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 original 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.
