Mbh 13.48.2b

The son begotten by him upon her becomes a Sudra. A son that takes birth under circumstances other than those mentioned above, comes to be looked upon as a very inferior one. If a person of a lower order begets a son upon a woman of a superior order, such a son is regarded as outside the pale of the four pure orders. Indeed, such a son becomes on object of censure with the four principal orders. If a Kshatriya begets a son upon a Brahmana woman, such a son, without being included in any of the four pure orders, comes to be regarded as a Suta. The duties of a Suta are all connected with the reciting of eulogies and encomiums of kings and other great men. The son begotten by a Vaisya upon a woman of the Brahmana order comes to be regarded as a Vaidehaka. The duties assigned to him are the charge of bars and bolts for protecting the privacy of women of respectable households. Such sons have no cleansing rites laid down for them.[299] If a Sudra unites with a woman belonging to the foremost of the four orders, the son that is begotten is called a Chandala. Endued with a fierce disposition, he must live in the outskirts of cities and towns and the duty assigned to him is that of the public executioner. Such sons are always regarded as wretches of their race. These, O foremost of intelligent persons, are the offspring of intermixed orders. The son begotten by a Vaisya upon a Kshatriya woman becomes a Vandi or Magadha. The duties assigned to him are eloquent recitations of praise. The son begotten through transgression, by a Sudra upon a Kshatriya woman, becomes a Nishada and the duties assigned to him have reference to the catching of fish. If a Sudra happens to have intercourse with a Vaisya woman, the son begotten upon her comes to be called Ayogava. The duty assigned to such a person are those of a Takshan (carpenter). They that are Brahmanas should never accept gifts from such a person. They are not entitled to possess any kind of wealth.
