NAME

ldpd — Label Distribution Protocol daemon

SYNOPSIS

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).
