1. Introduction
This memo defines a portion of the Management Information Base (MIB)
for use with network management protocols in the Internet community.
In particular, it describes managed objects for modeling a
Multiprotocol Label Switching (MPLS) [RFC3031] based traffic
engineering. This MIB module should be used in conjunction with the
companion document [RFC3813] for MPLS based traffic engineering
configuration and management.
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 BCP 14, RFC 2119,
reference [RFC2119].
2. Terminology
This document uses terminology from the MPLS architecture document
[RFC3031] and MPLS Label Switch Router MIB [RFC3813]. Some
frequently used terms are described next.
An explicitly routed LSP (ERLSP) is referred to as an MPLS tunnel.
It consists of in-segment(s) and/or out-segment(s) at the
egress/ingress LSRs, each segment being associated with one MPLS
interface. These are also referred to as tunnel segments.
Additionally, at an intermediate LSR, we model a connection as
consisting of one or more in-segments and/or one or more out-
segments. The binding or interconnection between in-segments and
