This draft introduces new IPFIX Information Elements to export key data from 
the Bit Index Explicit Replication (BIER) header, enabling detailed visibility 
into BIER-encapsulated traffic. This allows operators to identify BIER packets, 
determine their path and egress nodes, and analyze forwarding behavior for 
enhanced monitoring and troubleshooting in networks utilizing BIER multicast.


Look forward to your feedback and suggestions.




Best Regards

Yisong
