NetFlow on MPLS PE

Hi,

I have a customer requiring NetFlow data sent to them from the PE router. Is there a way to enable NetFlow only for a specific VRF?

Re: NetFlow on MPLS PE

The MPLS egress NetFlow accounting feature allows you to capture Internet Protocol (IP) flow information for packets undergoing MPLS label disposition; that is, packets that arrive on a router as MPLS and are transmitted as IP.

Re: NetFlow on MPLS PE

Hi Carlos,

Thanks a lot for the response. It is quite helpful. This doc describes a case in which NetFlow is sent to provider collector.

I want the NetFlow source interface and destination collector address are in the same VPN so that it can be sent to the customer collector. Otherwise, because of IP address space overlapping, it's quite complex to 'NAT' addresses to get to the customer destination via the backbone netowrk.

Thanks again.
