Section 2.2 says:
Consistent with OSPFv2 Cryptographic Authentication [RFC2328], both OSPFv3 header checksum calculation and verification are omitted when the OSPFv3 authentication mechanism described in this specification is used.
It should say:
Please see notes ===== OSPFv3 authentication mechanism provides capability to detect corruption of OSPFv3 packet, which is under non authenticated operation achieved using OSPFv3 header checksum [RFC 5340] and LLS data block checksum [RFC 5613]. In spirit of OSPFv2 Cryptographic Authentication [RFC2328], OSPFv3 header checksum and LLS Data Block Checksum calculation and verification are omitted when the OSPFv3 authentication mechanism described in this specification is used.
Readers should consult: draft-ietf-ospf-rfc6506bis for the
resolution of this Erratum
RFC does not specify how to work with LLS Data Block Checksum.
Errata suggests omit checksum calculation/verification in the
same way like for OSPFv3 header checksum.
