IO::Socket::Netlink::Route - Object interface to NETLINK_ROUTE netlink protocol sockets
This subclass of IO::Socket::Netlink implements the NETLINK_ROUTE protocol. This protocol allows communication with the Linux kernel's networking stack, allowing querying or modification of interfaces, addresses, routes, and other networking properties.
This module is currently a work-in-progress, and this documentation is fairly minimal. The reader is expected to be familiar with NETLINK_ROUTE, as it currently only gives a fairly minimal description of the Perl-level wrapping of the kernel level concepts. For more information see the documentation in rtnetlink(7).
Each message type falls into one of the following subclasses, chosen by the value of the nlmsg_type field. Each subclass provides access to the field headers of its message body, and netlink attributes.
