.Sh NAME
.Nm ldpd
.Nd Label Distribution Protocol (LDP) routing daemon
.Sh SYNOPSIS
.Nm
.Op Fl dnv
.Op Fl D Ar macro Ns = Ns Ar value
.Op Fl f Ar file
.Op Fl s Ar socket
.Sh DESCRIPTION
.Nm
is the Label Distribution Protocol
.Pq LDP
daemon, which distributes MPLS label mappings between routers.
.Pp
A running
.Nm
can be controlled with the
.Xr ldpctl 8
utility.
.Pp
The options are as follows:
.Bl -tag -width Ds
.It Fl D Ar macro Ns = Ns Ar value
Define
.Ar macro
to be set to
.Ar value
on the command line.
Overrides the definition of
.Ar macro
in the configuration file.
.It Fl d
Do not daemonize.
If this option is specified,
.Nm
will run in the foreground and log to
.Em stderr .
.It Fl f Ar file
Specify an alternative configuration file.
.It Fl n
Configtest mode.
Only check the configuration file for validity.
.It Fl s Ar socket
Use an alternate location for the default control socket.
.It Fl v
Produce more verbose output.
.El
.Sh FILES
.Bl -tag -width "/var/run/ldpd.sockXX" -compact
.It Pa /etc/ldpd.conf
Default
.Nm
