Hi Acee,


Thanks for your checking.



Yes, we have some early implementation experience in our network. 



This solution has been deployed on a small scale, covering the IS-IS and BGP-LS 
extensions. OSPF/OSPFv3 are not yet included at this stage.

We hope that once the document is finalized, this mechanism can be more widely 
adopted.



Best regard,

Liyan
