Juniper to MikroTik – BGP commands

About the Juniper to MikroTik series

In the world of network engineering, learning a new syntax for a NOS can be daunting if you need a specific config quickly.  Juniper is a popular option for service providers/data centers and is widely deployed across the world. 

This is a continuation of the Rosetta stone for network operating systems series.  We’ll be working through several protocols over series of posts to help you quickly move between different environments. 

While many commands have almost the exact same information, others are as close as possible.  Since there isn’t always an exact match, sometimes you may have to run two or three commands to get the information needed. 

Using EVE-NG for testing

We conducted all of this testing utilizing EVE-NG and the topology seen below.

Learning Elixir

Elixir is a dynamic functional programming language that runs on the Erlang virtual machine. In this post I will outline my reasoning for learning Elixir and document the resources used in the process. I will update the Books, Videos and Blogs section as I move through the learning...

Worth Reading: Cloud Complexity Lies

Anyone who spent some time reading cloud providers’ documentation instead of watching slide decks or vendor keynotes knows that setting up infrastructure in a public cloud is not much simpler than doing it on-premises. You will outsource hardware management (installations, upgrades, replacements…) and might deal with an orchestration system provisioning services instead of configuring individual devices, but you still have to make the same decisions, and take the same set of responsibilities.

Obviously that doesn’t look good in a vendor slide deck, so don’t expect them to tell you the gory details (and when they start talking about the power of declarative API you know you have a winner)… but every now and then someone decides to point out the state of emperor’s clothes, this time Gerben Wierda in his The many lies about reducing complexity part 2: Cloud.

VMware After Gelsinger: Integrating Fiefdoms For A Post-Hypervisor World

VMware's next CEO has two tasks: to construct a narrative about VMware's role and value as a company in a post-hypervisor world, and to integrate its various fiefdoms into a cohesive set of products that can provide greater utility when used together than when used individually.

Heavy Networking 558: No Time For Hardware – The Case For NFV

Network Functions Virtualization (NFV) transforms routers, load balancers, firewalls and other network devices into virtual instances that can be service-chained, spun up and down as needed, and are cloud-friendly. But if you're a hardware hugger or have been been burned by virtualization in the past, should you avoid NFV? Today's Heavy Networking guests want to change your mind. The Packet Pushers speak with Michael Pfeiffer, a Cloud Networking Architect for a VAR; and Brad Gregory, Senior Product Manager at Equinix.

Planning For The Worst Case You Can’t Think Of

Remember that Slack outage earlier this month? The one that happened when we all got back from vacation and tried to jump on to share cat memes and emojis? We all chalked it up to gremlins and went on going through our pile of email until it came back up. The post-mortem came out yesterday and there were two things that were interesting to me. Both of them have implications on reliability planning and how we handle the worst-case scenarios we come up with.

It’s Out of Our Hands

The first thing that came up in the report was that the specific cause for the outage came from an AWS Transit Gateway not being able to scale fast enough to handle the demand spike that came when we all went back to work on the morning of January 4th. What, the cloud can’t scale?

The cloud is practically limitless when it comes to resources. We can create instances with massive CPU resources or storage allocations or even networking pipelines. However, we can’t create them instantly. No matter how much we need it takes time to do the basic provisioning to get it up and running. It’s the old story of Continue reading

IT workforce suffering under COVID-19, waiting on herd immunity for rebound

For the first year since the dot-com bubble popped, IT salaries were largely flat in 2020, and tens of thousands of jobs were lost in 2020, according to a report from independent management consultants Janco Associates.Hardest-hit were middle management jobs at both large enterprises and smaller companies, where salaries actually dropped by about 0.08%, while executive and staff-level jobs remained steady or grew by a similarly small amount.“What’s been hard hit, mostly, are IT organizations and SMBs,” said Victor Janulaitis, the CEO of Janco, which published the report. “That’s where the majority of the IT jobs are in the marketplace today.”To read this article in full, please click here

Stable: GNS3 2.2.17 + VMware Fusion 12.1.0 + macOS 11.1 (Build 20C69)

Even with minor caveats, I seem to be in a better place with macOS 11.1 Big Sur versus macOS 10.15.7 Catalina. Big Sur is not a flawless experience for me yet, but I have hope it will become so as software makers have time to adjust to all of Apple's changes. And I'll take being able to run GNS3 labs without kernel panics as a big win.
