NetBSD 6.1.5 - man page for ldpd (netbsd section 8)

     ldpd -- Label Distribution Protocol Daemon

     ldpd [-DdfhW] [-c config_file] [-p port]

     ldpd is a utility used to automatically distribute labels between two MPLS LSRs almost con-
     forming to RFC3036.  Right now it is in BETA stage and many features are not implemented or
     may not work.  As a security measure you SHOULD filter the LDP well-known (646) TCP and UDP
     ports using your favourite packet filter before starting ldpd.  Also this is the current
     measure used to filter neighbours.  You should see some logs reported via syslog(3) inter-

     You can increase the log verbosity using the -W and -D flags.  Also you can telnet to the
     control port (default: 2626) and use this interface in order to get informations about pro-
     tocol, neighbours etc. but also to set runtime parameters.  The required password is the
     same as the root password.

     ldpd computes existing routes and tries to match them on MPLS labels announced by other LDP
     peers.  This means that ``normal'' routes will be changed into tagged routes, and MPLS rout-
     ing table will be populated.  It will also announce its mappings to its peers.  ldpd will
     listen on a route socket and compute the necessary changes in order to change untagged
     routes into tagged routes.  This means that one may use one's favourite dynamic routing pro-
     tocol daemon without modifications.

     The options are as follows:

     -c config_file   Specifies a path to the config file.  Default: /etc/ldpd.conf - see
		      ldpd.conf(5) for configuration file format.

     -D 	      Enable debug mode.

     -d 	      Don't use route interception code.

     -f 	      Run in foreground.  Use STDOUT for warning and debug messages.

     -h 	      Outputs supported flags.

     -p port	      Changes the TCP control port (default: 2626).

     -W 	      Enable output of warning messages.

     LDP Specification, RFC, 3036, January 2001.

     LDP Applicability, RFC, 3037, January 2001.

     The ldpd command appeared in NetBSD 6.0.

     ldpd supports only IPv4 and doesn't implement Path Vector and Hop Count TLVs.
