Internet Engineering Task Force (IETF) A. Lindem Request for Comments: 7503 Cisco Systems Updates: 5340 J. Arkko Category: Standards Track Ericsson ISSN: 2070-1721 April 2015 OSPFv3 Autoconfiguration Abstract OSPFv3 is a candidate for deployments in environments where autoconfiguration is a requirement. One such environment is the IPv6 home network where users expect to simply plug in a router and have it automatically use OSPFv3 for intra-domain routing. This document describes the necessary mechanisms for OSPFv3 to be self-configuring. This document updates RFC 5340 by relaxing the HelloInterval/ RouterDeadInterval checking during OSPFv3 adjacency formation and adding hysteresis to the update of self-originated Link State Advertisements (LSAs). 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.

Introduction OSPFv3 [OSPFV3] is a candidate for deployments in environments where autoconfiguration is a requirement. This document describes extensions to OSPFv3 to enable it to operate in these environments. In this mode of operation, the protocol is largely unchanged from the base OSPFv3 protocol specification [OSPFV3]. Since the goals of autoconfiguration and security can be conflicting, operators and network administrators should carefully consider their security requirements before deploying the solution described in this document. Refer to Section 8 for more information. The following aspects of OSPFv3 autoconfiguration are described inShow full document text
