3. Start matching down, label by label, in the zone. The
matching process can terminate several ways:
You leave the zone when you hit the NS RRset at bottom of
zone. 3b reinforces this statement. Glue is below the
b. If a match would take us out of the authoritative data,
we have a referral. This happens when we encounter a
node with NS RRs marking cuts along the bottom of a
RFC 2181 also has a retriction about promoting additional
records (glue) to the answer section.
