indicates that the hop will be an outbound endpoint (OBEP). If neither bit is
set, the hop will be an intermediate participant. Both cannot be set at once.
Layer encryption type: 0 for AES (as in current tunnels);
1 for future (ChaCha?)
The request exipration is for future variable tunnel duration.
For now, the only supported value is 600 (10 minutes).
