RFC 8294
Common YANG Data Types for the Routing Area
RFC 8294: Common YANG Data Types for the Routing Area 🎀
Part 1 of 6, bestie 💖
This is RFC 8294, "Common YANG Data Types for the Routing Area" 🦋. It's a Standards Track document from the IETF, dated December 2017, with ISSN 2070-1721. The authors are X. Liu (Jabil), Y. Qu (Futurewei Technologies, Inc.), A. Lindem (Cisco Systems), C. Hopps (Deutsche Telekom), and L. Berger (LabN Consulting, L.L.C.) 👑.

YANG [RFC6020] [RFC7950] is the data modeling language we use to model configuration data, state data, Remote Procedure Calls, and notifications for network management protocols 🍓. It comes with a small set of built-in data types, and it gives you ways to derive new types from those built-ins, which is honestly the best part 🧚.
This document brings in a collection of common data types derived from YANG's built-in types. They're meant to be the go-to common types for modeling in the routing area 💅.
1.1. Terminology
The terminology for describing YANG data models is found in [RFC7950].
2. Overview 🦋
Okay so this document defines two YANG modules for common routing types: ietf-routing-types and iana-routing-types 👑. The only imports (ietf-yang-types and ietf-inet-types; see Section 3) come from [RFC6991]. The ietf-routing-types module holds the common routing types that don't map directly to IANA registries. Here's the lineup 💖:
router-id Router Identifiers are commonly used to identify nodes in routing and other control-plane protocols 🌈. You can see an example usage of router-id in [OSPF-YANG].
route-target Route Targets (RTs) are commonly used to control the distribution of Virtual Routing and Forwarding (VRF) information (see [RFC4364]) to support BGP/MPLS IP Virtual Private Networks (VPNs) and BGP/MPLS Ethernet VPNs [RFC7432] ✨. An example usage can be found in [L2VPN-YANG].
ipv6-route-target IPv6 Route Targets are similar to standard Route Targets, except that they're IPv6 Address Specific BGP Extended Communities, as described in [RFC5701] 😭. An IPv6 Route Target is 20 octets and includes an IPv6 address as the global administrator.
route-target-type This type defines the import and export rules of Route Targets, as described in Section 4.3.1 of [RFC4364] 🎀.
route-distinguisher Route Distinguishers (RDs) are commonly used to tell separate routes apart in support of VPNs 🔥. For example, as described in [RFC4364], RDs are commonly used to identify independent VPNs and VRFs, and, more generally, to identify multiple routes to the same prefix. Iconic 👑.
route-origin A Route Origin is commonly used to indicate the Site of Origin for VRF information (see [RFC4364]) to support BGP/MPLS IP VPNs and BGP/MPLS Ethernet VPNs [RFC7432] 💜.
ipv6-route-origin An IPv6 Route Origin would also be used to indicate the Site of Origin for VRF information (see [RFC4364]) to support VPNs 🧚. IPv6 Route Origins are IPv6 Address Specific BGP Extended Communities, as described in [RFC5701]. An IPv6 Route Origin is 20 octets and includes an IPv6 address as the global administrator.
ipv4-multicast-group-address This type defines the representation of an IPv4 multicast group address, which lives in the range of 224.0.0.0 to 239.255.255.255 🦋. An example usage can be found in [PIM-YANG].
ipv6-multicast-group-address This type defines the representation of an IPv6 multicast group address, which lives in the range of ff00::/8 🌸. An example usage can be found in [PIM-YANG].
ip-multicast-group-address This type represents an IP multicast group address and is IP version neutral. The format of the textual representation implies the IP version 🫶. An example usage can be found in [PIM-YANG].
ipv4-multicast-source-address This represents the IPv4 source address type for use in multicast control protocols. It also lets you indicate wildcard sources, i.e., "*" 🙈. An example of where this type may/will be used is [PIM-YANG].
ipv6-multicast-source-address This represents the IPv6 source address type for use in multicast control protocols. It also lets you indicate wildcard sources, i.e., "*" 💅. An example of where this type may/will be used is [PIM-YANG].
bandwidth-ieee-float32 This represents bandwidth in IEEE 754 floating-point 32-bit binary format [IEEE754] 🔥. It's commonly used in Traffic Engineering control-plane protocols. An example of where this type may/will be used is [OSPF-YANG].
link-access-type This type identifies the IGP link type 🍓.
timer-multiplier This type is used together with a timer-value type. It's generally used to indicate the number of timer-value intervals that may expire before a specific event has to happen 🌈. Examples include the arrival of any Bidirectional Forwarding Detection (BFD) packets (see [RFC5880] Section 6.8.4) or hello_interval [RFC3209].
timer-value-seconds16 This type covers timers that can be set in seconds, not set, or set to infinity 🧚. It supports a range of values that can be represented in a uint16 (2 octets).
timer-value-seconds32 This type covers timers that can be set in seconds, not set, or set to infinity ✨. It supports a range of values that can be represented in a uint32 (4 octets).
timer-value-milliseconds This type covers timers that can be set in milliseconds, not set, or set to infinity 👑. It supports a range of values that can be represented in a uint32 (4 octets).
percentage This type defines a percentage with a range of 0-100% 💖. An example usage can be found in [BGP-Model].
timeticks64 This type is based on the timeticks type defined in [RFC6991] but with 64-bit precision 🦋. It represents the time in hundredths of a second between two epochs. An example usage can be found in [BGP-Model].
uint24 This type defines a 24-bit unsigned integer 🌸. An example usage can be found in [OSPF-YANG].
generalized-label This type represents a Generalized Label for Generalized Multiprotocol Label Switching (GMPLS) [RFC3471] 💜. The Generalized Label doesn't identify its own type, so you know it from context. An example usage can be found in [TE-YANG].
mpls-label-special-purpose This type represents the special-purpose MPLS label values [RFC7274] 🎀.
mpls-label-general-use The 20-bit label value in an MPLS label stack is specified in [RFC3032] 🔥. This label value doesn't include the encodings of Traffic Class and TTL (Time to Live). The label range this type specifies is for general use, with the special-purpose MPLS label values excluded.
mpls-label The 20-bit label value in an MPLS label stack is specified in [RFC3032] 🫶. This label value doesn't include the encodings of Traffic Class and TTL. The label range this type covers includes both the general-use values and the special-purpose label values 🌈. An example usage can be found in [MPLS-Base-YANG].
This document also defines the following YANG groupings 🧚:
mpls-label-stack This grouping defines a reusable collection of schema nodes representing an MPLS label stack [RFC3032] ✨.
vpn-route-targets This grouping defines a reusable collection of schema nodes representing Route Target import-export rules used in BGP-enabled VPNs [RFC4364] [RFC4664] 👑. An example usage can be found in [L2VPN-YANG].
The iana-routing-types module holds the common routing types that do map directly to IANA mappings 💅. Here they are:
address-family This type defines values for use in Address Family identifiers 💖. The values are based on the IANA "Address Family Numbers" registry [IANA-ADDRESS-FAMILY-REGISTRY]. An example usage can be found in [BGP-Model].
subsequent-address-family This type defines values for use in Subsequent Address Family Identifiers (SAFIs) 🦋. The values are based on the IANA "Subsequent Address Family Identifiers (SAFI) Parameters" registry [IANA-SAFI-REGISTRY].

"A Route Target is an 8-octet BGP extended community
initially identifying a set of sites in a BGP VPN
(RFC 4364). However, it has since taken on a more general
role in BGP route filtering. A Route Target consists of two
or three fields: a 2-octet Type field, an administrator
field, and, optionally, an assigned number field.
According to the data formats for types 0, 1, 2, and 6 as
defined in RFC 4360, RFC 5668, and RFC 7432, the encoding
pattern is defined as:
0:2-octet-asn:4-octet-number
1:4-octet-ipv4addr:2-octet-number
2:4-octet-asn:2-octet-number
6:6-octet-mac-address
Additionally, a generic pattern is defined for future
Route Target types:
2-octet-other-hex-number:6-octet-hex-number
Some valid examples are 0:100:100, 1:1.1.1.1:100,
2:1234567890:203, and 6:26:00:08:92:78:00.";

}the route-target pattern is honestly a whole vibe, it's basically a regex with a dozen ORs and I respect the commitment 😭 the description says a Route Target is an 8-octet BGP extended community, and it was first about identifying sites in a BGP VPN, but now it's also used for route filtering more generally 🎀
the IPv6 version is the glow-up 🦋 it's a 20-octet BGP IPv6 Address Specific Extended Community, and the global administrator has to be an IPv6 address. there are two patterns for it, which is so extra and I'm here for it

"A Route Origin is an 8-octet BGP extended community
identifying the set of sites where the BGP route
originated (RFC 4364). A Route Origin will have the same
format as a Route Target as per RFC 4360 and will consist
of two or three fields: a 2-octet Type field, an
administrator field, and, optionally, an assigned number
field.
According to the data formats for types 0, 1, 2, and 6 as
defined in RFC 4360, RFC 5668, and RFC 7432, the encoding
pattern is defined as:
0:2-octet-asn:4-octet-number
1:4-octet-ipv4addr:2-octet-number
2:4-octet-asn:2-octet-number
6:6-octet-mac-address
Additionally, a generic pattern is defined for future
Route Origin types:
2-octet-other-hex-number:6-octet-hex-number
Some valid examples are 0:100:100, 1:1.1.1.1:100,
2:1234567890:203, and 6:26:00:08:92:78:00.";

<CODE ENDS>5. IANA Considerations 🎀
okay bestie, IANA is the registry keeper, so this section is all about what they need to add to their lists 📋✨ This document registers the following namespace URIs in the "IETF XML Registry" [RFC3688]:
URI: urn:ietf:params:xml:ns:yang:ietf-routing-types
Registrant Contact: The IESG.
XML: N/A; the requested URI is an XML namespace.
URI: urn:ietf:params:xml:ns:yang:iana-routing-types
Registrant Contact: IANA.
XML: N/A; the requested URI is an XML namespace.This document also registers the following YANG modules in the "YANG Module Names" registry [RFC6020] 💜
Name: ietf-routing-types
Namespace: urn:ietf:params:xml:ns:yang:ietf-routing-types
Prefix: rt-types
Reference: RFC 8294
Name: iana-routing-types
Namespace: urn:ietf:params:xml:ns:yang:iana-routing-types
Prefix: iana-rt-types
Reference: RFC 82945.1. IANA-Maintained iana-routing-types Module
this is the part where the IANA-maintained module gets its very first version 🌸 This document defines the initial version of the IANA-maintained iana-routing-types YANG module (Section 4).
The iana-routing-types YANG module is meant to reflect the "Address Family Numbers" registry [IANA-ADDRESS-FAMILY-REGISTRY] and the "Subsequent Address Family Identifiers (SAFI) Parameters" registry [IANA-SAFI-REGISTRY]. so it's basically a mirror of those two lists, and it's giving organized 🦋
IANA has added this note to the "iana-routing-types YANG Module" registry:
Address Families and Subsequent Address Families must not be
directly added to the iana-routing-types YANG module. They must
instead be respectively added to the "Address Family Numbers" and
"Subsequent Address Family Identifiers (SAFI) Parameters"
registries.so no sneaking entries straight into the module 🙅♀️ When an Address Family or Subsequent Address Family is respectively added to the "Address Family Numbers" registry or the "Subsequent Address Family Identifiers (SAFI) Parameters" registry, a new enum statement must be added to the iana-routing-types YANG module. The name of the enum is the same as the corresponding Address Family or SAFI, except that it will be a valid YANG identifier in all lowercase, with hyphens separating individual words in compound identifiers. The following enum statement, and substatements thereof, should be defined:
enum: Contains the YANG enum identifier for theaddress-family(for Address Families) orbgp-safi(for Subsequent Address Families). This may be the same as theaddress-familyorbgp-safi, or it may be a shorter version to facilitate YANG identifier usage.value: Contains the IANA-assigned value corresponding to theaddress-family(for Address Families) orbgp-safi(for Subsequent Address Families).status: Include only if a registration has been deprecated (use the valuedeprecated) or obsoleted (use the valueobsolete).description: Replicate the description from the registry, if any. Insert line breaks as needed so that the line does not exceed 72 characters.reference: Replicate the reference from the registry, if any, and add the title of the document.
Unassigned or reserved values are not present in these modules 🫧
When the iana-routing-types YANG module is updated, a new revision statement must be added in front of the existing revision statements. ✨
And IANA has added this new note to the "Address Family Numbers" and "Subsequent Address Family Identifiers (SAFI) Parameters" registries:
When this registry is modified, the YANG module iana-routing-types
must be updated as defined in RFC 8294.6. Security Considerations 💀
okay, security time, and I'm going to be dramatic about it 😭 This document defines common routing type definitions (i.e., typedef statements) using the YANG data modeling language. The definitions themselves have no security or privacy impact on the Internet, but the usage of these definitions in concrete YANG modules might have. The security considerations spelled out in the YANG 1.1 specification [RFC7950] apply for this document as well. so read those too, no skipping 🔥
