Export of IPFIX & v9 records of sampled packets through the management interface and WAN ports belonging to the non-default VRF instance

We support export of IPFIX or version 9 records of inline active flow monitoring sampled packets to collectors reachable through:

• Interfaces belonging to the mgmt_junos VRF instance.
• WAN ports belonging to the non-default VRF instance.

We configure this feature using the routing-instance configuration statement at the [edit forwarding-options sampling instance name family type flow-server IP-address] hierarchy level. 

You must ensure that the collectors are reachable through the management interface. We support a maximum of four collectors for each type of VRF instance. We can configure collectors for both types of VRF instances in the same sampling configuration. However, the collectors reachable through the mgmt_junos VRF instance and the collectors reachable through the WAN ports cannot coexist under the same family, because you can specify only one source IP address per family. We can specify inet collectors, inet6 collectors, or a mix of the two types.
