mpls-label

description:
type for MPLS label value encoding

type: union

type: uint32

• range: 16..1048575

type: enumeration

• IPV4_EXPLICIT_NULL
  valid at the bottom of the label stack, indicates that stack must be popped and packet forwarded based on IPv4 header
• ROUTER_ALERT
  allowed anywhere in the label stack except the bottom, local router delivers packet to the local CPU when this label is at the top of the stack
• IPV6_EXPLICIT_NULL
  valid at the bottom of the label stack, indicates that stack must be popped and packet forwarded based on IPv6 header
• IMPLICIT_NULL
  assigned by local LSR but not carried in packets
• ENTROPY_LABEL_INDICATOR
  Entropy label indicator, to allow an LSR to distinguish between entropy label and applicaiton labels RFC 6790
• NO_LABEL
  This value is utilised to indicate that the packet that is forwarded by the local system does not have an MPLS header applied to it. Typically, this is used at the egress of an LSP

tunnel-type

description:
defines the tunnel type for the LSP

type: enumeration

• P2P
  point-to-point label-switched-path
• P2MP
  point-to-multipoint label-switched-path
• MP2MP
  multipoint-to-multipoint label-switched-path

bandwidth-kbps

description:
Bandwidth values expressed in kilobits per second

type: uint64

units: Kbps

bandwidth-mbps

description:
Bandwidth values expressed in megabits per second

type: uint64

units: Mbps

bandwidth-gbps

description:
Bandwidth values expressed in gigabits per second

type: uint64

units: Gbps

mpls-tc

description:
Values of the MPLS Traffic Class (formerly known as Experimental, EXP) bits

type: uint8

• range: 0..7

Identities

base: PATH_COMPUTATION_METHOD

description:
base identity for supported path computation mechanisms

LOCALLY_COMPUTED

description:
indicates a constrained-path LSP in which the path is computed by the local LER

base identity: PATH_COMPUTATION_METHOD

EXTERNALLY_QUERIED

description:
Constrained-path LSP in which the path is obtained by querying an external source, such as a PCE server. In the case that an LSP is defined to be externally queried, it may also have associated explicit definitions (which are provided to the external source to aid computation); and the path that is returned by the external source is not required to provide a wholly resolved path back to the originating system - that is to say, some local computation may also be required

base identity: PATH_COMPUTATION_METHOD

EXPLICITLY_DEFINED

description:
constrained-path LSP in which the path is explicitly specified as a collection of strict or/and loose hops

base identity: PATH_COMPUTATION_METHOD

openconfig-mpls

openconfig-version: 3.6.0

Description

This module provides data definitions for configuration of Multiprotocol Label Switching (MPLS) and associated protocols for signaling and traffic engineering.

RFC 3031: Multiprotocol Label Switching Architecture

The MPLS / TE data model consists of several modules and submodules as shown below. The top-level MPLS module describes the overall framework. Three types of LSPs are supported:

i) traffic-engineered (or constrained-path)

ii) IGP-congruent (LSPs that follow the IGP path)

iii) static LSPs which are not signaled

The structure of each of these LSP configurations is defined in corresponding submodules. Companion modules define the relevant configuration and operational data specific to key signaling protocols used in operational practice.

enumerated type for specifying loose or strict paths

type: enumeration

description:
type to indicate the CSPF selection policy when multiple equal cost paths are available

type: enumeration

• RANDOM

• MOST_FILL
  CSPF calculation selects the path with the least available bandwidth

default: RANDOM
