Hi everyone,
I have some old sites that need to have NetFlow V5 installed on some 2911 ISR's. The problem is that also are running router on a stick configuration! Yes, there are no L2/3 devices at this location. How can I put netflow on the interfaces and port it back to my location.... This site has three VLANs and the router has three interfaces. One of the interfaces is sending traffic back to my location.
EX:
int f0/0
ip address 192.168.1.0 255.255.255.0
int f0/0.11
ip address 10.120.130.0 255.255.255.0
encapsulation dot1Q 11
int f0/0.12
ip address 10.30.60.2 255.255.255.0
encapsulation dot1Q 12
where do I add the netflow information in order to send netflow back to my location. Which interface? the main or subinterface?
