Day live, online bootcamp, and the associated Class On-Demand version seeks to address the often confounding subject of Multicast. Detailed coverage of Multicast topics for the following certifications is provided:
Cisco Certified Network Professional (CCNP)
Cisco Certified Design Associate (CCDA)
Cisco Certified Design Professional (CCDP)
Cisco Certified Design Expert (CCDE)
Cisco Certified Internetwork Expert Routing & Switching (CCIE R&S)
Cisco Certified Internetwork Expert Service Provider (CCIE Service Provider)
Cisco Certified Internetwork Expert Security (CCIE Security)
To purchase the live and on-demand versions of the course for just an amazing $295 – just click here. The live course runs 11 AM to 6 PM EST US on September 29,30, and October 1.

One of the frequent questions I hear regarding L3VPNs, is regarding the bottom VPN label. In this article, we will focus on the control plane that provides both the VPN and transit labels, and then look at the data plane that results because of those labels.
In the topology, there are 2 customer sites (bottom right, and bottom left). The BGP, VRFs, Redistribution, etc are all configured to allow us to focus on the control and data plane. Lets begin by verifying that R1 is sourcing the network, 220.127.116.11/32.
A debug verifies that R1 is sending the updates for 18.104.22.168 to R2.
In this blog post we’re going to discuss the fundamental logic of how MPLS tunnels allow applications such as L2VPN & L3VPN to work, and how MPLS tunnels enable Service Providers to run what is known as the “BGP Free Core”. In a nutshell, MPLS tunnels allow traffic to transit over devices that have no knowledge of the traffic’s final destination, similar to how GRE tunnels and site-to-site IPsec VPN tunnels work. To accomplish this, MPLS tunnels use a combination of IGP learned information, BGP learned information, and MPLS labels.
Our BGP class is coming up! This class is for learners who are pursuing the CCIP track, or simply want to really master BGP. I have been working through the slides, examples and demos that we’ll use in class, and it is going to be excellent. If you can’t make the live event, we are recording it, so it will be available as a class on demand, after the live event. More information, can be found by clicking here.
One of the common questions that comes up is “Why does the router choose THAT route?
We all know, (or at least after reading the list below, we will know), that BGP uses the following order, to determine the “best” path.
So now for the question. Take a look at the partial output of the show command below: Continue Reading
Last week we wrapped up the MPLS bootcamp, and it was a blast! A big shout out to all the students who attended, as well as to many of the INE staff who stopped by (you know who you are ). Thank you all.
Here is the topology we used for the class, as we built the network, step by step.
The class was organized and delivered in 30 specific lessons. Here is the “overview” slide from class: Continue Reading
