VRF Name as the Source Interface in the NetFlow Cache
For traffic received for an MPLS VPN on an MPLS interface, the source interface for the traffic in the
NetFlow cache is listed as the VPN name, not the physical interface on which the traffic was received.
For example, traffic being received on FastEthernet0/0 on PE2 in
NetFlow cache is listed as the VPN name, not the physical interface on which the traffic was received.
For example, traffic being received on FastEthernet0/0 on PE2 in
will be displayed in the
NetFlow cache on the router as being received over VPN Red, not interface FastEthernet0/0.
How to Configure NDE for VRF Interfaces for an MPLS VPN
Perform this task to configure the NDE for VRF Interfaces feature on an MPLS VPN. This configuration
is appropriate for the router named PE1 in
is appropriate for the router named PE1 in
. Repeat this task on router PE2 but remember to
change the interface references to the appropriate interfaces for PE2.
Note
This task does not include the commands to configure open shortest path first (OSPF) and border
gateway protocol (BGP) that are required to activate the MPLS VPN between routers PE1 and PE2. See
the
gateway protocol (BGP) that are required to activate the MPLS VPN between routers PE1 and PE2. See

configurations for all of the devices in the example network in
