BGP Labs: Multivendor External Routers

Here’s a quick update on the BGP Labs project status: now that netlab release 1.6.4 is out, I could remove the dependency on using Cumulus Linux as the external BGP router.

You can use any device that is supported by bgp.session and bgp.policy plugins as the external BGP router. You could use Arista EOS, Aruba AOS-CX, Cisco IOSv, Cisco IOS-XE, Cumulus Linux or FRR as external BGP routers with netlab release 1.6.4, and I’m positive Jeroen van Bemmel will add Nokia SR Linux to that list.

If you’re not ready for a netlab upgrade, you can keep using Cumulus Linux as external BGP routers (I’ll explain the behind-the-scenes magic in another blog post, I’m at the Deep Conference this week).

For more details, read the updated BGP Labs Software Installation and Lab Setup guide.

Updating the IOS XE software and disabling the HTTP Server feature should prevent additional system exploits. But what of the systems that are already infected?

Notes from NANOG 89: Trust and Network Infrastructure

Trust is such a difficult concept in any context, and certainly computer networks are no exception. How can you be assured that your network infrastructure us running on authentic platforms, both hardware and software, and its operation has not been compromised in any way?

Notes from NANOG 89: BGP Error Handling

Distributed routing protocols rely on each active router processing routing updates in an identical manner. Given that there are so many implementation of the BGP routing protocol then the role of a clear standard specification is critical. This extends to the handling of error conditions. What happens when some implementations handle errors in a different manner to all the others?

Accelerate AWS Access with Arista

AWS Cloud WAN Tunnel-less Connect and Arista CloudEOS integrate to accelerate cloud onramp

As cloud and multicloud adoption continue to evolve, public cloud providers like AWS continue to introduce more and more tools for enterprise IT to choose from. For example, customers can deploy a virtual router in a Transit VPC and BGP peer with AWS Cloud WAN to interconnect on-premises networks and AWS VPCs. However, GRE or IPsec tunnels are often required for the BGP peering, adding up the network complexity and increasing operational costs.

Can enterprises trust the internet?

Dependency and trust have a complicated relationship, and that’s especially true with regard to enterprise views on networks. If you ask enterprise executives what network service has been the most transformational for their business, almost 100% will say “the internet.” If you ask them what network service has created the most problems for them, you get almost exactly the same response. The internet, they tell me, is insecure (87%), unreliable (81%), and lacks service quality (77%). And yet its loss would create “a major business disruption,” according to 97% of those users. Do you sense contradiction here? Well, we’re just getting started with that question.To read this article in full, please click here

Device42 adds cloud dependency mapping to IT discovery product

Device42 this week delivered hybrid cloud discovery capabilities for its IT inventory and asset management product, enabling IT managers to gain near real-time visibility into how cloud assets are communicating with other components and how they support business services across on-premises and cloud infrastructure.“[Customers] will have near real-time visibility across their entire hybrid IT footprint, regardless of the nature or the location of any IT asset, whether on-prem or in the cloud. This is big news for our industry that continues to rely on outdated spreadsheets to track things,” says Raj Jalan, CEO, Device42. “With cloud services and containers, the complexity and the growth are so massive that there isn’t clarity on the dependencies across the cloud, data centers, and on-premises.”To read this article in full, please click here

BrandPost: Reimagining the IT Experience with radical simplicity

Today’s enterprise networks are more challenging to manage than ever before. IT must support a complex mix of cloud-based and on-premises technologies, an explosion of third-party applications delivered in multiple ways, and new hybrid work models that must deliver the same seamless experience no matter where users happen to be.While IT professionals overwhelmingly value simplicity, they continue to struggle with ever-increasing levels of complexity. Disjointed systems, technology silos, fragmentation, lack of visibility, security threats, and time-consuming integrations—these and other factors get in the way of delivering consistent, unified experiences. Not surprisingly, they’re looking for a way to dramatically simplify their day-to-day operations.To read this article in full, please click here

Cache Rules go GA: precision control over every part of your cache

One year ago we introduced Cache Rules, a new way to customize cache settings on Cloudflare. Cache Rules provide greater flexibility for how users cache content, offering precise controls, a user-friendly API, and seamless Terraform integrations. Since it was released in late September 2022, over 100,000 websites have used Cache Rules to fine-tune their cache settings.

Today, we're thrilled to announce that Cache Rules, along with several other Rules products, are generally available (GA). But that’s not all — we're also introducing new configuration options for Cache Rules that provide even more options to customize how you cache on Cloudflare. These include functionality to define what resources are eligible for Cache Reserve, what timeout values should be respected when receiving data from your origin server, which custom ports we should use when we cache content, and whether we should bypass Cloudflare’s cache in the absence of a cache-control header.

Cache Rules give users full control and the ability to tailor their content delivery strategy for almost any use case, without needing to write code. As Cache Rules go GA, we are incredibly excited to see how fast customers can achieve their perfect cache strategy.

netlab 1.6.4: Support for Multi-Lab Projects; More BGP Goodies

Features in netlab release 1.6.4 were driven primarily by the needs of my BGP labs project:

bgp.session plugin (formerly known as ebgp.utils plugin) got support for BFD, passive BGP peers and remove-private-as option.
bgp.policy plugin implements basic BGP routing policy tools, including per-neighbor weights, local preference and MED.
You can enable external tools in user defaults and use default groups to create user- or project-wide groups in the defaults files.
Version-specific lab topology files allow netlab to select a lab topology that is a best fit for the netlab release you’re running.

Numerous platforms already support the new BGP nerd knobs:
