RFC 2590 IPv6 over Frame Relay Networks May 1999
1. 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.
