Refer to the exhibit. After NetFlow was configured on the router, the collector stopped receiving flow information. Which action resolves the issue?

  • A Apply the ip flow egress command to the loopback2 interface.
  • B Modify the source through the ip flow-export source loopback1 command.
  • C Configure an IP address on the loopback2 interface to use as a source.
  • D Change the IP address of the loopback 2 interface to a public IP address.
Explanation

A NetFlow export source interface must have a configured IP address and be operational. Assigning an IP address to Loopback2 makes it a valid source for the UDP NetFlow export datagrams sent to the collector. Cisco IOS NetFlow Command Reference
