– L2TP
L2TP is suitable for Layer-2 tunneling. Static tunnels are useful to establish network links across IP
networks when the tunnels are fixed. L2TP tunnels can carry data of more than one session. Each session is
identified by a session id and its parent tunnel's tunnel id. A tunnel must be created before a session can be
created in the tunnel.
