L2TP uses UDP messages over IP networks for both tunnel maintenance and tunneled data. The payloads of encapsulated PPP frames can be encrypted or compressed (or both); however, L2TP clients do not negotiate the use of MPPE for L2TP connections. Encryption for L2TP connections is provided by IPSec Encapsulating Security Payload (ESP) in transport mode.
