Advanced Carrier Supporting Carrier Design
LDP is the most commonly used label distribution protocol in today MPLS networks. Although it lacks of Traffic Engineering, Admission Control, Fast Reroute capabilities, it scales very well because of its Multi Point to Point Label Switched Path.BGP can also assign a label for the IP and also for the VPN prefixes and in this article I… Read More »

Response: My Industry Thoughts in 30 Seconds
Ivan posted his answers to 3 questions posed by a media agency. I got the same email and perhaps my thoughts might add something to the discussion. Q. What can enterprises do to ensure that their infrastructure is ready for next-gen networking technology implementations emerging in the next decade? Hire more people and invest in […]

Industry Thoughts in 30 seconds
A while ago someone working for an IT-focused media site approached me with a short list of high-level questions. Not sure when they’ll publish the answers, so here they are in case you might find them interesting:
What can enterprises do to ensure that their infrastructure is ready for next-gen networking technology implementations emerging in the next decade?
Next-generation networks will probably rely on existing architectures and forwarding mechanisms, while being significantly more uniform and heavily automated.

On Friday evening we are going be pushing an update to the community with some exciting new features. In addition to that you will notice,An Update on IPv6
In the coming weeks another Regional Internet Registry will reach into its inventory of available IPv4 addresses to hand out and it will find that there is nothing left. This is by no means a surprise, and the depletion of IPv4 addresses in the Internet could be seen as one of the longest slow motion train wrecks in history. As of mid June 2015 ARIN has 2.2 million addresses left in its available pool, and at the current allocation rate it will take around 30 days to run though this remaining pool. What does this mean for IPv6?Open Source Routing: Practical Lab
Earlier, I wrote about some interesting open source routing software that I’ve been exploring lately. In this post, I’ll provide you with some tools to get this lab running on your lab, using Vagrant and Ansible.
In this post, I’ll be using VirtualBox, and also Ansible and Vagrant. For this purpose, I’m assuming you’re at least somewhat familiar with these tools.
Please checkout my GitHub repository for access to the latest versions of all of the files we’ll discuss below - and an easy way to spin all of this up yourself.
Topology
First, here’s the topology we’ll be working with.
All “circuits” are implemented using VirtualBox host networks, described in the Vagrantfile:
# -*- mode: ruby -*-
# vi: set ft=ruby :
VAGRANTFILE_API_VERSION = "2"
Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|
config.vm.box = "trusty64"
config.vm.box_url = "http://cloud-images.ubuntu.com/vagrant/trusty/current/trusty-server-cloudimg-amd64-vagrant-disk1.box"
config.vm.define "r1" do |r1|
r1.vm.host_name = "r1"
r1.vm.network "private_network",
ip: "192.168.12.11",
virtualbox__intnet: "01-to-02"
r1.vm.network "private_network",
ip: "192.168.31.11",

Even though im still in San Diego, Cisco Live! US 2015 is but a memory.
But what a memory it is! It being my first time attending a Cisco Live conference, I didn’t really know what to expect.
What I was met with, was a conference full of really sharp and nice people. The conference staff was very helpful and polite and really made an impression on me, from the time I first stepped onto the pavement outside San Diego convention center.
We (I brought my better half to the US) arrived very late on saturday, so after a good nights sleep I took the bus to the convention center to register and pick up the first piece of swag, the famous Cisco Live bag.
One of the great benefits of attending the conference was meeting with my good friend Daniel Dib (from lostintransit.se). I hadn’t seen him since January, so it was really cool to meet up with him during the week.
On Monday Daniel and I attended a session together, but most other sessions I went to alone. For the record, I paid for this trip out of my own pocket, so I didn’t have any co-workers Continue reading
Cisco Live 2015 – Helping Others
Another year, another Cisco Live. Boy, was it a good one. San Diego is a great city, and convention center there is plenty big to take care of all 25k attendees. On top of that, the city itself is equipped to handle groups of 40 roaming the streets looking for food and entertainment.
This year’s event had the usual stuff that everyone talks about – breakout session, keynotes, exams, etc. – but Cisco stepped outside of technology this year by helping others.
- Stop Hunger Now Volunteer Space – Cisco partnered with Stop Hunger Now and set up a space where attendees could assemble meal kits to fight hunger worldwide. I believe the final number was 100,656 kits assembled, which is a fantastic number. I’m ashamed to say, though, that I missed this due to scheduling issues, but I’m proud of Cisco and the attendees for participating.
- Mike Rowe Works Foundation – The keynote speaker this year was Mike Rowe, whom most of us know from his TV show Dirty Jobs. His foundation helps to support skilled labor movements in order to keep all jobs meaningful. As part of his appearance, Cisco gave his foundation a nice check for $20,000 and promised another Continue reading
