sflow datagram format diagram

Hi,

I was wondering if anyone had a 'simple, easy to read' diagram that
breaks
down the fields, length of each field, and position of each field
within a
sflow datagram? I am having trouble understanding this information from
the RFC and am trying to determine whether or not the sflow packets
being
sent from our Extreme BD6808 is including BGP/routing information.

I'm using sflowtool as my collector, but am noticing that the
routing/BGP fields
are reported as blank or not at all. I have captured some sFlow
packets using
tcpdump and am trying to see if the routing/BGP fields are in the
packets.

Any help is appreciated.

Thanks,

Lloyd
