ME(4)		       FreeBSD Kernel Interfaces Manual			 ME(4)

NAME
     me	-- encapsulating network device

SYNOPSIS
     To	compile	the driver into	the kernel, place the following	line in	the
     kernel configuration file:

	   device me

     Alternatively, to load the	driver as a module at boot time, place the
     following line in loader.conf(5):

	   if_me_load="YES"

DESCRIPTION
     The me network interface pseudo device encapsulates datagrams into	IP.
     These encapsulated	datagrams are routed to	a destination host, where they
     are decapsulated and further routed to their final	destination.

     me	interfaces are dynamically created and destroyed with the ifconfig(8)
     create and	destroy	subcommands.

     This driver corresponds to	RFC 2004.  Datagrams are encapsulated into IP
     with a shorter encapsulation.  The	original IP header is modified and the
     modifications are inserted	between	the so modified	header and the origi-
     nal payload.  The protocol	number 55 is used for outer header.

NOTES
     For correct operation, the	me device needs	a route	to the decapsulating
     host that does not	run over the tunnel, as	this would be a	loop.
