14. IANA Considerations

This section only discusses updates required in the existing IANA protocol registries to accommodate version 1 of this protocol. See [RFC6810] for IANA considerations from the original (version 0) protocol.

All existing entries in the IANA "rpki-rtr-pdu" registry remain valid for protocol version 0. All of the PDU types allowed in protocol version 0 are also allowed in protocol version 1, with the addition of the new Router Key PDU. To reduce the likelihood of confusion, the PDU number used by the Router Key PDU in protocol version 1 is hereby registered as reserved (and unused) in protocol version 0.

The policy for adding to the registry is RFC Required per [RFC8126]; the document must be either Standards Track or Experimental.

The "rpki-rtr-pdu" registry has been updated as follows:

Protocol   PDU
Version    Type  Description
--------   ----  ---------------
   0-1       0   Serial Notify
   0-1       1   Serial Query
   0-1       2   Reset Query
   0-1       3   Cache Response
   0-1       4   IPv4 Prefix
   0-1       6   IPv6 Prefix
   0-1       7   End of Data
   0-1       8   Cache Reset
    0        9   Reserved
    1        9   Router Key
   0-1      10   Error Report
   0-1     255   Reserved

All existing entries in the IANA "rpki-rtr-error" registry remain valid for all protocol versions. Protocol version 1 adds one new error code:

Error
Code    Description
-----   ---------------------------
    8   Unexpected Protocol Version
