Telemetry data from an MX router integrated with Corero (for DDoS detection and mitigation) appears inconsistent and unreliable. The telemetry stream does not deliver data smoothly, leading to monitoring gaps and visibility issues.

Telemetry data appears intermittent.

Data is not consistently sent or received between the MX router and Corero system.

Monitoring tools show missing or delayed telemetry updates.

When the payload size was configured to a larger value, it could exceed the path MTU limits of intermediate devices, resulting in packet fragmentation and suboptimal transmission.

 

As a result:

Solution

• Adjust the telemetry payload size on the MX router to a smaller value that fits within the network MTU.
• This prevents packet fragmentation during transmission.
