Abstract:
Sometimes an IP multicast distribution tree (MDT) traverses both
MPLS-enabled and non-MPLS-enabled regions of a network. Typically
the MDT begins and ends in non-MPLS regions, but travels through an
MPLS region. In such cases, it can be useful to begin building the
MDT as a pure IP MDT, then convert it to an MPLS Multipoint LSP
(Label Switched Path) when it enters an MPLS-enabled region, and then
convert it back to a pure IP MDT when it enters a non-MPLS-enabled
region. Other documents specify the procedures for building such a
hybrid MDT, using Protocol Independent Multicast (PIM) in the non-
MPLS region of the network, and using Multipoint Extensions to Label
Distribution Protocol (mLDP) in the MPLS region. This document
extends those procedures to handle the case where the link connecting
the two regions is a "Virtual Routing and Forwarding Table" (VRF)
link, as defined in the "BGP IP/MPLS VPN" specifications. However,
this document is primarily aimed at particular use cases where VRFs
are used to support multicast applications other than Multicast VPN.
