One of the previous BGP labs explained how you can use session templates to configure common TCP or BGP session parameters. Some BGP implementations have another templating mechanism: policy templates that you can use to apply consistent routing policy parameters to an EBGP neighbor. You can practice them in the next BGP lab exercise.

On February 6th, 2024 we announced eight new models that we added to our catalog for text generation, classification, and code generation use cases. Today, we’re back with seventeen (17!) more models, focused on enabling new types of tasks and use cases with Workers AI. Our catalog is now nearing almost 40 models, so we also decided to introduce a revamp of our developer documentation that enables users to easily search and discover new models.
The new models are listed below, and the full Workers AI catalog can be found on our new developer documentation.

Today’s catalog update includes a number of new language models so that developers can pick and choose the best LLMs for their use cases. Although most LLMs can be generalized to work in any instance, there are many benefits to choosing models that are tailored for a specific use case. We are excited to bring you some new large language models (LLMs), small language models (SLMs), Continue reading
There is more than one way to get to a large language model with over 1 trillion parameters that can do lots of different things and enterprises can use to create AI training and inference infrastructure to extend and enrich their thousands of applications. …

Instead of being a protocol, EVPN is a solution that utilizes the Multi-Protocol Border Gateway Protocol (MP-BGP) for its control plane in an overlay network. Besides, EVPN employs Virtual extensible Local Area Network (VXLAN) encapsulation for the data plane of the overlay network.
Multi-Protocol BGP (MP-BGP) is an extension of BGP-4 that allows BGP speakers to encode Network Layer Reachability Information (NLRI) of various address types, including IPv4/6, VPNv4, and MAC addresses, into BGP Update messages.
The MP_REACH_NLRI path attribute (PA) carried within MP-BGP update messages includes Address Family Identifier (AFI) and Subsequent Address Family Identifier (SAFI) attributes. The combination of AFI and SAFI determines the semantics of the carried Network Layer Reachability Information (NLRI). For example, AFI-25 (L2VPN) with SAFI-70 (EVPN) defines an MP-BGP-based L2VPN solution, which extends a broadcast domain in a multipoint manner over a routed IPv4 infrastructure using an Ethernet VPN (EVPN) solution.
BGP EVPN Route Types (BGP RT) carried in BGP update messages describe the advertised EVPN NLRIs (Network Layer Reachability Information) type. Besides publishing IP Prefix information with IP Prefix Route (EVPN RT 5), BGP EVPN uses MAC Advertisement Route Continue reading
Today, we are proud to open source Pingora, the Rust framework we have been using to build services that power a significant portion of the traffic on Cloudflare. Pingora is released under the Apache License version 2.0.
As mentioned in our previous blog post, Pingora is a Rust async multithreaded framework that assists us in constructing HTTP proxy services. Since our last blog post, Pingora has handled nearly a quadrillion Internet requests across our global network.
We are open sourcing Pingora to help build a better and more secure Internet beyond our own infrastructure. We want to provide tools, ideas, and inspiration to our customers, users, and others to build their own Internet infrastructure using a memory safe framework. Having such a framework is especially crucial given the increasing awareness of the importance of memory safety across the industry and the US government. Under this common goal, we are collaborating with the Internet Security Research Group (ISRG) Prossimo project to help advance the adoption of Pingora in the Internet’s most critical infrastructure.
In our previous blog post, we discussed why and how we built Pingora. In this one, we will talk about why and how you might Continue reading
Reading RFCs is a great source of information for understanding all the details of a protocol. Often they do require the reader to be quite technical and the terminology can be confusing if you aren’t used to the type of language and writing style used in RFCs. In this post, I go through some of the most important terminology in EVPN and VXLAN to help you build your understanding of the different forwarding constructs and how they interact.
The picture below shows some of the most important terminology in EVPN:
Let’s go through the terms used in the diagram and some additional ones:
Markku Leiniö sent me an interesting observation after writing a series of DHCP-relaying-related blog posts:
I was first using VyOS, but it uses the ISC DHCP relay, and that software relays unicast packets. The DHCP procedures eventually worked fine, but getting sensible outputs and explanations was a nightmare.
I quickly reproduced the behavior, but it took me almost half a year to turn it into a blog post. Engaging in a round of yak shaving (I wanted to implement DHCP in netlab first) didn’t exactly help, either.

I updated the status of the open-source network simulation and network emulation projects tracked in this blog. I found no new projects to add to my lists in 2023 or early 2024. I also did not have to delete any projects because they all seem to have an acceptable level of support in 2024.
Read the rest of this post for information about the latest open-source network simulator releases, as of the end of February, 2024.

I stumbled upon an “I want to dive deep into VXLAN and plan to build a virtual lab” discussion on LinkedIn1. Of course, I suggested using netlab. After all, you have to build an IP core and VLAN access networks and connect a few clients to those access networks before you can start playing with VXLAN, and those things tend to be excruciatingly dull.
Now imagine you decide to use netlab. Out of the box, you get topology management, lab orchestration, IPAM, routing protocol design (OSPF, BGP, and IS-IS), and device configurations, including IP routing and VLANs.
