RE: RE : : Using DIAMETER_MISSING_AVP for optional AVP

Lionel,

I think the conclusion was "yes it is possible", and indeed it is.

If a server receives an AVP with M bit set that cannot recognize,
although the AVP is optional in the ABNF (i.e. in square brackets), the
Failed-AVP AVP is included in the failed answer.

Similarly, if the value of the AVP (which has the M bit set) is not
recognized the failed answer includes the Failed-AVP AVP.

Subject: RE : [AAA-WG]: Using DIAMETER_MISSING_AVP for optional AVP

Any other thought on this thread?
The initial question was:

"Based on the RFC 3588, is it possible to use the DIAMETER_MISSING_AVP
result code along with the Failed-AVP AVP to indicate that an optional
AVP (from the ABNF point of view) is missing in the received command? If
not, could you identify some operational issues?"
