Abstract
This memo defines two MIB modules and corresponding MIB Object
Definitions that describe how label-switching-controlled Frame-Relay
and Asynchronous Transfer Mode (ATM) interfaces can be managed given
the interface stacking as defined in the MPLS-LSR-STD-MIB and
MPLS-TE-STD-MIB.

RFC 4368 MPLS LC ATM and FR MIBs January 2006
1. Introduction
This memo defines how label-switching-controlled Frame-Relay
[RFC3034] and ATM [RFC3035] interfaces can be realized given the
interface stacking as defined in the MPLS-LSR-STD [RFC3813] and
MPLS-TE-STD [RFC3812] MIBs. This document also contains a MIB module
that sparsely extends the MPLS-LSR-STD MIB's mplsInterfaceConfTable
in such a way as to identify which MPLS-type interfaces have LC-ATM
or LC-FR capabilities. Comments should be made directly to the MPLS
mailing list at mpls@uu.net.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in RFC 2119, reference
[RFC2119].
2. Terminology
This document uses terminology from the document describing the MPLS
architecture [RFC3031], as well as from RFC 3035 and RFC 3034.
Specifically, the following terms will be used in this document.
C-FR RFC 3034 defines a label-switching-controlled Frame Relay
(LC-FR) interface. Packets traversing such an interface carry
labels in the DLCI field
C-ATM RFC 3035 defines a label-switching-controlled ATM (LC-ATM)
interface as an ATM interface controlled by the label switching
control component. When a packet traversing such an interface
is received, it is treated as a labeled packet. The packet's
top label is inferred from either the contents of the Virtual
Channel Identifier (VCI) field or the combined contents of the
Virtual Path Identifier (VPI) and VCI fields. Any two LDP
peers that are connected via an LC-ATM interface will use LDP
negotiations to determine which of these cases is applicable to
that interface. Static configuration of labels is also
possible.
When LDP is used to distribute labels for use on label-controlled
interfaces, label configuration information may be available in the
MPLS-LDP-ATM-STD-MIB [RFC3815] when LC-ATM interfaces are used, or
the MPLS-LDP-FRAME-RELAY-STD-MIB [RFC3815] when LC-FR interfaces are
used.
