1. Description
[I-D.ietf-rift-rift] specifies a topology information element (TIE)
that can carry unstructured key value pairs of data. This document
defines a registry for the keys to allow for vendor specific values
being carried without risking a collision with future standardized
values.
This document specifies also several well-known keys and their values
including a registry to allow for easier interoperability between
implementations.
2. Key Type Registry
The first octet of every key is a value from a "RIFT Key Types
Registry" which may specify the according key structure further.
3. OUI Key Type
This section reserves a key type value to indicate a vendor specific
key with further indication via Organizationally Unique Identifier
(OUI) which organization the key belongs to. The value of that first
octet is TBD1. The structure of the key is indicated in the figure
Figure 1.

4. Well-Known Key Type
This section reserves a key type value in Key Type Registry to
indicate a well-known key that all implementations SHOULD support.
The type is followed by a 3 octets value from a "RIFT Well-Known Key"
Registry describing the structure of the value it carries. The
resulting structure of the key is provided in Figure 2.

5. IANA Considerations
This section requests registries that help govern RIFT key values via
usual IANA registry procedures. All values not suggested as to be
considered available for assignment. Allocation of new values is
always performed via `Expert Review` action.
5.1. Key Type Registry
This is registry for key types for keys contained in RIFT KV TIEs.
The range of values is 0 .. 255
5.1.1. Requested Entries
Name Value Description
OUI TBD1 Followed by 3 octets of OUI.
Well-Known TBD2 Followed by 3 octets value from Well-Known Key
Key Type Registry.

5.2. Well-Known Key Type Registry
This is registry for key types for well-known keys contained in RIFT
KV TIEs. The range of values is 0 .. 2^24-1
5.2.1. Requested Entries
Name Value Description
Illegal 0 Not allowed.
MAC/IP Binding TBD2 To be defined.
FAM Security Roll-Over Key TBD2 To be defined.
6. Security Considerations
This document introduces no new security concerns to RIFT or other
specifications referenced in this document given that key value pairs
are carried in TIEs that are already extensively secured by RIFT
specification itself.
7. Acknowledgements
To be provided.
