NAME
     mrouted - IP multicast routing daemon

SYNOPSIS
     mrouted [-c config_file] [-d [debug_level]] [-p]

DESCRIPTION
     Mrouted is an implementation of the Distance-Vector Multicast Routing
     Protocol (DVMRP), an earlier version of which is specified in RFC-1075.
     It maintains topological knowledge via a distance-vector routing protocol
     (like RIP, described in RFC-1058), upon which it implements a multicast
     datagram forwarding algorithm called Reverse Path Multicasting.

     Mrouted forwards a multicast datagram along a shortest (reverse) path
     tree rooted at the subnet on which the datagram originates.  The multi-
     cast delivery tree may be thought of as a broadcast delivery tree that
     has been pruned back so that it does not extend beyond those subnetworks
     that have members of the destination group.  Hence, datagrams are not
     forwarded along those branches which have no listeners of the multicast
     group.  The IP time-to-live of a multicast datagram can be used to limit
     the range of multicast datagrams.
