Manipulating the Networking Environment Using RTNETLINK
RTNETLINK is a simple, yet versatile way of manipulating the networking environment of a Linux host. User-space network protocol handlers are ideal candidates for using RTNETLINK. The advanced IP routing command suite, referred to as IPROUTE2, is based on RTNETLINK. More information about the different operations and flags of RTNETLINK can be found at NETLINK(7) and RTNETLINK(7).
