Hello,

Currently wireshark decodes netflow v9 type=128 as "SRC_AS_PEER" and
type=129 as "DST_AS_PEER". Does anyone know in which RFC or other
documents they are defined?

- from packet-netflow.c:
|static const value_string v9_template_types[] = {
|...
|    { 128, "SRC_AS_PEER" },
|    { 129, "DST_AS_PEER" },

In RFC5102 (for IPFIX) id=128 is defined as "bgpNextAdjacentAsNumber"
and id=129 as "bgpPrevAdjacentAsNumber". I think the former is equal to
"DST_AS_PEER" and the latter is equal to "SRC_AS_PEER".

I'd like to know whether this difference is a bug of wireshark or not.

Regards,
