Should You Build or Buy a Router?
Patrik Schindler sent me an interesting comment to my Open-Source DMVPN Alternatives blog post:
I’ve done searches myself some time ago about the readymade Linux distros supporting DMVPN and got exactly what I asked for.
Glancing over that page appalled me: Different stuff with different configuration languages, probably the need to restart things, thus generating service outages for configuration changes…
Your blog is heavily biased towards big deployments with good opportunities for automation, and the diversity of different components can be easily hidden behind automation scripts of choice. Smaller deployments are almost never being able to compensate the initial overhead of creating all the automation fuzz, and from that perspective, I must admit that configuring a Cisco router feels way more smooth to me.
Welcome to the build-or-buy dilemma, router edition.

Update on recent VoIP attacks: What should I do if I’m attacked?
Attackers continue targeting VoIP infrastructure around the world. In our blog from last week, May I ask who’s calling, please? A recent rise in VoIP DDoS attacks, we reviewed how the SIP protocol works, ways it can be abused, and how Cloudflare can help protect against attacks on VoIP infrastructure without impacting performance.
Cloudflare’s network stands in front of some of the largest, most performance-sensitive voice and video providers in the world, and is uniquely well suited to mitigating attacks on VoIP providers.
Because of the sustained attacks we are observing, we are sharing details on recent attack patterns, what steps they should take before an attack, and what to do after an attack has taken place.
Below are three of the most common questions we’ve received from companies concerned about attacks on their VoIP systems, and Cloudflare’s answers.
Question #1: How is VoIP infrastructure being attacked?
The attackers primarily use off-the-shelf booter services to launch attacks against VoIP infrastructure. The attack methods being used are not novel, but the persistence of the attacker and their attempts to understand the target’s infrastructure are.
Attackers have used various attack vectors to probe the existing defenses of targets and try to Continue reading

Learning from Facebook’s Mistakes
On October 4th Facebook managed to achieve one of the more impactful of outages of the entire history of the Internet, assuming that the metric of "impact" is how many users one can annoy with a single outage. What can we as an industry learn from this outage to ensure that we can avoid a recurrence of such a widespread outage in other important and popular service platforms?Hedge 103: BGP Security with Geoff Huston
Our community has been talking about BGP security for over 20 years. While MANRS and the RPKI have made some headway in securing BGP, the process of deciding on a method to provide at least the information providers need to make more rational decisions about the validity of individual routes is still ongoing. Geoff Huston joins Alvaro, Russ, and Tom to discuss how we got here and whether we will learn from our mistakes.

Ansible Automation Platform will seamlessly integrate with private automation hub for publishing and pulling execution environment container images.
Who uses private automation hub?
Private automation hub is intended for curating automation content from creators and making it seamlessly accessible to operators. It makes it easy to share these execution environments, which make Continue reading
Wireless LANS in the 21st Century
The power and potential of the next generation cognitive campus are transformative as the industry undergoes a massive transition to hybrid work in the post-pandemic era. A key underpinning to successful campus networking deployments has been our very first acquisition of Mojo Networks for cognitive Wi-Fi. Arista’s entry into wireless is only in its third year, yet the advances in this space will be profound over the next decade.
