According to the spec, this is an 8byte array. Do you have further information
about
MPLS PAL RD in general, and how you would like this data to be printed? The
white
paper only refers to the tag as such whithout any details.
Furthermore it would be helpful if you could have me a small packet dump of your
netflow stream, big enough that it contains some templates and data records.
Are there any other users being interested in that? If so I can put it on the
todo stack. Currently I'm working on the IPFIX implementation.
