The IESG has received a request from the Multiprotocol Label Switching WG (mpls) to consider the following document: - 'mLDP In-Band Signaling with Wildcards' <draft-ietf-mpls-mldp-in-band-wildcard-encoding-02.txt> as Proposed Standard The IESG plans to make a decision in the next few weeks, and solicits final comments on this action. Please send substantive comments to the ietf@ietf.org mailing lists by 2014-10-27. Exceptionally, comments may be sent to iesg@ietf.org instead. In either case, please retain the beginning of the Subject line to allow automated sorting. 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. This document updates RFCs 6826 and 7246. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-mpls-mldp-in-band-wildcard-encoding/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-mpls-mldp-in-band-wildcard-encoding/ballot/ No IPR declarations have been submitted directly on this I-D.
