LDPD(8)

NAME
ldpd - Label Distribution Protocol daemon

SYNOPSIS
ldpd [-dnv] [-D macro=value] [-f file] [-s socket]

DESCRIPTION
ldpd is the Label Distribution Protocol (LDP) daemon, which distributes MPLS label mappings between routers.

A running ldpd can be controlled with the ldpctl(8) utility.

The options are as follows:

-D macro=value
    Define macro to be set to value on the command line. Overrides the definition of macro in the configuration file.

-d  Do not daemonize. If this option is specified, ldpd will run in the foreground and log to stderr.

-f file
    Specify an alternative configuration file.

-n  Configtest mode. Only check the configuration file for validity.

-s socket
    Use an alternate location for the default control socket.

-v  Produce more verbose output.

FILES
/etc/ldpd.conf
    Default ldpd configuration file.
/var/run/ldpd.sock
    UNIX-domain socket used for communication with ldpctl(8).
