Help with Netflow and IRB or other solution!!

Looking for help!

PC------Vlan10--\

                 \--Switch--Trunk--Router--S0/0---WAN--(R-S)--Netflow_collector

Server--Vlan20--/

We have user PCs and Servers that need to be in the same broadcast domain.

We also need Netflow to forward PC-Server communication traffic to our Netflow collector.

We have tried IRB to bridge the two vlans but the Netflow application doesn't see the PC-Server traffic.

The netflow application does see traffic passing through the router just not traffic passing from Vlan10 to/from Vlan20 via the BVI interface.

:

Anyone have ANY IDEAS?

Router config:

interface F0/0

no ip address

ip nbar protocol-discovery

ip flow ingress

ip flow egress

ip route-cache flow

load-interval 30

!

int F0/0.10

encapsulation dot1q 10

ip accounting output-packets

ip nbar protocol-discovery

ip flow ingress

ip flow egress

bridge-group 1

!

int F0/0.20

encapsulation dot1q 20

ip accounting output-packets

ip nbar protocl-discovery

ip flow ingress

ip flow egress

bridge-group 1

!

int bvi 1

ip add 192.168.1.1 255.255.255.0

ip accounting output-packets

ip nbar protocol-discovery

ip flow ingress

ip flow egress

!

ip flow-export version 9

ip flow-export destination <ip>

!

bridge irb

bridge 1 protocol ieee

bridge 1 route ip

Thanks for looking, turns out the Netflow application is failing to see the traffic on the BVI.

Solution: Update the Netflow application or switch to new Netflow vendor!!!

Tks
