The NetworkMessage flags used with the discovery probe messages shall use the following bit values.
- UADPFlags bits 5 and 6 shall be false, bits 4 and 7 shall be true
- ExtendedFlags1 bits 3, 5 and 6 shall be false, bits 4 and 7 shall be true
- ExtendedFlags2 bit 2 shall be true, all other bits shall be false
The setting of the flags ensures a known value for the first three bytes plus the PublisherId in the NetworkMessage on the Publisher as receiver. The actual security settings for the NetworkMessage are indicated by the SecurityHeader.
