BGP Route Reflector – RR vs Confederation is one of the first things Network Engineers would like to understand when they learn both of these Internal BGP scalability mechanisms. For those who don’t know the basics of these mechanisms, please read BGP Route Reflector in Plain English and BGP Confederation Blog posts from the website first.
There are many differences when we compare Confederation vs Route Reflector and in this post, some of the items in the comparison chart will be explained.
Both of these techniques are used in Internal BGP for scalability purposes. But BGP RR changes the Full Mesh IBGP topologies to the Hub and Spoke. BGP confederation divides the Autonomous System into the sub-ASes but inside every Sub-AS, IBGP rules are applied.
Inside BGP Sub Autonomous System, full Mesh IBGP or Route Reflector is used. So, we consider BGP RR compare to Confederation to be more scalable because inside Sub-AS still full-mesh IBGP might be used.
If RR inside Sub-AS is deployed, then configuration complexity would increase.

At Cloudflare, we are on a mission to help build a better Internet. We continue to grow our network, and it is important for us to do so responsibly.
Since Earth Day 2021, some pieces of this effort have included:
And we are just getting started. We are working to make the Cloudflare network — and our customers’ websites, applications, and networks — as efficient as possible in terms of design, hardware, systems, and protocols. After all, we do not want to lose sight of our responsibilities to our home: our planet Earth.
During Impact Week last year, we began testing Green Compute in a closed beta. Green Compute makes Workers Cron Triggers run only in facilities that are powered by renewable energy. We are hoping to incentivize more facilities to implement responsible climate and energy policies.
With Green Compute enabled, Workers Cron Triggers will run Continue reading
In this post, we will compare BGP and EIGRP. We will look at some of the important aspects when we compare BGP vs EIGRP. Although EIGRP is used as an IGP and BGP is used mainly as an External routing protocol, we will compare from many different design aspects. Also, BGP can be used as an Internal IGP protocol as well and we will take that into consideration as well.
We prepared the above comparison chart for BGP vs EIGRP comparison. We will look at some of those important Comparison criteria from a design point of view.
One of the biggest reasons we choose BGP, not EIGRP is Scalability. BGP is used as a Global Internet routing protocol and as of 2022, the Global routing table size for IPv4 unicast prefixes is around 900 000. So almost a million prefixes we carry over BGP on the Internet.
So, proven scalability for BGP we can say. EIGRP usually can carry only a couple of thousands of prefixes, this is one of the reasons, EIGRPrp is used as an Internal dynamic routing protocol, not over the Internet.
Pods are a basic building block of any Kubernetes-based deployment… but what exactly are they and how are they related to Kubernetes networking? Stuart Charlton unraveled that mystery in the Understanding Pods video (part of Kubernetes Networking Deep Dive webinar)

The FR Routing project is a fully featured open-source routing stack, including BGP, OSPF, and IS-Is (among others), supported by a community including NVDIA, Orange, VMWare, and many others. On today’s episode of the Hedge, Tom Ammon and Russ White are joined by Donald Sharp, Alistair Woodman, and Quentin Young to update listeners on projects completed and underway in FR Routing.

In this episode of IPv6 Buzz we talk about what a Proof of Concept (PoC) lab is and why you probably need one as part of your IPv6 initiative. We discuss technical challenges and considerations, how much of your production network you need to model, learning opportunities that come with a lab, and more.

My second post on privacy for network engineers is up over at Packet Pushers—
WPA3, the latest Wi-Fi security suite, is finally making its way into products around the world. Here’s what you need to know for using it at home and in enterprise networks. What Is WPA? Wi-Fi Protected Access (WPA) is the suite of standards that define security for both WPA-Personal (passphrase) and WPA-Enterprise (802.1X) based wireless […]
