The IESG has received a request from the Multiprotocol Label Switching WG (mpls) to consider the following document: - 'Using Multipoint LDP when the Backbone has no Route to the Root' <draft-ietf-mpls-mldp-recurs-fec-03.txt> as a 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 2011-07-11. 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 The control protocol used for constructing Point-to-Multipoint and Multipoint-to-Multipoint Label Switched Paths ("MP LSPs") contains a field that identifies the address of a "root node". Intermediate nodes are expected to be able to look up that address in their routing tables. However, if the route to the root node is a BGP route, and the intermediate nodes are part of a BGP-free core, this is not possible. This document specifies procedures which enable a MP LSP to be constructed through a BGP-free core. In these procedures, the root node address is temporarily replaced by an address that is known to the intermediate nodes and is on the path to the true root node. The file can be obtained via http://datatracker.ietf.org/doc/draft-ietf-mpls-mldp-recurs-fec/ IESG discussion can be tracked via http://datatracker.ietf.org/doc/draft-ietf-mpls-mldp-recurs-fec/ No IPR declarations have been submitted directly on this I-D.
