Ifupdown-ng is a network device manager that is largely compatible with Debian ifupdown, BusyBox ifupdown and Cumulus Networks' ifupdown2.

It is intended as a drop-in replacement for all aforementioned suites and provides the well-known ifup/ifdown/ifquery tools as well as ifctrstat to query interface statistics via CLI.

ifupdown-ng provides dependecy resolutions between interfaces (physical, bond, vlan, bridges, etc.) to configure interfaces in a meaniful order independent of their order within the configuration file(s).

ifupdown-ng currently has support for B.A.T.M.A.N. adv., bonding, bridges, MPLS, PPP, regular tunnels + wireguard, VLANs, VRFs, VXLAN, as well as setting hardware/driver parameters with ethtool.
