RFC 7552: Updates to LDP for IPv6
IETF (Standards Track)
The Label Distribution Protocol (LDP) specification defines procedures to exchange label bindings over either IPv4 or IPv6 networks, or both. This document corrects and clarifies the LDP behavior when an IPv6 network is used (with or without IPv4). This document updates RFCs 5036 and 6720.

Supporting Authentication Trailer for OSPFv3
IETF RFC 7166
Currently, OSPF for IPv6 (OSPFv3) uses IPsec as the only mechanism for authenticating protocol packets. This behavior is different from authentication mechanisms present in other routing protocols (OSPFv2, Intermediate System to Intermediate System (IS-IS), RIP, and Routing Information Protocol Next Generation (RIPng)). In some environments, it has been found that IPsec is difficult to configure and maintain and thus cannot be used. This document defines an alternative mechanism to…
Currently, OSPF for IPv6 (OSPFv3) uses IPsec as the only mechanism for authenticating protocol packets. This behavior is different from authentication mechanisms present in other routing protocols (OSPFv2, Intermediate System to Intermediate System (IS-IS), RIP, and Routing Information Protocol Next Generation (RIPng)). In some environments, it has been found that IPsec is difficult to configure and maintain and thus cannot be used. This document defines an alternative mechanism to authenticate OSPFv3 protocol packets so that OSPFv3 does not depend only upon IPsec for authentication.
The OSPFv3 Authentication Trailer was originally defined in RFC 6506. This document obsoletes RFC 6506 by providing a revised definition, including clarifications and refinements of the procedures.Other authorsSee publication -
RBridges: Operations, Administration, and Maintenance (OAM) Support
IETF
Routing Bridges (RBridges) implement the TRansparent Interconnection of Lots of Links (TRILL) protocol which provide a transparent least-cost frame routing in multi-hop networks with arbitrary topologies, while also inherently providing loop mitigation. As RBridges are deployed in real-world situations, operators will need tools for debugging problems that arise. This document specifies a set of RBridge features for operations, administration, and maintenance (OAM) purposes in RBridge…

As RBridges are deployed in real-world situations, operators will need tools for debugging problems that arise. This document specifies a set of RBridge features for operations, administration, and maintenance (OAM) purposes in RBridge campuses. The features specified in this document include tools for traceroute, ping, and error reporting.

BFD Generic Cryptographic Authentication
IETF
This document proposes an extension to Bidirectional Forwarding Detection (BFD) to allow the use of any cryptographic authentication algorithm in addition to the already-documented authentication schemes described in the base specification. This document adds the basic infrastructure thats required for supporting algorithm and key agility for BFD.

Summary of Cryptographic Authentication Algorithm Implementation Requirements for Routing Protocols
IETF
The routing protocols OSPFv2, IS-IS and RIP currently define cleartext and MD5 methods for authenticating protocol packets. Recently, effort has been made to add support for the SHA Secure Hash Algorithm) family of hash functions for the purpose of authenticating routing protocol packets for RIP, IS-IS, and OSPF.
To encourage interoperability between disparate implementations, it is imperative that we specify the expected minimal set of algorithms, thereby ensuring that there is at least…The routing protocols OSPFv2, IS-IS and RIP currently define cleartext and MD5 methods for authenticating protocol packets. Recently, effort has been made to add support for the SHA Secure Hash Algorithm) family of hash functions for the purpose of authenticating routing protocol packets for RIP, IS-IS, and OSPF.
To encourage interoperability between disparate implementations, it is imperative that we specify the expected minimal set of algorithms, thereby ensuring that there is at least one algorithm that all implementations will have in common.
Similarly, RIP for IPv6 (RIPng) and OSPFv3 support IPsec algorithms for authenticating their protocol packets.
This RFC examines the current set of available algorithms, with interoperability and effective cryptographic authentication protection being the principal considerations. Cryptographic authentication of these routing protocols requires the availability of the same algorithms in disparate implementations. It is desirable that newly specified algorithms should be implemented and available in routing protocol implementations because they may be promoted to requirements at some future time.Other authorsSee publication -
Cryptographic Algorithm Implementation Requirements for Encapsulating Security Payload (ESP) and Authentication Header (AH)
IETF
See publicationThe IPsec series of protocols makes use of various cryptographic algorithms in order to provide security services. The Encapsulating Security Payload (ESP) and the Authentication Header (AH) provide two mechanisms for protecting data being sent over an IPsec Security Association (SA). To ensure interoperability between disparate implementations, it is necessary to specify a set of mandatory-to-implement algorithms to ensure that there is at least one algorithm that all implementations will…

Considerations When Using Basic OSPF Convergence Benchmarks
RFC 4063
This document discusses the applicability of various tests for measuring single router control plane convergence, specifically in regard to the Open Shortest First (OSPF) protocol. There are two general sections in this document, the first discusses advantages and limitations of specific OSPF convergence tests, and the second discusses more general pitfalls to be considered when routing protocol convergence is tested.

OSPF Benchmarking Terminology and Concepts
RFC 4062
See publicationThis document explains the terminology and concepts used in OSPF benchmarking. Although some of these terms may be defined elsewhere (and we will refer the reader to those definitions in some cases) we include discussions concerning these terms, as they relate specifically to the tasks involved in benchmarking the OSPF protocol.
