[RFC9552] describes a mechanism by which Link-State (LS) and Traffic Engineering (TE) topology information can be collected from Interior Gateway Protocols (IGPs) and distributed to external components using the Border Gateway Protocol (BGP). When combined with the Shortest Path First (SPF) algorithm, this mechanism allows BGP to compute routes directly from the distributed topology. [RFC9815] describes BGP Link-State Shortest Path First (BGP-LS-SPF) routing, a mode that enables BGP to serve as both the underlay and overlay protocol in Massively Scaled Data Centers (MSDCs). This document defines a YANG 1.1 [RFC7950] data model for configuring BGP-LS, BGP-LS-VPN, and BGP-LS-SPF on a router. It also defines a read-only model for the Link-State Database (LSDB), which stores the Node, Link, Prefix, and SRv6 Segment Identifier (SID) Network Layer Reachability Information (NLRI) received via BGP-LS.¶
The data model is organized across five YANG modules. The
ietf-bgp-ls module augments the BGP configuration model
to add the three new address families: BGP-LS, BGP-LS-VPN, and
BGP-LS-SPF. The ietf-bgp-lsdb module provides the
read-only Link-State Database, together with submodules that define
the Node, Link, Prefix, and SRv6 SID NLRI types and their
associated attributes. The attribute definitions in those
submodules cover the IGP topology attributes from
[RFC9552], the Segment Routing extensions from
[RFC9085], the BGP Peering Segment extensions from
[RFC9086], the Flexible Algorithm extensions from
[RFC9351], and the SRv6 extensions from
[RFC9514].¶
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 tree diagram below shows an abridged view of the
ietf-bgp-ls module and the top-level containers of the
ietf-bgp-lsdb module. The bgp-ls-topology
container holds one or more instances, each identified by a VRF
name, protocol (IS-IS Level 1 or Level 2, OSPFv2, OSPFv3, or
BGP), and a 64-bit domain identifier. Within each instance,
separate containers hold the Node, Link, Prefix, and SRv6 SID
NLRIs indexed by their protocol-specific key fields. A complete
tree diagram is provided in Appendix A.
Annotations used in the diagram are defined in
[RFC8340].¶

The ietf-bgp-ls module augments the BGP model
[I-D.ietf-idr-bgp-model] to add support for
three new Address Family Indicator (AFI) / Subsequent Address
Family Indicator (SAFI) combinations: BGP-LS, BGP-LS-VPN, and
BGP-LS-SPF.¶
The BGP model is augmented both at a global level and at a
neighbor level to add support for the three new AFI/SAFI
combinations. In addition, there is support for per-address-family
statistics both at a global and at a neighbor level. The
clear-statistics feature defined in
[I-D.ietf-idr-bgp-model] is used in this model to
determine whether the ability to clear statistics is supported.¶
The module imports ietf-yang-types and
ietf-inet-types [RFC9911],
ietf-routing [RFC8349], and the BGP
module from [I-D.ietf-idr-bgp-model].¶

(EPE) defines a BGP Node NLRI type for advertising BGP peer node
descriptors [RFC9086]; a corresponding list will
be added in a future revision of this model.¶
links contains protocol-specific lists for IS-IS
links, OSPFv2 links, OSPFv3 links, and BGP Egress Peer
Engineering (EPE) links [RFC9086]. IS-IS and OSPF
links are keyed by the local and remote node identifiers together
with the local and remote IPv4 and IPv6 interface addresses; a
sentinel value of 0.0.0.0 (for IPv4) or :: (for IPv6) MUST be
used when an address is absent, for example on unnumbered or
single-stack links. BGP links carry additional key fields for the
local and remote AS numbers and BGP Router IDs. Each link entry
carries the IGP link attributes defined in
ietf-bgp-ls-topo-attr.¶
prefixes contains protocol-specific lists for IS-IS,
OSPFv2, and OSPFv3 prefixes. IS-IS prefix entries are keyed by
system-id, pseudo-node identifier, AS number, multi-topology-id,
and prefix value. OSPFv2 and OSPFv3 prefix entries are keyed by
the AS-scoped flag, area-id, router-id, designated-router
identifier, AS number, multi-topology-id, route-type, and prefix
value. Each prefix entry carries the prefix attributes defined in
ietf-bgp-ls-topo-attr.¶
srv6-sids contains protocol-specific lists for
OSPFv3, IS-IS, and BGP SRv6 SIDs. OSPFv3 SRv6 SID entries are
keyed by the AS-scoped flag, area-id, router-id,
designated-router identifier, AS number, SID value, and
multi-topology-id. IS-IS SRv6 SID entries are keyed by
system-id, pseudo-node identifier, AS number, SID value, and
multi-topology-id. BGP SRv6 SID entries are keyed by router-id,
AS number, SID value, and multi-topology-id. Each SRv6 SID
entry carries the SRv6 SID attributes defined in
ietf-bgp-ls-topo-attr.¶
unknowns provides a fallback container for NLRI types
not recognized by the model, stored as opaque hex-encoded NLRI
and attribute values.¶
The module includes the ietf-bgp-ls-topo-attr,
ietf-bgp-ls-topo-ospf, and
ietf-bgp-ls-topo-types submodules, and imports
ietf-yang-types and ietf-inet-types
[RFC9911], ietf-routing-types
[RFC8294], ietf-isis
[RFC9130], and ietf-ospf

<CODE ENDS>
The ietf-bgp-ls-topo-types submodule defines the
identity hierarchy and typedefs shared across the other
topology attribute submodules.¶
The base identity bgp-ls-topo-attr-type is the root
for approximately fifty derived identities, one per BGP-LS TLV
type. Examples include bgp-ls-topo-attr-node-name (TLV
1026), bgp-ls-topo-attr-sr-capabilities (TLV 1034),
bgp-ls-topo-attr-fad (TLV 1039),
bgp-ls-topo-attr-extended-admin-group (TLV 1173), and
bgp-ls-topo-attr-adjacency-sid (TLV 1099). These
identities serve as the key type in the type-dispatched attribute
lists defined in ietf-bgp-ls-topo-attr, enabling new TLV
types to be added as derived identities without modifying the
existing schema structure.¶
The base identity bgp-ls-topo-attr-fad-type
enumerates the sub-TLV types that appear within a Flexible
Algorithm Definition (FAD) [RFC9351], such as
include/exclude affinity constraints, SRLG exclusions, minimum
bandwidth, and maximum delay.¶
The sid-format typedef is an enumeration
distinguishing whether a SID value is an MPLS label (20-bit) or
an index into the SRGB (32-bit). It is referenced by the
adjacency-SID, prefix-SID, and BGP peer SID attribute
containers.¶
The protocol typedef enumerates the IGP protocols
from which BGP-LS NLRIs can originate: IS-IS Level 1, IS-IS Level
2, OSPFv2, OSPFv3, BGP, and Direct.¶

<CODE ENDS>
The ietf-bgp-ls-topo-attr submodule defines groupings
for the attributes associated with Node, Link, Prefix, and SRv6
SID NLRIs. Each grouping uses a type-dispatched list pattern: a
list keyed by an identityref of base type
bgp-ls-topo-attr-type, where each list entry carries a
set of containers guarded by
derived-from-or-self() when expressions. Only
the container whose identity matches the entry's key leaf is
active in any given entry. This approach provides an extensible
schema that accommodates new TLV types by adding derived
identities without modifying the list structure.¶
Node attributes
(bgp-ls-topo-node-attr): The node attribute list covers
the TLVs defined in [RFC9552] for router
identification (local IPv4/IPv6 Router-IDs, node name),
node properties (Multi-Topology IDs, node flag bits, IS-IS area
identifiers, opaque node attributes), Segment Routing capabilities
(SRGB ranges, SRLB ranges, SR algorithms, node Maximum SID Depth
(MSD) [RFC8814]), and Flexible Algorithm
Definitions (FADs). Each FAD entry is identified by an algorithm
number in the range 128-255 and carries its metric type,
calculation type, priority, and a nested type-dispatched list of
affinity and SRLG constraint attributes as defined in
[RFC9351].¶
Link attributes
(bgp-ls-topo-igp-link-attr): The link attribute list
covers the TE and SR TLVs defined in [RFC9552] and
[RFC9085]. Traffic engineering attributes include
maximum bandwidth, maximum reservable bandwidth, unreserved
bandwidth (eight priority levels), administrative group, extended
administrative group (TLV 1173), TE metric, link protection type,
and Shared Risk Link Group (SRLG) values. Performance attributes
include unidirectional link delay (average, minimum, and maximum),
delay variation, link loss, residual bandwidth, available
bandwidth, and utilized bandwidth. SR attributes include
adjacency-SIDs (TLV 1099) and LAN adjacency-SIDs (TLV 1100)
[RFC9085], each carrying label or index values,
flags, and weights; link MSD; SRv6 End.X SIDs; and SRv6 LAN
End.X SIDs [RFC9514]. Application-Specific Link
Attributes (ASLA) and L2 Bundle Member attributes are also
modeled. For BGP EPE links [RFC9086], the list
includes BGP peer SIDs (TLVs 1101-1103).¶
Prefix attributes
(bgp-ls-topo-prefix-attr): The prefix attribute list
covers IGP flags, route tags, extended route tags, prefix metric,
OSPF forwarding address, opaque prefix attributes, prefix-SIDs
(TLV 1158) [RFC9085] with label or index values
and algorithm, and SRv6 Locator attributes
[RFC9514].¶
SRv6 SID attributes
(bgp-ls-topo-srv6-sid-attr): SRv6 SID entries carry the
SRv6 endpoint behavior (TLV 1250) and the SRv6 SID structure
sub-TLV (TLV 1252), which encodes the locator block length,
locator node length, function length, and argument length fields
[RFC9514].¶

<CODE ENDS>
The ietf-bgp-ls-topo-ospf submodule defines three
groupings that capture the OSPF-specific NLRI descriptor fields
shared between OSPFv2 and OSPFv3:
bgp-ls-ospf-node-common (for node NLRIs),
bgp-ls-ospf-link-common (for link NLRIs), and
bgp-ls-ospf-prefix-common (for prefix NLRIs). Each
grouping includes the is-as-scoped leaf and the
area-id leaf. When is-as-scoped is true, the
NLRI is scoped to the entire AS and the area-id is not
applicable; when false, the area-id identifies the OSPF
area to which the NLRI belongs. The route-type leaf in
bgp-ls-ospf-prefix-common distinguishes intra-area,
inter-area, external Type 1, external Type 2, NSSA Type 1, and
NSSA Type 2 routes, as defined in Section 5.2.3.2 of
[RFC9552].¶
These groupings are used by the ietf-bgp-lsdb module
for all four OSPFv2/OSPFv3 list types (node, link, prefix, and
SRv6 SID), eliminating duplication and ensuring that the OSPF
descriptor fields are consistently defined across all NLRI
types.¶

This memo registers the following namespace URIs in the IETF XML Registry [RFC3688]:¶
This document registers the following YANG modules in the "YANG Module Names" registry [RFC6020]:¶
The YANG modules specified in this document define schemas for data that are 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 Network Configuration Access Control Model (NACM) [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.¶
The ietf-bgp-ls module augments the BGP configuration
model to add BGP-LS, BGP-LS-VPN, and BGP-LS-SPF address family
configuration. These configuration nodes are writable and could
be used to redirect topology information to unauthorized
collectors if modified without proper authorization. In
particular, unauthorized write access to the neighbor-level
BGP-LS configuration could cause the router to distribute its
LSDB contents to unintended recipients. These data nodes MUST be
protected by NACM access control policies limiting write access
to authorized administrators.¶
The ietf-bgp-lsdb module and its submodules contain
only config false (operational state) data nodes
representing the contents of the Link-State Database received from
the network. These nodes are readable but not writable. The
sensitive read-only data includes full network topology
information: node identifiers, link endpoints, prefix
advertisements, and SR/SRv6 label and SID assignments. An
unauthorized party with read access to this data could reconstruct
the network topology and identify traffic engineering paths, which
could facilitate traffic interception or denial-of-service attacks.
Access to these nodes SHOULD be restricted using NACM
[RFC8341] rules to authorized management
stations.¶
No RPC or action operations are defined in this document.¶
Here is a complete tree diagram for the configuration and operational part of the model.¶

The following examples illustrate the BGP-LS Link-State
Database (LSDB) populated with NLRIs from different source
protocols. The data shown represents the
bgp-ls-topology container defined in
ietf-bgp-lsdb, which is augmented into the
link-state presence container by
ietf-bgp-ls at the path

A BGP instance with one BGP-LS link (AS 65001
router-id 192.0.2.1 to AS 65002 router-id
192.0.2.2). The link carries a BGP Peer
Adjacency SID attribute (bgp-peer-sids)
as defined in ietf-bgp-ls-topo-attr,
demonstrating the new topology attribute
submodule. The BGP protocol does not define
node or prefix NLRIs in this model.¶
