Consider an IP multicast tree, constructed by Protocol Independent
Multicast (PIM), needs to pass through an MPLS domain in which
Multipoint LDP (mLDP) Point-to-Multipoint and/or Multipoint-to-
Multipoint Labels Switched Paths (LSPs) can be created. The part of
the IP multicast tree that traverses the MPLS domain can be
instantiated as a multipoint LSP. When a PIM Join message is
received at the border of the MPLS domain, information from that
message is encoded into mLDP messages. When the mLDP messages reach
the border of the next IP domain, the encoded information is used to
generate PIM messages that can be sent through the IP domain. The
result is an IP multicast tree consisting of a set of IP multicast
sub-trees that are spliced together with a multipoint LSP.
