The IESG has received a request from the Multiprotocol Label Switching WG (mpls) to consider the following document: - 'LDP Extensions for Hub & Spoke Multipoint Label Switched Path' <draft-ietf-mpls-mldp-hsmp-04.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 2013-12-10. 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 This draft introduces a hub & spoke multipoint (HSMP) Label Switched Path (LSP), which allows traffic both from root to leaf through point-to-multipoint (P2MP) LSP and also leaf to root along the reverse path. That means traffic entering the HSMP LSP from application/customer at the root node travels downstream to each leaf node, exactly as if it is travelling downstream along a P2MP LSP to each leaf node. Upstream traffic entering the HSMP LSP at any leaf node travels upstream along the tree to the root, as if it is unicast to the root. The communication among the leaf nodes are not allowed. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-mpls-mldp-hsmp/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-mpls-mldp-hsmp/ballot/ The following IPR Declarations may be related to this I-D: http://datatracker.ietf.org/ipr/1777/ http://datatracker.ietf.org/ipr/2191/
