US Patent 10574561 Centralized error telemetry using segment routing header tunneling

A network device receives a data packet including a source address and a destination address. The network device drops the data packet before it reaches the destination address and generates an error message indicating that the data packet has been dropped. The network device encapsulates the error message with a segment routing header comprising a list of segments. The first segment of the list of segments in the segment routing header identifies a remote server. The network device sends the encapsulated error message to the remote server based on the first segment of the segment routing header.
