The IESG has approved the following document: - 'mLDP In-Band Signaling with Wildcards' (draft-ietf-mpls-mldp-in-band-wildcard-encoding-03.txt) as Proposed Standard This document is the product of the Multiprotocol Label Switching Working Group. The IESG contact persons are Adrian Farrel and Alia Atlas. A URL of this Internet Draft is: http://datatracker.ietf.org/doc/draft-ietf-mpls-mldp-in-band-wildcard-encoding/ Technical Summary There are scenarios in which an IP multicast tree traverses an MPLS domain. It may be desirable to convert the IP multicast tree "seamlessly" to an MPLS multipoint label switched path (MP-LSP) when the multicast tree enters into the MPLS domain. Similarly, the MP-LSP is converted back to an IP multicast tree when the MPLS domain is exited. Previous documents specify procedures for certain kinds of IP multicast trees to be attached to an MPLS Multipoint Label Switched Path (MP-LSP). These 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. This document updates RFCs 6826 and 7246. Working Group Summary This document and another document (draft-ietf-mpls-pim-sm-over-mldp) at the time they were adopted as working group document had a certain overlap. draft-ietf-mpls-pim-sm-over-mldp is just being prepared for wglc The overlap was resolved by clearly scoping the two documents, and after that both documents has progressed smoothly. Document Quality We know of existing implementations of this protocol. We also know of vendors that plan to implement and operators that have deployed the protocol. The level of review for this document is good, it has been reviewed by the shepherd and wg chairs a number of times, it has been through MPLS-RT review, wg adoption poll, wglc and RTG Area Quality Assurance review. Personnel Loa Andersson is the Document Shepherd. Adrian Farrel is the Responsible AD. RFC Editor Note Section 2 s/This draft also/This document also/
