The IESG has received a request from the Multiprotocol Label Switching WG (mpls) to consider the following document: - 'Application-aware Targeted LDP' <draft-ietf-mpls-app-aware-tldp-08.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 2017-06-09. 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 Recent targeted LDP (tLDP) applications such as remote loop-free alternate (LFA) and BGP auto discovered pseudowire may automatically establish a tLDP session to any LSR in a network. The initiating LSR has information about the targeted applications to administratively control initiation of the session. However, the responding LSR has no such information to control acceptance of this session. This document defines a mechanism to advertise and negotiate Targeted Applications Capability (TAC) during LDP session initialization. As the responding LSR becomes aware of targeted applications, it may establish a limited number of tLDP sessions for certain applications. In addition, each targeted application is mapped to LDP Forwarding Equivalence Class (FEC) Elements to advertise only necessary LDP FEC- label bindings over the session. This document updates RFC 7473 for enabling advertisement of LDP FEC-label bindings over the session.
