; - query for 0ttl.example.com. IN A
|
|
; - answer from upstream is SERVFAIL; will be cached for NORR_TTL(5)
|
|
; - check that the client gets the SERVFAIL; also cached
|
|
; - query again right after the TTL expired
|
|
; - this time the server answers with a 0 TTL RRset
|
|
; - check that we get the correct answer
