.Nm pim6sd.conf
|
|
.Nd config file for pim6sd, PIM-SM daemon for IPv6
|
|
.\"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
configuration file consists of a sequence of statements terminated
|
|
by a semi-colon (`;'), each of which specifies how the daemon treats
|
|
each interface on the system, specifies some parameters of the PIM
|
|
protocol, and requires some special behavior defined by the protocol.
|
|
.Pp
|
|
Each statement can be constructed by multiple lines.
|
|
.Pp
|
|
Lines beginning with
|
|
.Ql #
|
|
are comments.
|
|
.\".Pp
|
|
.\"Note that
|
|
.\".Xr pim6sd 8
|
|
.\"works even without the configuration file, although the daemon
|
|
.\"will warn that there is no configuration file.
|
|
.\"In such a case, the daemon will automatically set the default value
|
|
.\"to each configurable parameter.
|
|
.\"
|
|
.Pp
|
|
The following statements can be specified in the configuration file.
|
|
.Pp
|
|
.Bl -tag -width Ds -compact
|
|
.It Xo
|
|
.Ic log
|
|
.Ar option...
|
|
.Ic ;
|
|
.Xc
|
|
Specify debug messages to be printed out. Each
|
|
.Ar option
|
|
usually specifies a subset of the messages to be printed.
|
|
If an
|
|
.Ar option
|
|
begins with
|
|
.Ic no ,
|
|
it means that the set of the messages that are specified by the option
|
|
will not be printed. For example,
|
|
.Ic `all nomld'
|
|
means that all the messages except MLD related ones will be printed.
|
|
Valid options are
|
|
.Ic mld_proto, mld_timer, mld_member, mld, switch, trace, mtrace, traceroute,
|
|
.Ic timeout, callout, pkt, packets, interfaces, vif, kernel, cache, mfc,
|
|
.Ic k_cache, k_mfc, rsrr, pim_detail, pim_hello, pim_neighbors, pim_register,
|

.Ic registers, pim_join_prune, pim_j_p, pim_jp, pim_bootstrap, pim_bsr, bsr,

.Ic bootstrap, pim_asserts, pim_cand_rp, pim_c_rp, pim_rp, rp, pim_routes,

.Ic all .

.It Xo

.Ic reverselookup (yes \(ba no);
|
|
.Xc
|
|
Specifies if a hostname for an IPv6 address should be resolved
|
|
on logging.
|
|
.Ic yes
|
|
means a hostname should be resolved, and
|
|
.Ic no
|
|
means should not.
|
|
By default, a hostname is not resolved.

|
|
.It Xo

.Ic phyint Ar interface

.Ic ;
|

.Xc
|
|
Specifies
|
|
.Xr pim6sd 8
|
|
to ignore the interface even if the interface is multicast-capable.
|
|
Note that PIM will be activated on all interfaces by default.
|
|
Interfaces are specified in the form of "name unit", such as
|
|
.Ar gif0
|
|
and
|
|
.Ar ep1.

.Op preference Ar preference

|
|
.Ic ;
|
|
.Xc
|
|
Specifies the preference and/or metric values when sending a PIM
|
|
assert message on the interface.
|
|
If another optional parameter
|
|
.Ic nolistener
|
|
is specified,
|
|
.Xr pim6sd 8
|
|
will not send any MLD packets on the interface.
|
|
This option is usually meaningless but will be useful when
|
|
MLD messages are noisy (e.g. when debugging) and there is surely no
|
|
listner on the interface.
|
|
.\"
|
|
.It Xo
|
|
.Ic default_source_preference Ar preference;
|
|
.Xc
|
|
Specifies a default preference value when sending a PIM assert message.
|
|
Preferences are used by assert elections to determine upstream routers.
|
|
Currently
|
|
.Xr pim6sd 8
|
|
does not have an effective method to obtain preferences and metrics from the
|
|
unicast routing protocols, so you may want to set a default value by hand.
|
|
The default preference is 1024.
|
|
.\"
|
|
.It Ic default_source_metric Ar metric;
|
|
Specifies a default metric value when sending a PIM assert message.
|
|
Since
|
|
.Xr pim6sd 8
|
|
cannot get an effective metric of unicast routing,
|
|
it is recommended that preferences is set such that metrics are never
|
|
consulted. However, default metrics may also be set, and
|
|
its default value is 1024.

is the coefficient to determine the hello holdtime;
|
|
the holdtime will be
|
|
.Ar period
|
|

|
|
.Ar coef .
|
|
The default values of the period and the coefficient are 30 and 3.5,
|
|
respectively. The default holdtime is 105 seconds as a result.

specifies the period in second between 2 join/prune messages.

is the coefficient to determine the join/prune holdtime;

the holdtime will be

The default values of the period and the coefficient are 60 and 3.5,
