Abstract:
There are scenarios in which an IP multicast tree traverses an MPLS
domain. In these scenarios, it can be desirable to convert the IP
multicast tree "seamlessly" to an MPLS multipoint label switched path
(MP-LSP) when it enters the MPLS domain, and then to convert it back
to an IP multicast tree when it exits the MPLS domain. Previous
documents specify procedures that allow certain kinds of IP multicast
trees (either "Source-Specific Multicast" trees or "Bidirectional
Multicast" trees) to be attached to an MPLS Multipoint Label Switched
Path (MP-LSP). However, the previous documents do not specify
procedures for attaching IP "Any Source Multicast" trees to MP-LSPs,
nor do they specify procedures for aggregating multiple IP multicast
trees onto a single MP-LSP. This document specifies the procedures
to support these functions. It does so by defining "wildcard"
encodings that make it possible to specify, when setting up an MP-
LSP, that a set of IP multicast trees, or a shared IP multicast tree,
should be attached to that MP-LSP. Support for non-bidirectional IP
"Any Source Multicast" trees is subject to certain applicability
restrictions that are discussed in this document.
