Question: What should happen to the 'M', 'P', and 'V' flag settings of re-used Diameter AVPs in the Gmb reference point, unless otherwise stated?
Option 1: They shall be reset to their default values.
Option 2: They shall maintain their original settings from the other existing Diameter Application.
Option 3: They shall be set according to the RADIUS VSA translation rules.
Option 4: They shall be ignored and not used in the Gmb reference point.
Explanation: According to the text, re-used AVPs shall maintain their 'M', 'P' and 'V' flag settings unless otherwise stated. This means that the flags should keep their original values from the other existing Diameter Application, ensuring consistency and avoiding potential conflicts or misinterpretations in the Gmb reference point.
