2. Abstract
This document describes how intra-LIS IP multicast can be efficiently
supported among routers over ATM without using the Multicast Address
Resolution Server (MARS). The method described here is specific to
Sparse Mode PIM [PIM-SM], and relies on the explicit join mechanism
inherent in PIM-SM to notify routers when they should create group
specific point-to-multipoint VCs.
3. Overall model
This document focuses on forwarding of multicast traffic among PIM-SM
routers connected to an ATM network. Routers on an ATM network are
partitioned into Logical IP Subnets, or LISs. This document deals
with handling multicast within a single LIS. Handling inter-LIS
multicast traffic, including handling shortcuts, is outside the scope
of this document. In addition, this document does not address
forwarding of multicast traffic to or from hosts connected to an ATM
network.
