Linux Server VLAN Tagging with systemd-networkd

Episode 78 of Linux Server Admin with Fexingo dives into VLAN tagging on Linux servers using systemd-networkd. Lucas and Luna walk through a real-world scenario: a multi-tenant web host needing to isolate customer traffic without buying new hardware. They explain how to configure 802.1Q VLANs on a single physical interface, assign IPs, and verify connectivity — all with systemd-networkd's clean .network and .netdev files. No more legacy ifcfg scripts or manual vconfig commands. By the end, you'll know how to carve a single NIC into multiple logical networks in under ten minutes.
