A YANG Data Model for MPLS Static LSPs
draft-ietf-mpls-static-yang-10
Abstract
This document contains the specification for the MPLS Static Label
Switched Paths (LSPs) YANG model. The model allows for the
provisioning of static LSP(s) on Label Edge Router(s) LER(s) and
Label Switched Router(s) LSR(s) devices along a LSP path without the
dependency on any signaling protocol. The MPLS Static LSP model
augments the MPLS base YANG model with specific data to configure and
manage MPLS Static LSP(s).

1. Introduction
This document describes a YANG [RFC7950] data model for configuring
and managing the Multiprotocol Label Switching (MPLS) [RFC3031]
Static LSPs. The model allows the configuration of LER and LSR
devices with the necessary MPLS cross-connects or bindings to realize
an end-to-end LSP service.
A static LSP is established by manually specifying incoming and
outgoing MPLS label(s) and necessary forwarding information on each
of the traversed LER and LSR devices (ingress, transit, or egress
nodes) of the forwarding path.
For example, on an ingress LER device, the model is used to associate
a specific Forwarding Equivalence Class (FEC) of packets- e.g.
matching a specific IP prefix in a Virtual Routing or Forwarding
(VRF) instance- to an MPLS outgoing label imposition, next-hop(s) and
respective outgoing interface(s) to forward the packet. On an LSR
device, the model is used to create a binding that swaps the incoming
label with an outgoing label and forwards the packet on one or
Saad, et al. Expires March 15, 2020 [Page 2]
Internet-Draft MPLS Static LSPs YANG Data Model September 2019
multiple egress path(s). On an egress LER, it is used to create a
binding that decapsulates the incoming MPLS label and performs
forwarding based on the inner MPLS label (if present) or IP
forwarding in the packet.
The MPLS Static LSP YANG model is broken into two modules "ietf-mpls-
static" and "ietf-mpls-static-extended". The "ietf-mpls-static"
module covers basic features for the configuration and management of
unidirectional Static LSP(s), while "ietf-mpls-static-extended"
covers extended features like the configuration and management of
bidirectional Static LSP(s) and LSP admission control.
The module "ietf-mpls-static" augments the MPLS Base YANG model
defined in module "ietf-mpls" in [I-D.ietf-mpls-base-yang].
1.1. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "NOT RECOMMENDED", "MAY", and
"OPTIONAL" in this document are to be interpreted as described in BCP
14 [RFC2119] [RFC8174] when, and only when, they appear in all
capitals, as shown here.
The terminology for describing YANG data models is found in
[RFC7950].

2.1. Model Organization
The base MPLS Static LSP model covers the core features with the
minimal set of configuration parameters needed to manage and operate
MPLS Static LSPs.
Additional MPLS Static LSP parameters as well as optional feature(s)
are grouped in a separate MPLS Static LSP extended model. The
relationship between the MPLS base and other MPLS modules are shown
in Figure 1.

2.3. Model Overview
This document defines two YANG modules for MPLS Static LSP(s)
configuration and management: ietf-mpls-static.yang and ietf-mpls-
static-extended.yang.
The ietf-mpls-static module contains the following high-level types
and groupings:
static-lsp-ref:
A YANG reference type for a static LSP that can be used by data
models to reference a configured static LSP.
in-segment:
A YANG grouping that describes parameters of an incoming class of
FEC associated with a specific LSP as described in the MPLS
architecture document [RFC3031]. The model allows the following
types of traffic to be mapped onto the static LSP on an ingress
LER:
o Unlabeled traffic destined to a specific prefix
o Labeled traffic arriving with a specific label
out-segment:
A YANG grouping that describes parameters for the forwarding
path(s) and their associated attributes for an LSP. The model
allows for the following cases:
o single forwarding path or NHLFE
o multiple forwarding path(s) or NHLFE(s), each of which can
serve a primary, backup or both role(s).
The ietf-mpls-static-extended module contains the following high-
level types and groupings:
bidir-static-lsp:
A YANG grouping that describes list of static bidirectional LSPs
The ietf-mpls-static-extended augments the ietf-mpls-static model
with additional parameters to configure and manage:
o Bidirectional Static LSP(s)
o Defining Static LSP bandwidth allocation
Saad, et al. Expires March 15, 2020 [Page 6]
Internet-Draft MPLS Static LSPs YANG Data Model September 2019
o Defining Static LSP preemption priorities
2.4. Model YANG Module(s)
Configuring LSPs through an LSR/LER involves the following steps:
o Enabling MPLS on MPLS capable interfaces.
o Configuring in-segments and out-segments on LER(s) and LSR(s)
traversed by the LSP.
o Setting up the cross-connect per LSP to associate segments and/or
to indicate connection origination and termination.
o Optionally specifying label stack actions.
o Optionally specifying segment traffic parameters.
The objects covered by this model are derived from the Incoming Label
Map (ILM) and Next Hop Label Forwarding Entry (NHLFE) as specified in
the MPLS architecture document [RFC3031].
The ietf-mpls-static module imports the followinig modules:
o ietf-inet-types defined in [RFC6991]
o ietf-routing defined in [RFC8349]
o ietf-routing-types defined in [RFC8294]
o ietf-interfaces defined in [RFC8343]
o ietf-mpls defined in [I-D.ietf-mpls-base-yang]
o ietf-te defined in [I-D.ietf-teas-yang-te]

4. Security Considerations
The YANG modules specified in this document define schemas for data
that is designed to be accessed via network management protocols such
as NETCONF [RFC6241] or RESTCONF [RFC8040]. The lowest NETCONF layer
is the secure transport layer, and the mandatory-to-implement secure
transport is Secure Shell (SSH) [RFC6242]. The lowest RESTCONF layer
is HTTPS, and the mandatory-to-implement secure transport is TLS
{!RFC8446}}.
The NETCONF access control model [RFC8341] provides the means to
restrict access for particular NETCONF or RESTCONF users to a
preconfigured subset of all available NETCONF or RESTCONF protocol
operations and content.
All nodes defined in this YANG module that are writable/creatable/
deletable (i.e., config true, which is the default) may be considered
sensitive or vulnerable in some network environments. Write
operations (e.g., edit-config) to these data nodes without proper
protection can have a negative effect on network operations. These
are the subtrees and data nodes and their sensitivity/vulnerability:
o /ietf-routing:routing/ietf-mpls:mpls:/ietf-mpls:static-lsps: This
entire subtree is related to security.
An administrator needs to restrict write access to all configurable
objects within this data model.
