Introduction This document specifies the frame format for transmission of IPv6 packets over Frame Relay networks, the method of forming IPv6 link- local addresses on Frame Relay links, and the mapping of the IPv6 addresses to Frame Relay addresses. It also specifies the content of the Source/Target link-layer address option used in Neighbor Discovery [ND] and Inverse Neighbor Discovery [IND] messages when those messages are transmitted over a Frame Relay link. It is part of a set of specifications that define such IPv6 mechanisms for Non Broadcast Multi Access (NBMA) media [IPv6-NBMA], [IPv6-ATM], and a larger set that defines such mechanisms for specific link layers [IPv6-ETH], [IPv6-FDDI], [IPv6-PPP], [IPv6-ATM], etc... The information in this document applies to Frame Relay devices which serve as end stations (DTEs) on a public or private Frame Relay network (for example, provided by a common carrier or PTT.) Frame Relay end stations can be IPv6 hosts or routers. In this document they are referred to as nodes. In a Frame Relay network, a number of virtual circuits form the connections between the attached stations (nodes). The resulting set of interconnected devices forms a private Frame Relay group which may be either fully interconnected with a complete "mesh" of virtual circuits, or only partially interconnected. In either case, each virtual circuit is uniquely identified at each Frame Relay interface (card) by a Data Link Connection Identifier (DLCI). In most circumstances, DLCIs have strictly local significance at each Frame Relay interface. A Frame Relay virtual circuit acts like a virtual-link (also referred to as logical-link), with its own link parameters, distinct from the parameters of other virtual circuits established on the same wire or fiber. Such parameters are the input/output maximum frame size, incoming/outgoing requested/agreed throughput, incoming/outgoing acceptable throughput, incoming/outgoing burst size, incoming/outgoing frame rate. By default a DLCI is 10 bits in length. Frame Relay specifications define also 16, 17, or 23 bit DLCIs. The former is not used, while the latter two are suggested for use with SVCs. Frame Relay virtual circuits can be created administratively as Permanent Virtual Circuits -- PVCs -- or dynamically as Switched Virtual Circuits -- SVCs. The mechanisms defined in this document are intended to apply to both permanent and switched Frame Relay virtual circuits, whether they are point to point or point to multi- point. Conta, et al.
