Each episode opens with a recent network outage, a peering dispute, or a routing-table anomaly — then traces the engineering decisions and business incentives behind it. Lucas maps the technical architecture (BGP, MPLS, IXPs), while Luna pushes on the economics: who pays for undersea cables, why ISPs throttle certain traffic, and how network neutrality shapes startup access. They analyze real incidents — AWS’s Tokyo region failure, a Level 3 vs. Cogent peering war, or the latency impact of a new data-center route — and explain what network engineers actually debate in NANOG meetings. This is not a ‘how the internet works’ primer; it’s the layer-3 view for professionals who manage, build, or invest in network infrastructure. Expect granular discussions of dark fiber, CDN caching strategies, and the politics of IP address allocation. By the end, you’ll see the internet as a finite, fragile, and fiercely competitive topology — and understand why a single undersea cable cut can reset stock prices. #InternetInfrastructure #NetworkEngineering…","last_synced_at":"2026-07-18T22:19:10.157593+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928"},"episode":{"title":"How EVPN-VXLAN Is Replacing Traditional VLANs in Data Centers","slug":"how-evpn-vxlan-is-replacing-traditional-vlans-in-data-centers","published_at":"2026-07-18T09:55:48+00:00","page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-evpn-vxlan-is-replacing-traditional-vlans-in-data-centers","show_page_url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928","url":"https://audio.fexingo.com/business/networking-tech/episode-0118.mp3","audio_url":"https://audio.fexingo.com/business/networking-tech/episode-0118.mp3","summary":"Episode 118 of Networking Tech with Fexingo dives into the quiet revolution happening inside modern data centers: the shift from traditional VLANs to EVPN-VXLAN. Lucas and Luna break down why the old 12-bit VLAN ID is hitting a wall at 4094 networks, and how VXLAN expands that to 16 million virtual networks using UDP encapsulation. They walk through a real-world example at a major cloud provider that migrated a multi-tenant environment from VLANs to EVPN-VXLAN, cutting provisioning time from days to minutes and eliminating spanning-tree headaches. Listeners learn how MP-BGP and Type 2 routes enable MAC address learning across Layer 3 underlays, why ARP suppression reduces broadcast noise, and what it means for network engineers today. If you design, build, or manage data center networks, this episode gives you the concrete rationale and deployment patterns behind the biggest under-the-hood change in data center networking since leaf-spine architectures. #EVPNVXLAN #VXLAN #DataCenterNetworking #VLAN #NetworkEngineering #MPBGP #LeafSpine #NetworkVirtualization #OverlayNetworking #NetworkAutomation #CloudNetworking #Technology #ITInfrastructure #Networking #FexingoBusiness #BusinessPodcast #TechPodcast #SoftwareDefinedNetworking Keep every episode free: buymeacoffee.com/fexingo","meta_description":"Episode 118 of Networking Tech with Fexingo dives into the quiet revolution happening inside modern data centers: the shift from traditional VLANs to EVPN…","key_points":[],"chapters":[],"topics":[],"duration_seconds":548,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/episodes/how-evpn-vxlan-is-replacing-traditional-vlans-in-data-centers/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/networking-tech-with-fexingo-internet-infrastructure-routing-and-network-engineering-7871928/how-evpn-vxlan-is-replacing-traditional-vlans-in-data-centers.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
