For now I configured the simplest possible variant of RT assignment – one vrf-target for all ES and VNI routes (vrf-target target:65000:1):
Protecting end users starts with understanding their use and integration of services. For authoritative DNS, this includes human error when copying and pasting information between interfaces. After purchasing a new domain, such as “containercult.com,” the end user configures authoritative nameservers. Delegation is a “set it and forget it” operation; it is often made outside of scope of continuous integration pipelines and automated deployment systems. To quantify this risk and reconcile it with reality, we started to look at the existence of nameserver record typos in the .COM zone file.
There are typos in nameserver records for a number of authoritative DNS providers made across a number of zones, making it clear that end users make delegation typos. The existence of the typo is one thing, it’s another when the typo has been registered and another provider is serving responses. One of the typos of interest was dynect.ne, which was registered some time in February of 2016. At that time, it was delegated to a pair of authoritative nameservers operated by myhostadmin.net, a name related to a Chinese hosting provider. Sometime around January 2017, the authoritative nameservers changed over to Yandex, the Russian internet services provider, and Continue reading
GRE Tunnels GRE tunnels are by far most common tunnelling technology. Very easy to setup, troubleshoot and operate. But in large scale deployment, configuring GRE tunnels become cumbersome, because GRE tunnel is a point to point tunnel. GRE Tunnel Characteristics • GRE tunnels are manual point to point tunnels. Tunnel end points are not automatically […]

Net neutrality is one of those topics that should never have existed, but of course it inevitably erupts every so often, so here we go…
Not so long ago Robert Graham published his anti-net-neutrality arguments which are (no surprise) not much different from what I wrote when I still cared about this argument (here, here, here and here). While I agree with his overall perspective, I completely disagree with his view of Comcast’s initial response to network congestion.

I sat with Greg, Kathleen, and Alia to talk about “ordinary engineers” getting involved in the IETF while we were in Prague. Believe it or not, this time I didn’t get out into the city at all other than walking between the hotel I was staying at and the venue hotel. I try to always take “one day off” and do something around the city we are in, but the schedule didn’t allow it this time. Anyway, here is the link—

The best education materials are inclusive, equitable, and high-quality, and they promote lifelong learning. One of the best tools for sharing these types of materials is the Internet. However, the body of education materials currently available online is not yet as inclusive and equitable as it could be.
So many of us default to looking online for anything we want to know. Wikipedia alone covers more than 40 million articles in nearly 300 languages. With this scope, it can sometimes feel like things that haven’t happened online haven’t happened in real life. And that’s a problem — especially because so many of the facts that don’t make their way online are about women, people of colour, and the global south.
