Doctor tempers ire at boundaries (10)

I believe the answer is:

perimeters

'boundaries' is the definition.
(perimeter is a kind of boundary)

'doctor tempers ire' is the wordplay.
'doctor' indicates anagramming the letters.
'tempers'+'ire'='tempersire'
'tempersire' anagrammed gives 'PERIMETERS'.

'at' acts as a link.

I've seen this clue in The Hindu.
