NAME

     pim6dd.conf - config file for pim6dd, PIM for IPv6 dense mode daemon


DESCRIPTION

     The file describes how the pim6dd(8) 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 `#' are comments.

     The following configuration directives are availble:

     default_source_preference preference
             Specifies a default preference value when sending a PIM assert
             message.  Preferences are used by assert elections to determine
             upstream routers.  Currently pim6dd(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.
     default_source_metric metric
             Specifies a default metric value when sending a PIM assert
             message.  Since pim6dd(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.
     phyint interface [disable]
             Specifies pim6dd(8) to ignore the interface even if the interface
             is multicast-capable.  Interfaces are specified in the form of
             "name unit", such as gif0 and ep1.
     phyint interface [preference preference] [metric metric]
             Specifies the preference and/or metric values when sending a PIM
             assert message on the interface.
     filter groupaddrs interfaces...
             Specifies an output filter by defining an administrative scope.
             If an incoming multicast packet's destination matches the
             specified groupaddrs, the packet is not sent on the interfaces.
             Moreover, if there is no other interface than the specified
             interfaces, pim6dd(8) sends a prune message to the upstream
             neighbor.  Valid formats of groupaddrs are as follows.
             multicastaddr1-multicastaddr2
                     specifies a numerical range of a scope.  Multicast
                     addresses from multicastaddr1 to multicastaddr2 will be
                     filtered out.  Note that neither a white space nor a tab
                     character must not be inserted before nor after `-'.
             multicastaddr/prefixlen
                     specifies a group prefix of a scope.  Multicast addresses
                     which match the specified prefix will be filtered out.
                     If prefixlen is omitted, it means the exact match for
                     multicastaddr.
             interfaces are specified as a blank separated list of interfaces.
             Each interface is specified in the form of "name unit".


EXAMPLE

     # phyint gif0 disable
     # phyint ep0 preference 101
     phyint de0 disable
     filter ff15::4000/120 gif1 gif2
     filter ff18::1000-ff18::1050 gif3

HISTORY

     The pim6dd(8) command and the configuration file pim6dd.conf are based on
     pimdd, which is an IPv4 multicast routing daemon developed at the
     University of Oregon.  pimdd has been derived from PIM sparse-mode pimd
     developed at University of Southern California.  Part of these two
     programs above has also been derived from mrouted.  mrouted is COPYRIGHT
     1989 by The Board of Trustees of Leland Stanford Junior University.
