On Building a Personal Brand
How do you balance loyalty to yourself and loyalty to the company you work for?
This might seem like an odd question, but it’s an important component of work/life balance many of us just don’t think about any longer because, as Pete Davis says in Dedicated, we live in a world of infinite browsing. We’re afraid of sticking to one thing because it might reduce our future options. If we dedicate ourselves to something bigger than ourselves, then we might lose control of our direction. In particular, we should not dedicate ourselves to any single company, especially for too long. As a recent (excellent!) blog post over at the ACM says:
The idea that we should control our own destiny, never getting lost in anything larger than ourselves, is ubitiquos like water is to a fish. We don’t question it. We don’t argue. It is just true. We assume there are three people who are going to look after “me:” me, myself, and I.
I get it. Honestly, I do. I’ve been there Continue reading

BGP LS, BGP Link-State is used to distribute Link state information and traffic engineering attributes from the network nodes to the Centralized TE controller. RSVP-TE has been providing resource allocation and providing an LSP with the distributed path computation algorithm (CSPF) for decades. It requires topology information from the network and only link-state IGP protocols such as OSPF and IS-IS can carry the topology information required for the controller to set up a shortest from each node to each destination prefix.
In order to overcome Bin Packing, Dead Lock, or Network-wide optimal traffic engineering, centralized controllers have been used for a long time. Because with the distributed computation for Traffic Engineering, the above issues might arise.
RFC 7752 specifies the details of North-Bound Distribution of Link-State and Traffic Engineering (TE) Information Using BGP.
PCE (Path Computation Element) is an SDN controller which provides optimal path computation in Multi Area and Multi AS (Autonomous System) deployments.
It requires Link State and Traffic Engineering attributes such as Link coloring, SRLG, reserved bandwidth, etc., from the network.
Link state IGP protocols (OSPF, IS-IS) can be used for this purpose but they are considered chatty and non-scalable, thus BGP with Continue reading
CCIE Service Provider v5.0 What, Why, When?
In this post, we will look at what is CCIE Service Provider v5.0, what comes with it, which technologies we need to learn, what is the difference between CCIE SP v4 and CCIE SP v5, why you should study for CCIE Service Provider v5, when you should study for CCIE SP exam, after which certificate you should aim it for, we will look at all of these questions.
What is the Cisco CCIE Service Provider v5 Exam?
The CCIE Service Provider v5 lab exam is testing skillsets related to the service Provider solutions integration, interoperation, configuration, and troubleshooting in complex networks. CCIE SP v5 is the latest version of the CCIE Service Provider lab exam. When the candidates pass this exam, they get their CCIE number.
This certification syllabus covers most, if not all real-life Service Provider network technologies.
What is the difference between CCIE SP v4 and CCIE SP v5?
From the technology standpoint, the biggest difference between CCIE SPv4.1 and the CCIE SP v5.0 exam is Network Programmability and Automation Module. It is 20% of the entire exam, thus very important in the CCIE Service Provider exam. You can access Orhan Ergun’s CCIE SP Network Continue reading

Red Hat Ansible Automation Platform on Microsoft Azure – Network Access – blog #1
Introduction
In this blog series we will discuss the deployment of Red Hat Ansible Automation Platform on Microsoft Azure, specifically focusing on the deployment access types and what that means for accessing Red Hat Ansible Automation Platform on Azure after deployment completion.
Deployment Access Types
First let’s start by discussing the different deployment access types.
During deployment, Red Hat Ansible Automation Platform on Azure will present an option called “Access” that determines how you will access the user interfaces.
Access Selection at Deploy Time
| Deployment Type |
Details |
| Public |
Public deployments allow ingress to the user interfaces over the public internet. Upon deployment, a domain name is issued to the Red Hat Ansible Automation Platform on Azure instance, and users will be able to navigate to the domain to login. This is the easiest approach to deploy because there is no configuration required to access Red Hat Ansible Automation Platform on Azure. Public Access Architecture Diagram below |

| Deployment Type |
Details |
| Private |
Private deployments omit access from the public internet. When deployed, Red Hat Ansible Automation Platform on Azure will reside in an isolated Azure VNET with no access from external sources or even other Continue reading |
Orhan Ergun CCIE Enterprise Infrastructure Course Review 1
I see some people have been asking what other people are thinking about Orhan Ergun’s CCIE Enterprise course, thus starting today to share what other people share about us on their blog posts as well. Not just on social media, but with these blog posts, because they are able to share more thoughts about us, I think it is very valuable feedback for everyone.
I would like to start with the website ‘ samovergre.com ‘.
He is our CCIE Enterprise student and you can find his CCIE study plan on this page. He is sharing feedback about our CCIE Enterprise training and other study materials he uses for his CCIE Enterprise study.
Why Orhan Ergun CCIE Enterprise Infrastructure Course?
One thing that was very important there was that He understand the uniqueness of our CCIE Enterprise Training. It is the design part.
Everyone can teach you how to configure routers or routing protocols, but a design mindset is a completely unique thing and for years, if you are a Network Engineer, probably you have heard about our CCDE training and its success too.
Now, we continue delivering our design knowledge and experience to our CCIE students as well and Continue reading
netlab: Combining VLANs with VRFs
Last two weeks we focused on access VLANs and VLAN trunk netlab implementation. Can we combine them with VRFs? Of course.
The trick is very simple: attributes within a VLAN definition become attributes of VLAN interfaces. Add vrf attribute to a VLAN and you get all VLAN interfaces created for that VLAN in the corresponding VRF. Can’t get any easier, can it?
How about extending our VLAN trunk lab topology with VRFs? We’ll put red VLAN in red VRF and blue VLAN in blue VRF.

Cloudflare is redefining employee well-being in Japan
This post is also available in 日本語
“You can accomplish anything if you do it. Nothing will be accomplished unless you do it. If nothing is not accomplished, that’s because no one did it.“
— Yozan Uesugi
Long hours and hard work. If you ask anyone in Japan what our work culture is like, chances are, these are the words that will come to mind. Different countries have their own cultures and also specific work habits and ways of having a work-life balance. The pandemic brought everyone (companies and their people) a new reality, new lessons, and new habits. Here at Cloudflare, our thinking around where and how we do our best work has evolved over the course of the pandemic. We care about addressing the diverse needs of our workforce and our policies and benefits are designed to optimize for their flexibility and needs. To that end, Cloudflare Japan is making a few important changes to our employee benefits:
- “take what you need” time off for all our employees
- 16-week gender-neutral paid parental leave
- flexible working hours
First, let’s try to understand a bit of the Japanese work culture. According to Japan’s labor laws, Japanese employed workers are Continue reading
BGP communities part 3: Customer BGP Traffic Engineering communities
If you’ve ever been asked to prioritize one internet connection over another for any variety of reasons, cost, latency, SLA, etc… this is for you.
Often I hear the same tactics to solve this problem:
- AS-PATH prepending
- conditional advertisements
- scripting
- some other manual process
However, most carriers offer customer BGP TE communities that you can use to influence traffic within their AS, with one notable exception Hurricane Electric. If you’re not sure what a BGP community take a quick look at this post on them first.
Lets explore how to utilize these, where to find them, and how they might give more deterministic path selection than the options laid out above.

Default behavior with no modification
First to get familiar with the topology and show reachability we’ll leave all settings as “defaults” with no modifications.
