This issue can resolved in two ways:
1. Change the IP address Orion is managing the device by to match the IP address the flow is coming from. In this case 192.168.2.1.
2. Change or enter the following command with the interface that contains the IP address Orion NPM is managing the device by " ip flow-export source "interface with IP address 192.168.1.1"
There are a few ways to solve this problem. If possible, configure your device to send from the same interfaces you are managing the device with. You can do this on most Cisco devices with the source command "flow-export source ... ".
If your device doesn't support this, then the easiest thing to do is to manage it from the other IP address. Simply add the node with that address in NPM (more than likely you will want to delete the other address so you don't have duplicate nodes).
i had to configure the source on all the routers with the ip flow-export source command. will the router export flows with the source address if the source interface goes down?
The router is able to reach the NTA as there are two links to NTA. Dynamic routing is configured.
