Details

IPv6 link-local scope addresses are not globally routable and must not be configured in any DNS zone. Similar to RFC1918 addresses, if a link-local scope address is inserted into a zone provided to clients, most routers will not forward this traffic beyond the local subnet.

Solution

The SA should remove any link-local addresses and replace with appropriate Site-Local or Global scope addresses.
