Section 7 says:
+------------------------------------------------+---------------+ | Registry | Code Point | +------------------------------------------------+---------------+ | BGP Outbound Route Filtering (ORF) Types | CP-ORF (65) | | Transitive Opaque Extended Community Sub-Types | CP-ORF (0x03) | +------------------------------------------------+---------------+
It should say:
+------------------------------------------------+---------------+ | Registry | Code Point | +------------------------------------------------+---------------+ | BGP Outbound Route Filtering (ORF) Types | CP-ORF (65) | | Transitive Opaque Extended Community Sub-Types | CP-ORF (0x03) | | Capability Codes | CP-ORF (72) | +------------------------------------------------+---------------+
Notes:
In the original text, we forgot to mention the value of the BGP capability code.
--VERIFIER NOTES--
RFC 5291 describes The Outbound Route Filter (ORF) Capability for BGP. According to RFC 5291, when two BGP speakers initiate a session between one another and they intend to exchange ORFs of any type, they must advertise the ORF capability. The ORF capability is registered with a value of 3 in the IANA BGP Capability Code Registry. The ORF capability also includes a list of ORF types that the BGP speaker can send and/or receive. IANA also maintains a BGP Outbound Route Filtering (ORF) Types registry.
RFC 7543 describes a new ORF type, called the Covering Prefix ORF (CP-ORF). RFC 7543 should conform to generic ORF procedures defined in RFC 5291. Specifically, when two BGP speakers initiate a session between one another and they intend to exchange CP-ORFs, they must advertise the ORF capability (value 3). The ORF capability must include CP-ORF (value 65) in the ORF type list.
