NAME
me —
encapsulating network device
SYNOPSIS
To compile the driver into the kernel, place the following line in the kernel configuration file:
device meAlternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
if_me_load="YES"
DESCRIPTION
Theme 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.
