.Sh NAME
|
|
.Nm pim6dd.conf
|
|
.Nd "config file for pim6dd, PIM for IPv6 dense mode daemon"
|
|
.\"
|
|
.Sh DESCRIPTION
|
|
The file describes how the
|
|
.Nm pim6dd
|
|
daemon treats each interface on the system.
|
|
By default(including the case where there is no configuration file),
|
|
PIM will be activated on all interfaces, which can be overridden
|
|
by the file.
|
|
Lines beginning with
|
|
.Ql #
|
|
are comments.
|
|
.Pp
|
|
There are four types of configuration commands:
|
|
.Bl -tag -width Ds -compact
|
|
.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
|
|
.Nm
|
|
cannot reliably obtain preferences and metrics from the
|
|
unicast routing protocols, so a default value may be configured.
|
|
.\"
|
|
.It Ic default_source_metric Ar metric
|
|
Specifies a default metric value when sending a PIM assert message.
|
|
It is recommended that preferences be set such that metrics are never
|
|
consulted. However, default metrics may also be set and will default to
|
|
1024.
|
|
.\"
|
|
.It Xo
|
|
.Ic phyint Ar interface
|
|
.Op disable
|
|
.Xc
|
|
Specifies
|
|
.Nm
|
|
to ignore the interface even if the interface is multicast-capable.
|
|
Interfaces are specified in the form of "name unit", such as
|
|
.Ar gif0
|
|
and
|
|
.Ar ep1.
|
|

|
.It Xo
|
|
.Ic phyint Ar interface
|
|
.Op preference Ar preference
|
|
.Op metric Ar metric
|
|
.Xc
|
|
Specifies the preference and/or metric values when sending a PIM
|
|
assert message on the interface.
|
|
.\"
|
|
.It Xo
|
|
.Ic filter Ar groupaddrs Ar interfaces...
|
|
.Xc
|
|
Specifies an output filter. If an incoming multicast packet's destination
|
|
matches the specified
|
|
.Ar groupaddrs,
|
|
the packet is not sent on the
|
|
.Ar interfaces.
|
|
Moreover, if there is no other interface than the specified
|
|
interfaces,
|
|
.Nm pim6dd
|
|
sends a prune message to the upstream neighbor.
|
|
Valid formats of
|
|
.Ar groupaddrs
|
|
are as follows.
|
|
.Bl -tag -width Ds -compact
|
|
.It Ar multicastaddr1-multicastaddr2
|
|
specifies a numerical range of a scope.
|
|
Multicast addresses
|
|
from
|
|
.Ar multicastaddr1
|
|
to
|
|
.Ar multicastaddr2
|
|
will be filtered out.
|
|
Note that neither a white space nor a tab character must not be
|
|
inserted before nor after
|
|
.Ql - .
|
|
.It Ar multicastaddr/prefixlen
|
|
specifies a group prefix of a scope.
|
|
Multicast addresses which match the specified prefix will be filtered
|
|
out.
|
|
If
|
|
.Ar prefixlen
|
|
is omitted, it means the exact match for
|
|
.Ar multicastaddr.
|
|
.El
|
|
.Ar interfaces
|
|
are specified as a blank separated list of interfaces. Each interface is
|
|
specified in the form of "name unit".

.Sh HISTORY
|
|
The
|
|
.Nm pim6dd
|
|
command and the configuration file
|
|
.Nm
|
|
are based on
|
|
.Nm pimdd,
|
|
which is an IPv4 multicast routing daemon
|
|
developed at the University of Oregon.
|
|
.Nm Pimdd
|
|
has been derived from PIM sparse-mode
|
|
.Nm pimd
|
|
developed at University of Southern California.
|
|
Part of these two programs above has also been derived from
|
|
.Nm mrouted.
