Internet Engineering Task Force (IETF) D. Li Request for Comments: 6898 Huawei Updates: 4204, 4207, 4209, 5818 D. Ceccarelli Category: Standards Track Ericsson ISSN: 2070-1721 L. Berger LabN March 2013 Link Management Protocol Behavior Negotiation and Configuration Modifications Abstract The Link Management Protocol (LMP) is used to coordinate the properties, use, and faults of data links in networks controlled by Generalized Multiprotocol Label Switching (GMPLS). This document defines an extension to LMP to negotiate capabilities and indicate support for LMP extensions. The defined extension is compatible with non-supporting implementations. This document updates RFC 4204, RFC 4207, RFC 4209, and RFC 5818. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 5741.

Standards Track [Page 2] RFC 6898 LMP Behavior Negotiation March 2013 1. Introduction The Link Management Protocol (LMP) [RFC4204] has been successfully deployed in networks controlled by Generalized Multiprotocol Label Switching (GMPLS). New LMP behaviors and protocol extensions have been introduced in a number of IETF documents, as set out later in this section. It is likely that future extensions will be made to support additional functions. In a network, if one LMP-capable node supports a new behavior or protocol extension but its adjacent node does not, it is beneficial to have a protocol mechanism to discover the capabilities of peer nodes so that the right protocol extensions can be selected and the correct features can be enabled. There are no such procedures defined in the base LMP specification [RFC4204]. [RFC4209] defined a specific mechanism to identify support for the functions specified in that document. This document defines an LMP extension to support the identification of supported LMP functions in a generic fashion, as well as how a node supporting these extensions would communicate withShow full document text
