Is it ideal to be a stream entrant(Sotopanna) before you begin the practice of Anapanasati?

**Are there Pali Sutta teachings or other Buddhist teachings that suggest:** - Anapanasati is an ideal practice for non-stream entrants (beginners) and it can lead them to stream entry? - Attainment of stream entry is a prerequisite for Anapanasati's proper or 'ideal' practice? - Other practices are prescribed as an ideal path for attaining stream entry, separate from Anapanasati?" Also, I assume that Satipatthana is a form of Anapanasati, is that true?
