Configuring 6PE Route Reflector on Cisco IOS

Imagine you want to deploy a BGP route reflector for MPLS 6PE or L3VPN service. Both services run over MPLS LSPs, use IPv4 BGP sessions, and use IPv4 next hops for BGP routes. There’s absolutely no reason to need IPv6 routing on a node that handles solely the control-plane activity (it never appears as a BGP next hop anywhere), right? Cisco IOS disagrees, as I discovered when running route reflector integration tests for netlab 6PE and (MPLS) L3VPN functionality.

Most platforms failed those tests because we forgot to configure route-reflector-clients in labeled IPv6 and VPNv4/VPNv6 address families¹. That was easy to fix, but the IOS-based devices were still failing the tests, with nothing in the toolchain ever complaining about configuration problems.

Context Is Expensive

When it comes to learning and understanding, facts are easy. If I ask you how many bits are in an IPv4 address it’s a single answer. People memorize facts and figures like this all the time. It’s easy to recall them for tests and to prove you understand the material. Where things start getting interesting is when you need to provide context around the answer. Context is expensive.

Cognitive Costs

Questions with one correct answer or with a binary answer choice are easy to deal with cognitively. You memorize the right answer and move on with your life. IPv4 addresses are 32 bits long. The sun rises in the east. You like Star Wars but not Galatica 1980. These things don’t take much effort to recall.

Now, think about why those answers exist. Why does the sun rise in the east? Why are addresses 32 bits long? Why don’t you like Galactica 1980? The answers are much longer now. They involve nuance and understanding of things that are outside of the bounds of simple fact recall. For example, look at this video of Vint Cerf explaining why they decided on 32-bit addresses all the way back in the mid-1970s:

Packet Trimming Deep Dive – Part II

Receive Interface Group (Rx IFG)

The Receive Interface Group (Rx IFG) is the ingress pre-processing stage that handles the incoming Ethernet bitstream before the packet enters the Packet Processing Array (PPA) of the Receive Network Processing Unit (Rx NPU) in the Cisco Silicon One architecture.

Processing begins at the Rx MAC. The Rx MAC reconstructs (“delimits”) the Ethernet frame from the Physical Coding Sublayer (PCS) bitstream and verifies frame integrity by computing a Frame Check Sequence (FCS) using the CRC-32 algorithm. If the computed FCS does not match the received FCS value, the frame is considered corrupted and is dropped immediately at ingress. If the CRC check succeeds, the frame is admitted for further processing. 

Shallow classification and Traffic Class mapping

After frame validation, the Rx IFG identifies the Ethernet MAC header and detects the presence of IEEE 802.1Q VLAN tags. The Rx IFG performs shallow classification to efficiently manage hardware resources before deeper protocol parsing and forwarding decisions are executed in the Rx NPU. When an IEEE 802.1Q VLAN tag is present, the Rx IFG extracts the Priority Code Point (PCP) bits from the VLAN tag and maps them to an Internal Continue reading

On AI Agents Speaking BGP

I guess your LinkedIn feed is as full of AI nonsense as mine is, so I usually just skip all that posturing. However, every now and then, I stumble upon an idea that makes sense… until you start to dig deeper into it.

There was this post about AI agents speaking BGP with an associated GitHub repo, so I could go take a look at what it’s all about.

The proof-of-concept (so the post author) has two components:

How we rebuilt Next.js with AI in one week

_{*This post was updated at 12:35 pm PT to fix a typo in the build time benchmarks.}

Last week, one engineer and an AI model rebuilt the most popular front-end framework from scratch. The result, vinext (pronounced "vee-next"), is a drop-in replacement for Next.js, built on Vite, that deploys to Cloudflare Workers with a single command. In early benchmarks, it builds production apps up to 4x faster and produces client bundles up to 57% smaller. And we already have customers running it in production. 

The whole thing cost about $1,100 in tokens.

Next.js is the most popular React framework. Millions of developers use it. It powers a huge chunk of the production web, and for good reason. The developer experience is top-notch.

But Next.js has a deployment problem when used in the broader serverless ecosystem. The tooling is entirely bespoke: Next.js has invested heavily in Turbopack but if you want to deploy it to Cloudflare, Netlify, or AWS Lambda, you have to take that build output and reshape it into something the target platform can actually run.

If you’re thinking: “Isn’t that what OpenNext does?”, you are correct. Continue reading

Interesting: Open Space Events

Following a link in another Martin Fowler’s blog post, I stumbled upon his thoughts on Open Space events – a way to set up self-organizing events.

I’m not sure I’m brave (or young) enough to try it out, but if you’re planning to organize a small gathering (like a local Network Operator Group), this might be an interesting, slightly more structured approach than a Net::Beer event. It would also be nice to know whether someone managed to pull it off in an online format.

Real-time visualization of AI / ML traffic matrix

Heatmap is available on GitHub. The application provides a real-time traffic matrix visualization of end-to-end traffic flowing across an Ethernet fabric. Each axis represents an ordered list of network addresses. The x-axis is a flow source and the y-axis is a flow destination.

For example, the Heatmap above comes from a large high performance compute cluster running a mixture of tasks. Traffic is concentrated along the diagonal, indicating that the job scheduler is packing related tasks in racks so that most traffic is confined to the rack.

Note: Live Dashboards links to a number dashboards showing live traffic, including the Heatmap above.

The next Heatmap shows a very different traffic pattern. In this case, RoCEv2 traffic generated by GPUs performing a NCCL AllReduce/AllGather collective operation using a ring algorithm. During the collective operation, each GPU sends data to its immediate neighbor (modulo the number of GPUs) in a logical ring, resulting in two nearly continuous lines on either size of the diagonal: one for forward traffic, and the other for return traffic associated with each flow. The final example comes from a large data center hosting a mix of front end workloads. Unlike the backend networks, this network combines internal (East/West) Continue reading
