| 9 | Layer Two Tunneling Protocol |
| 10 | |
| 11 | From RFC 2661 <http://www.ietf.org/rfc/rfc2661.txt>. |
| 12 | |
| 13 | L2TP facilitates the tunneling of packets across an |
| 14 | intervening network in a way that is as transparent as |
| 15 | possible to both end-users and applications. |
| 16 | |
| 17 | L2TP is often used to tunnel PPP traffic over IP |
| 18 | tunnels. One IP tunnel may carry thousands of individual PPP |
| 19 | connections. L2TP is also used as a VPN protocol, popular |
| 20 | with home workers to connect to their offices. |
| 21 | |
| 22 | The kernel component handles only L2TP data packets: a |
| 23 | userland daemon handles L2TP the control protocol (tunnel |
| 24 | and session setup). One such daemon is OpenL2TP |
| 25 | (http://openl2tp.org/). |
| 26 | |
| 27 | If you don't need L2TP, say N. To compile all L2TP code as |
| 28 | modules, choose M here. |
