<abstract>
<t>
   A mechanism to support the multicast needs of layer 3 protocols in
   general, and IP in particular, over UNI 3.0/3.1 based ATM networks
   has been described in RFC 2022.  Two basic approaches exist for the
   intra-subnet (intra-cluster) multicasting of IP packets.  One makes
   use of a mesh of point to multipoint VCs (the &apos;VC Mesh&apos; approach),
   while the other uses a shared point to multipoint tree rooted on a
   Multicast Server (MCS). This memo provides details on the design and
   implementation of an MCS, building on the core mechanisms defined in
   RFC 2022.  It also provides a mechanism for using multiple MCSs per
   group for providing fault tolerance.  This approach can be used with
   RFC 2022 based MARS server and clients, without needing any change in
   their functionality.
