LDPD(8)                 NetBSD System Manager's Manual                 LDPD(8)


NAME

     ldpd -- Label Distribution Protocol Daemon


SYNOPSIS

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


DESCRIPTION

     ldpd is a utility used to automatically distribute labels between two
     MPLS LSRs almost conforming 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) interface.

     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 protocol, neighbours etc. but also to set
     runtime parameters.  The required password is the same as the root pass-
     word.

     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 routing 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 protocol 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.

HISTORY

     The ldpd command appeared in NetBSD 6.0.


BUGS

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