Today on the Tech Bytes podcast we’re sponsored by Palo Alto Networks, which is expanding its cloud partnership by integrating with Azure to help customers achieve a multicloud strategy.

At the most basic level, there are only three BGP policies: pushing traffic through a specific exit point; pulling traffic through a specific entry point; preventing a remote AS (more than one AS hop away) from transiting your AS to reach a specific destination. In this series I’m going to discuss different reasons for these kinds of policies, and different ways to implement them in interdomain BGP.
There are many reasons an operator might want to select which neighboring AS through which to send traffic towards a given reachable destination (for instance, 100::/64). Each of these examples assumes the AS in question has learned multiple paths towards 100::/64, one from each peer, and must choose one of the two available paths to forward along.
In the following network—
From AS65001’s perspective
Assume AS65001 is some form of content provider, which means it offers some service such as bare metal compute, cloud services, search engines, social media, etc. Customers from AS65006 are connecting to its servers, located on the 100::/64 network, which generates a large amount of traffic returning to the customers.
From the perspective of AS hops, it appears the path from AS65001 to AS65006 is the same length—if this Continue reading
Start that business. You have sufficient technical & business skills, and you can figure out what you don’t know. Take the chance now while you have little at risk.
You’re not the standard everyone else is supposed to live up to. Work on your own faults. They are legion.
Your boss is your boss for a reason. You’re not the boss for a reason, too. When you understand and accept those reasons, you’ll reduce the workplace friction you keep experiencing.
Meritocracy doesn’t mean what you think it means. Being good at your job doesn’t mean you deserve a promotion.
More responsibility comes easy, because no one wants it. More compensation comes hard, because everyone wants it.
Business owners who cheat their partners & customers will cheat their employees, too. Run at the first sign of dishonest business dealings.
Define your goals so you know when you’ve reached them. Otherwise, you’ll exhaust yourself with endless effort.
You are your own worst critic. Take yourself less seriously.
When you work for someone else, you are a replaceable component in a larger machine. This is by design.
You don’t Continue reading
In this video, Russ White examines two advanced options for your underlay control plane: distoptflood and RIFT. He explores the basics of distopflood and RIFT, optimizations in distoptflood, centralized flooding, how RIFT works, and more. You can subscribe to the Packet Pushers’ YouTube channel for more videos as they are published. It’s a diverse a […]

Syed Khalid Ali left the following question on an old blog post describing the use of IBGP and EBGP in an enterprise network:
From an enterprise customer perspective, should I run iBGP or iBGP+IGP (OSPF/ISIS/EIGRP) or IGP while doing mutual redistribution on the edge routers. I was hoping if you could share some thoughtful insight on when to select one over the another?
We covered tons of relevant details in the January 2022 Design Clinic, here’s the CliffNotes version. Keep in mind that the road to hell (and broken designs) is paved with great recipes and best practices, and that I’m presenting a black-and-white picture because I don’t feel like transcribing the discussion we had into an oversized blog post. People wrote books on this topic; I’m pretty sure you can search for Russ White and find a few of them.
Finally, there’s no good substitute for understanding how things work (which brings me to another webinar ;).

Hello my friend,
Today we are going to discuss a real-life experience, how network automation helped us to save a lot of time and significantly improve a quality of the medium size data centre. You will learn about the problem, which audit was to solve and how Python leveraging Nornir and Scrapli solved it.

We, humans, are incredible creatures. We can create. We can write songs and compose music; we can invent new drugs and find new materials. We can develop new software and tools. However, in order to be able to do that, we need to have a free time and not to worry about anything. That’s why we need to rely on different tools, which can do routine tasks requiring a lot of concentration at least as good as we, humans, can. Probably, even better than we. Audit is one of such tasks, and in IT world it definitely Continue reading
