        RFC 1584:

        Title:      Multicast Extensions to OSPF
        Author:     J. Moy

This memo documents enhancements to the OSPF protocol enabling the
routing of IP multicast datagrams. In this proposal, an IP multicast
packet is routed based both on the packet's source and its multicast
destination (commonly referred to as source/destination routing).  As
it is routed, the multicast packet follows a shortest path to each
multicast destination. During packet forwarding, any commonality of
paths is exploited; when multiple hosts belong to a single multicast
group, a multicast packet will be replicated only when the paths to
the separate hosts diverge.  This RFC is the product of the Multicast
Extensions to OSPF Working Group of the IETF.

This is now a Proposed Standard Protocol.

This document specifies an Internet standards track protocol for the
Internet community, and requests discussion and suggestions for
improvements.  Please refer to the current edition of the "Internet
Official Protocol Standards" (STD 1) for the standardization state and
status of this protocol.  Distribution of this memo is unlimited.
