ip-fou - Foo-over-UDP receive port configuration
ip-gue - Generic UDP Encapsulation receive port configuration
ip fou add port PORT
ip fou del port PORT
The ip fou
commands are used to create and delete receive ports for
Foo-over-UDP (FOU) as well as Generic UDP Encapsulation (GUE).
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.
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.
When creating a FOU or GUE receive port, the port number is specified in
argument. If FOU is used, the IP protocol number associated with
the port is specified in PROTO
A FOU or GUE receive port is deleted by specifying PORT
in the delete
# ip fou add port 7777 ipproto 47
# ip fou add port 8888 ipproto 4
# ip fou add port 9999 gue
# ip fou del port 9999
