Reject-to-Networks

Overview

• Shows the number of networks with at least one Reject-Message-To-Network message in the capture.
• Router responds with a Reject-Message-To-Network if it doesn’t like the packet.
• Fails if there is a Reject-Message-To-Network for one or more networks.

Why it fails

• Device is badly configured.
• Proprietary device is talking on the network.
• Router cannot reach the destination network.
• Non-standard BACnet information is being communicated.
• The router firmware was updated, but changes haven’t taken effect.

How to fix it

• Identify the reject reason.
• Identify the source device that is sending the message.
• Ensure the router in the source network and any routers in between the source and the destination network have the latest information.
• Reset the device.
