Hi Donatas, 
Got it. Those are not solving the same problem.
Best regards,

I was referring to https://datatracker.ietf.org/doc/html/draft-acee-idr-lldp-peer-discovery.

Hi Donatas, 
Thank you for your information.

I'm not sure if the existing work you mentioned refers to this draft: https://datatracker.ietf.org/doc/html/draft-filsfils-rtgwg-lightweight-host-routing-00. 
If I understand correctly, this draft addresses information advertising between the Server and Leaf switches.

draft-zhang-idr-portid-ec is different; it's used to advertise the interface between the Server and Leaf switches (via the Spine).
The purpose, as you stated, is to resolve last-hop congestion.

Cases where the Server and Leaf switches are not directly connected are not currently within the scope of this draft. 
If this solution were to be used, creating a tunnel between the Server and Leaf switches might be necessary.
Best regards,
Sandy

* We already have a draft for carrying LLDP information in BGP. Wouldn't that be better to continue the work?
* What happens if the server is not directly connected to the leaf? 
* I'm still concerned, what problem is trying to solve here? Congestion or what?

Hi, 
This draft tries to address the issue of requiring the advertising of the connection interface between Leaf switches and servers in some implementations when deploying BGP in data centers used for AI computing.
If you have experience in this deployment and implementation, or are interested in this topic, please feel free to provide suggestions and feedback. 
Thank you very much.
Best regards,
Sandy
