.Nd PIM for IPv6 dense mode daemon
.Sh SYNOPSIS

.Op Fl c Ar configfile
.Op Fl d Op debug_level Op ,debug_level
.Sh DESCRIPTION
.Nm Pim6dd
is an IPv6 multicast routing daemon, which supports
PIMv2(Protocol Independent Multicast Version 2) dense mode
for IPv6.
.Pp
Options supported by
.Nm :
.Bl -tag -width Ds
.It Fl c Ar configfile
Specify alternate location,
.Ar configfile ,
for configuration file.
By default,
.Pa /etc/pim6dd.conf
is used.
.It Fl d
Specify debug levels. If this option is specified without any arguments,
all debug messages will be printed out.
A subset of the messages to be printed out can be specified
as arguments of the option.
Valid debug levels are
.Ic timeout, packets, interfaces, kernel, mfc, pim_detail, pim_hello,
.Ic kernel, mfc, pim_detail, pim_hello, pim_jp, pim_graft, pim_asserts,
.Ic pim_routes, pim_timers, rpf, pim, routes, routers, timers,
and
.Ic asserts.
.El
.Pp
.Nm Pim6dd
automatically configures itself to forward on all multicast-capable
interfaces, i.e., interfaces that have the IFF_MULTICAST flag set (excluding
the "loopback interface").
To override the default configuration,
configuration commands may be placed in
.Pa /etc/pim6dd.conf
2000-05-04 17:42:03 +00:00
.Po
or an alternative file, specified by the
.Sq Fl c
option
.Pc .

.Sh FILES
.Bl -tag -width /etc/pim6dd.conf -compact
.It Pa /etc/pim6dd.conf
The default configuration file.

.Xr pim6dd.conf 5
.Sh HISTORY
The
.Nm
command is 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 .
.Nm Mrouted
is COPYRIGHT 1989 by The Board of Trustees of
Leland Stanford Junior University.
.\"
.Sh BUGS
.Nm Pim6dd
does not contain any unicast routing engine, so a unicast routing
daemon needs to run on the system.
.Pp
The kernel unicast routing table is periodically polled by
.Nm
in order to follow changes of existing unicast routes.
.Pp
.Nm
must be used on an IPv6 router.
Be sure to set
.Li net.inet6.ip6.forwarding
variable to 1 with
.Xr sysctl 8 .
