LDPD.CONF(5) OpenBSD Programmer's Manual LDPD.CONF(5)NAMEldpd.conf - Label Distribution Protocol daemon configuration file
DESCRIPTION
The ldpd(8) daemon implements the Label Distribution Protocol as
described in RFC 3036.
SECTIONS
The ldpd.conf config file is divided into three main sections.
Macros
User-defined variables may be defined and used later, simplifying
the configuration file.
Global Configuration
Global settings for ldpd(8).
Interfaces Configuration
Interface-specific parameters.
MACROS
Much like cpp(1) or 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, cost). Macros are not expanded inside
quotes.
For example:
hi="2"
interface em0 {
cost $hi
}
GLOBAL CONFIGURATION
Global settings concerns the main behaviour of the daemon.
fib-update (yes|no)
If set to no, do not update the Label Forwarding Information
Base, a.k.a. the kernel routing table. The default is yes.
router-id address
Set the router ID; in combination with labelspace it forms the
LSR-ID.
labelspace number
Set the label space advertised by ldpd(8).
holdtime seconds
Set the hello holdtime in seconds. The maximum time ldpd(8) will
wait between two consecutive hello messages from a peer before it
is marked as being down. The default value is 15.
hello-interval seconds
Set the hello interval in seconds. The default value is 5; valid
range is 1-65535.
keepalive seconds
Set the keepalive interval in seconds. The default value is 180;
valid range is 1-65535.
distribution (independent|ordered)
Select the distribution mode. independent distributes labels at
any time; ordered forces ldpd(8) to wait a mapping from nexthop
before distributing it to peers.
retention (liberal|conservative)
Select the retention mode. conservative retains just the labels
advertised from nexthop; liberal mode retains every label
received, even those not advertised from nexthops.
advertisement (unsolicited|ondemand)
Select the advertisement mode. unsolicited advertises labels
according to the distribution mode; ondemand advertises labels
solely upon explicit request from peers.
INTERFACES
Each interface can have several parameters configured individually,
otherwise they are inherited.
interface em0 {
}
Interface-specific parameters are listed below.
passive
Prevent transmission and reception of LDP packets on this
interface.
