# # Layer Two Tunneling Protocol (L2TP) # menuconfig L2TP tristate "Layer Two Tunneling Protocol (L2TP)" depends on INET ---help--- Layer Two Tunneling Protocol From RFC 2661 . L2TP facilitates the tunneling of packets across an intervening network in a way that is as transparent as possible to both end-users and applications. L2TP is often used to tunnel PPP traffic over IP tunnels. One IP tunnel may carry thousands of individual PPP connections. L2TP is also used as a VPN protocol, popular with home workers to connect to their offices. The kernel component handles only L2TP data packets: a userland daemon handles L2TP the control protocol (tunnel and session setup). One such daemon is OpenL2TP (http://openl2tp.org/). If you don't need L2TP, say N. To compile all L2TP code as modules, choose M here.
