|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl DdfhW
|
|
.Op Fl p Ar port
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
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
|
|
.Nm .
|
|
Also this is the current measure used to filter neighbours.
|
|
You should see some logs reported via
|
|
.Xr syslog 3
|
|
interface.
|
|
.Pp
|
|
You can increase the log verbosity using the
|
|
.Fl W
|
|
and
|
|
.Fl 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 password.
|
|
.Pp
|
|
.Nm
|
|
computes existing routes and tries to match them on MPLS labels
|
|
announced by other LDP peers.
|
|
This means that
|
|
.Dq normal
|
|
routes will be changed into tagged routes, and MPLS routing table
|
|
will be populated.
|
|
It will also announce its mappings to its peers.
|
|
.Nm
|
|
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.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width 15n
|
|
.It Fl D
|
|
Enable debug mode.
|
|
.It Fl d
|
|
Don't use route interception code.
|
|
.It Fl f
|
|
Run in foreground.
|
|
Use STDOUT for warning and debug messages.
|
|
.It Fl h
|
|
Outputs supported flags.
|
|
.It Fl p Ar port
|
|
Changes the TCP control port (default: 2626).
|
|
.It Fl W
|
|
Enable output of warning messages.
