There are three nameservers for springer.de.  alpha.ntp.springer.de and
spm1.springer.de know that the em.springer.de subdomain is delegated to
spm1.springer.de and sdns.springer.de.  But the third nameserver,
deneb.dfn.de, doesn't know about the subdomain delegation, and it doesn't
have an entry for em08.em.springer.de.  So if your nameserver happened to
ask that server to look up link.springer.de, it will be told that it's a
CNAME pointing to a name that doesn't exist.

The springer.de administrator probably forgot to put a copy of the
subdomain's NS records in the parent domain, or forgot to update the serial
number of the parent domain when he did it.
