Internet This document defines a human readable notation for Validated ASPA Payloads (VAP, see ID-aspa-profile) for use with RPKI tooling based on ABNF (RFC 5234).
Requirements notation 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 when, and only when, they appear in all capitals, as shown here.
Introduction This informational document defines a human readable ASPA notation for Validated ASPA Payloads (VAPs) . The main motivations for providing this notations style are: * This can help to create consistency between RPKI Relying Party software output, making it easier for operators to compare results. * This can be used by RPKI Certificate Authorities (CA) command line interfaces and/or configuration. E.g. allowing a CA to provide a listing of intended VAPs which can be easily compared to RP output. * This can be used for documentation. That said, this definition is informational. Implementations can choose to use their own notation styles instead of, or in addition to this.
ASPA Notation Definition This specification uses ABNF syntax specified in . " providers = provider-as *(provider-separator provider-as) provider-as = asn provider-separator = ", " asn = ["AS"] uint32 uint32 = %d0-4294967295 ]]>
customer-asid This field represents the customerASID defined in section 3.2 of
providers This field represents the providers defined in section 3.3 of . Note that the normative constraints which are defined in that section mean that following :
  • There must be at least one provider-as.
  • The customer-asid "asn" value must not appear in any provider-as.
  • The elements of providers must be ordered in ascending numerical order by the "asn" value of the provider-as field.
  • Each "asn" value for used for a provider-as must be unique.
provider-as This field represents a Provider AS as defined in section 3.3 of .
asn This field can optionally be prepended with the string "AS" followed by a decimal value of a 32 bit Autonomous System Number using the asplain presentation as specified in . Decimal values MUST be used, and values MUST be part of the range 0-4294967295.
