VyOS 2026.02

VyOS Stream 2026.02 is available for download now. It features multiple backports from the rolling release, including TLS support for syslog, NAT66 source groups, IPFIX support in VPP, FRR and VPP updates, and over fifty bug fixes. It also makes the VPP configuration subsystem use DPDK as the default driver for NICs that support it and fall back to XDP automatically if needed — there is no need to and no option to configure the driver by hand anymore. VyOS no longer allows multicast addresses to be assigned to interfaces. Previously, something like set interfaces ethernet eth0 address 224.0.0.100/24 was a valid configuration commands. Now the CLI will reject it and configs with such addresses will fail to load. While Linux kernel and iproute2 allow manually assigning multicast addresses, allowing that in the VyOS CLI was an oversight - such configurations will never work for their intended purposes. For multicast traffic to actually work, hosts need to join multicast groups using IGMP. Official announcement Download VyOS
