This is the development branch for version 1.0 of ndppd.
Please read the manpages ndppd.conf.5 and ndppd.8.
ndppd was rewritten from scratch using C (C99).
It's currently highly experimental, but I expect a beta to be ready by the end of the year.
ndppd, or NDP Proxy Daemon, is a daemon that proxies neighbor discovery messages. It listens for neighbor solicitations on a specified interface and responds with neighbor advertisements - as described in RFC 4861 (section 7.2).
There are several methods available when determining of a neighbor advertisement should be sent back:
The first method, and the most common, is the autoresolve method. It uses the routing table to determine how the target is reachable. If a valid route exists, a neighbor solicitation is sent out through that interface. Only once ndppd receives a neighbor advertisement from the target will it start responding to neighbor solicitations.
The second method is the explicit method. A neighbor solicitation is sent through a manually provided interface. This method also allows for the use of autowire which sets up a route to the specified target through said interface if the target was found, and for the duration of the session.
The third method is the static method. When used, ndppd will immediately respond to neighbor solicitation messages immediately without first querying an internal interface.
You must have asciidoctor installed in order to transpile the documentation.
In most cases, the following should be sufficient:
make all && make install
