A new Request for Comments is now available in online RFC libraries. RFC 8679 Title: MPLS Egress Protection Framework Author: Y. Shen, M. Jeganathan, B. Decraene, H. Gredler, C. Michel, H. Chen Status: Standards Track Stream: IETF Date: December 2019 Mailbox: yshen@juniper.net, minto@juniper.net, bruno.decraene@orange.com, hannes@rtbrick.com, c.michel@telekom.de, huaimo.chen@futurewei.com Pages: 25 Updates/Obsoletes/SeeAlso: None I-D Tag: draft-ietf-mpls-egress-protection-framework-07.txt URL: https://www.rfc-editor.org/info/rfc8679 DOI: 10.17487/RFC8679 This document specifies a fast reroute framework for protecting IP/MPLS services and MPLS transport tunnels against egress node and egress link failures. For each type of egress failure, it defines the roles of Point of Local Repair (PLR), protector, and backup egress router and the procedures of establishing a bypass tunnel from a PLR to a protector. It describes the behaviors of these routers in handling an egress failure, including local repair on the PLR and context-based forwarding on the protector. The framework can be used to develop egress protection mechanisms to reduce traffic loss before global repair reacts to an egress failure and control-plane protocols converge on the topology changes due to the egress failure. This document is a product of the Multiprotocol Label Switching Working Group of the IETF. This is now a Proposed Standard. STANDARDS TRACK: This document specifies an Internet Standards Track protocol for the Internet community, and requests discussion and suggestions for improvements. Please refer to the current edition of the Official Internet Protocol Standards (https://www.rfc-editor.org/standards) for the standardization state and status of this protocol.
