Late reply, apologies, but I found the old case, and Netflow (At the time when opening the case) ended up being not supported, but on the "roadmap" as a supported feature...TAC could not give me any approx dates that it would be supported....Ill have to test out one of our 1001X's to see if its still the case.....it's certainly configurable under the BDI, just didnt "work" in one direction (But as I said, that was over a year ago)....

Kindly find the following document

Configuring Bridge Domain Interfaces - Cisco<http://www.cisco.com/c/en/us/td/docs/routers/asr1000/configuration/guide/chassis/asrswcfg/bdi.html>
Current Book Title. Cisco ASR 1000 Series Aggregation Services Routers Software Configuration Guide. Current Chapter Title. Configuring Bridge Domain Interfaces

Hmm..replied to this earlier, but didnt show up on the list (My other replies have come through immediately) - re-send....apologies for double post, if the original reply shows up :)

I ran into a similar problem on our older ASR1001's, trying to get FNF to work....one way traffic only being reported(Config was correct)....opened TAC case that was "protracted"....out of frustration, and needing FNF "immediately", I ended up having to just use old-style dot1Q subints, and FNF worked without issue(Same config as was on the BDI Int).....Ill dig up the old case details.....but this was at least a year ago....so was hoping the "bug" was fixed by now....

     I am playing to ntopng and nprobe to capture the flow exports from
a bridge domain interface, and I seem to only be seeing statistics for
one side of the conversation however (inbound internet -> hosts). The
BDI is connected to my default gateway and so certainly everything to
and from the internet has to pass by this way. I am running  03.10.05.S
on an asr1000, wondering if this is a bug/limitation/config error on my
