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
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.
