.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 Ns :
|
|
.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.

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
|
|

|
|
or an alternative file, specified by the

.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 .

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 .
