[c-nsp] ES20, VPLS & netflow problem

[Dmitry Valdov]

Hello,

We have configuration with 2 ciscos 76xx/SUP720 connected together via
10Gb ports on ES20 (Ethernet Services) cards.
MPLS is there. Now we need to make VPLS vlan between them (for BGP full
table). We are exporting netflow information version 5 to the collector.
When traffic goes directly via 10G ports (routed) everything is OK, but 
if we reroute traffic via VPLS VLAN, there is no netflow information
exported about traffic entering the router via this vlan. Netflow 
information about every other traffic  (including traffic which enters 
throught normal SVI interfaces) is appears as usualy.

Is this bug or feature? Here is part of my configuration:
