Namex, an Italian IXP, decided to replace their existing peering fabric with a fully automated leaf-and-spine fabric using VXLAN and EVPN running on Cumulus Linux.
They documented the design, deployment process, and automation scripts they developed in an extensive blog post that’s well worth reading. Enjoy ;)
Multi-Chassis Link Aggregation Group or MLAG is an idea that’s been around for a while.
It allows for the ability to form LACP channels across multiple physical switches.
Wikipedia shows a few different topology examples here
Vendor implementations are proprietary but the idea of MLAG was first mentioned in 802.1AX-2008 in 2008.
It first started to become popular in data center networking in the late 2000s
What makes the addition of MLAG to MikroTik’s RouterOS feature set notable is that it lowers the barrier to entry for this particular feature.
CRS 3xx switches are very inexpensive (starting at $149 USD) and may very well be the lowest cost MLAG capable hardware available on the market.
MLAG has been asked for by the MikroTik community a number of times and the most active feature request thread started here in 2020:
new feature request MLAG!!! – MikroTik
MikroTik added several version 7 beta releases in 2021 and included MLAG for all CRS 3xx series switches in 7.1beta6 on May 18th, 2021.
MLAG is fairly consistent across vendors with the need Continue reading
On today's Heavy Networking, we get practical with infrastructure-as-code, talking with sponsor Gluware about how their users have integrated network automation into their IT practices, bringing DevOps to NetOps. We also explore Gluware Lab, an IDE for network engineers can develop network features and workflows. Our guests are Olivier Huynh Van, Chief Science Officer and Co-Founder; and Michael Haugh, VP of Product Marketing.

Over the past year, Cloudflare Gateway has grown from a DNS filtering solution to a Secure Web Gateway. That growth has allowed customers to protect their organizations with fine-grained identity-based HTTP policies and malware protection wherever their users are. But what about other Internet-bound, non-HTTP traffic that users generate every day — like SSH?
Today we’re excited to announce the ability for administrators to configure network-based policies in Cloudflare Gateway. Like DNS and HTTP policy enforcement, organizations can use network selectors like IP address and port to control access to any network origin.
Because Cloudflare for Teams integrates with your identity provider, it also gives you the ability to create identity-based network policies. This means you can now control access to non-HTTP resources on a per-user basis regardless of where they are or what device they’re accessing that resource from.
A major goal for Cloudflare One is to expand the number of on-ramps to Cloudflare — just send your traffic to our edge however you wish and we’ll make sure it gets to the destination as quickly and securely as possible. We released Magic WAN and Magic Firewall to let administrators replace MPLS connections, define routing decisions, and apply packet-based Continue reading
By now you’ve seen the news that longtime CEO of Aruba Keerti Melkote is retiring. He’s decided that his 20-year journey has come to a conclusion and he is stepping down into an advisory role until the end of the HPE fiscal year on October 31, 2021. Leaving along with him are CTO Partha Narasimhan and Chief Architect Pradeep Iyer. It’s a big shift in the way that things will be done going forward for Aruba. There are already plenty of hot takes out there about how this is going to be good or bad for Aruba and for HPE depending on which source you want to read. Because I just couldn’t resist I’m going to take a stab at it too.
Keerti is a great person. He’s smart and capable and has always surrounded himself with good people as well. The HPE acquisition honestly couldn’t have gone any better for him and his team. The term “reverse acquisition” gets used a lot and I think this is one of the few positive examples of it. Aruba became the networking division of HPE. They rebuilt the husk that was HP’s campus networking division and expanded it Continue reading

In the final video in his Cisco SD-WAN webinar, David Penaloza discusses site ID assignments and policy processing order.
A carefully planned site scheme and ordered list of policy entries will save you complications and headaches when deploying the SD-WAN solution.
