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.

Notes:

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.
