.SH DESCRIPTION
|
|
The
|
|
.B ip fou
|
|
commands are used to create and delete receive ports for Foo-over-UDP
|
|
(FOU) as well as Generic UDP Encapsulation (GUE).
|
|
.PP
|
|
Foo-over-UDP allows encapsulating packets of an IP protocol directly
|
|
over UDP. The receiver infers the protocol of a packet received on
|
|
a FOU UDP port to be the protocol configured for the port.
|
|
.PP
|
|
Generic UDP Encapsulation (GUE) encapsulates packets of an IP protocol
|
|
within UDP and an encapsulation header. The encapsulation header contains the
|
|
IP protocol number for the encapsulated packet.
|
|
.PP
|
|
When creating a FOU or GUE receive port, the port number is specified in
|
|
.I PORT
|
|
argument. If FOU is used, the IP protocol number associated with the port is specified in
|
|
.I PROTO
|
|
argument.
|
|
.PP
|
|
A FOU or GUE receive port is deleted by specifying
|
|
.I PORT
|
|
in the delete command.
