Welcome ldpd, the Label Distribution Protocol daemon.

Built using the imsg/three process framework, its main aim
is to redistribute MPLS labels between peers.

Right now it has some really basic functionalities,
the basic protocol works and peers are able to exchange
labels and insert them in the kernel.
It still does not react to changes of topology.

Not yet connected to the builds.

+.Sh NAME
+.Nm ldpd.conf
+.Nd Label Distribution Protocol daemon configuration file
+.Sh DESCRIPTION
+The
+.Xr ldpd 8
+daemon implements the Label Distribution Protocol as described in RFC 3036.
+.Sh SECTIONS
+The
+.Nm
+config file is divided into three main sections.
+.Bl -tag -width xxxx
+.It Sy Macros
+User-defined variables may be defined and used later, simplifying the
+configuration file.
+.It Sy Global Configuration
+Global settings for
+.Xr ldpd 8 .
+.It Sy Interfaces Configuration
+Interface-specific parameters.
+.El
+.Sh MACROS
+Much like
+.Xr cpp 1
+or
+.Xr m4 1 ,
+macros can be defined that will later be expanded in context.
+Macro names must start with a letter, and may contain letters, digits,
+and underscores.
+Macro names may not be reserved words (for example,
+.Ic cost ) .
+Macros are not expanded inside quotes.
+.Pp
+For example:
+.Bd -literal -offset indent
+hi="2"
+interface em0 {
+	cost $hi
+}
+.Ed
+.Sh GLOBAL CONFIGURATION
+Global settings concerns the main behaviour of the daemon.
+.Pp
+.Bl -tag -width Ds -compact

+.Ic fib-update
+.Pq Ic yes Ns \&| Ns Ic no
+.Xc
+If set to
+.Ic no ,
+do not update the Forwarding Information Base, a.k.a. the kernel routing
+table.
+The default is
+.Ic yes .
+.Pp
+.It Xo

+.Xc
+If set to
+.Ic connected ,
+routes to directly attached networks will be
+announced over RIP.
+If set to
+.Ic static ,
+static routes will be announced over RIP.
+If set to
+.Ic default ,
+a default route pointing to this router will be announced over RIP.
+It is possible to specify a network range with
+.Ar prefix ;
+networks need to be part of that range to be redistributed.
+Additionally it is possible to redistribute based on route labels
+using the
+.Ic rtlabel
+keyword.
+By default no additional routes will be announced over RIP.
+.Pp
+.Ic redistribute
+statements are evaluated in sequential order, from first to last.
+The first matching rule decides if a route should be redistributed or not.
+Matching rules starting with
+.Ic no
+will force the route to be not announced.
+.Pp
+.It Xo
+.Ic split-horizon

+If set to
+.Ic default ,
+do not redistribute routes to the interface from which they were learned.
+If set to
+.Ic poisoned ,
+redistribute routes to the interface from which they were learned, by
+forcing the metric to infinity.
+Both these behaviours can resolve routing loops when a router goes down.
+The default is
+.Ic none .
+.Pp
+.It Xo
+.Ic triggered-updates
+.Pq Ic yes Ns \&| Ns Ic no
+.Xc
+Immediately trigger responses when a route changes.
+The default is
+.Ic yes .
+.El
+.Sh INTERFACES
+Each interface can have several parameters configured individually, otherwise
+they are inherited.

+Interface-specific parameters are listed below.
+.Bl -tag -width Ds
+.It Ic auth-key Ar key
+Set the authentication key for
+.Ic simple
+authentication.
+Up to 16 characters can be specified.
+.It Ic auth-md Ar key-id key
+Set the authentication
+.Ar key-id
+and
+.Ar key
+for
+.Ic crypt
+authentication.
+The valid range for
+.Ar key-id
+is 0\-255.
+Up to 16 characters can be specified for
+.Ar key .
+Multiple keys may be specified.
+.It Ic auth-md-keyid Ar key-id
+Configure the
+.Ar key-id
+to use for
+.Ic crypt
+authentication.
+The valid range for
+.Ar key-id
+is 0\-255.
+The default key-id is 1.
+.It Xo
+.Ic auth-type
+.Po Ic none Ns \&| Ns
+.Ic simple Ns \&| Ns Ic crypt Pc
+.Xc
+Set the authentication type.
+The default is
+.Ic none .
+Simple authentication uses a plaintext password, up to 16 characters.
+Crypt authentication uses an MD5 hash.
+.It Ic cost Ar number
+Cost of the network connected through this interface.
+Values must be between 1 and 16, inclusive.
+.It Ic demote Ar group
+Increase the
+.Xr carp 4
+demotion counter by 1 on the given interface group, usually
+.Ar carp ,
+when the interface state is going down.
+The demotion counter will be decreased when the interface
+state is active again.
+.It Ic passive
+Prevent transmission and reception of LDP packets on this interface.
