SYNOPSIS

11       ip [ OPTIONS ] fou  { COMMAND | help }

DESCRIPTION

18       The ip fou commands are used to create and delete receive ports for
19       Foo-over-UDP (FOU) as well as Generic UDP Encapsulation (GUE).
20
21       Foo-over-UDP allows encapsulating packets of an IP protocol directly
22       over UDP. The receiver infers the protocol of a packet received on a
23       FOU UDP port to be the protocol configured for the port.
24
25       Generic UDP Encapsulation (GUE) encapsulates packets of an IP protocol
26       within UDP and an encapsulation header. The encapsulation header con‐
27       tains the IP protocol number for the encapsulated packet.
28
29       When creating a FOU or GUE receive port, the port number is specified
30       in PORT argument. If FOU is used, the IP protocol number associated
31       with the port is specified in PROTO argument.
32
33       A FOU or GUE receive port is deleted by specifying PORT in the delete
34       command.

EXAMPLES

37   Configure a FOU receive port for GRE bound to 7777
38       # ip fou add port 7777 ipproto 47
39
40   Configure a FOU receive port for IPIP bound to 8888
41       # ip fou add port 8888 ipproto 4
42
43   Configure a GUE receive port bound to 9999
44       # ip fou add port 9999 gue
45
46   Delete the GUE receive port bound to 9999
47       # ip fou del port 9999
