Hi there,
I've started testing an NfSen/NfDump setup to get some more insight into
the traffic traversing our network. This might help us to do some traffic
engineering where possible. So far, I'm hugely impressed, great tool/combo.
Very flexible. I was just wondering though, is there any chance of Netflow
v9 element ID 90 (MPLS PAL RD) getting supported in NfDump/NfSen ?
Our Cisco equipment is capable of exporting this information.
We have some PE devices where we use MPLS VPNs and I am exporting flow
information from those PE devices.
The mentioned field is supposedly indicating the MPLS Route Distinguisher
typically found ISP networks using MPLS VPNs.
Using this, we could build filters to match routes belonging to a specific
VPN (or RD). If I understand correctly that is.
It seems as though this information is lost right now at the collector and
I have no way of "distinguishing" the customer routes from each other when
doing reporting/filtering/querying in NfSen.
