RouterOS ZeroTier

RouterOS uses /zerotier instances and interfaces rather than the Linux zerotier-cli. This skill covers the native package and its controller role. The original lab used arm64 CHR 7.25; its reported results and the limits of that evidence are recorded in Grounding.[^lab]

Package and device-mode

• Install the zerotier extra package matching the router's version and architecture, then reboot. See Extra packages.[^docs]
• The native package supports ARM/ARM64. For a CHR lab, use arm64: the official 7.25 arm64 archive contains zerotier-7.25-arm64.npk; the x86 archive has no ZeroTier package. This distinction was independently rechecked during review.[^packages]
• Check /system/device-mode/print for zerotier: yes before configuring it. If blocked, follow the device-mode procedure, including any required physical confirmation.[^docs]
