Busy Routers

Overview

• Devices and networks can be configured to send a Router-Busy-To-Network message based on certain thresholds.
• When that router is busy, it will send a Router-Busy-To-Network message to any networks trying to talk to it.
• When it is no longer busy, it will send a Router-Available-To-Network message, clearing the previously busy signal.
• The diagnostic check fails if one or more routers send out a Router-Busy-To-Network message.

Why it fails

• Too much broadcast or directed/unicast traffic.
• The amount depends on the specific vendor, hardware capabilities, and configuration.
• The router is servicing too many networks.
• The router is servicing other things (firmware, etc.)

How to fix it

• Look at how busy the network is, and which devices are sending the most traffic to it.
• If those devices are sending traffic as they should, look at the router.
• See if the router is chewing up its resources.
• See what it’s trying to service (events or other networks).
• Check if it’s trying to send data or trend log is too big.
