I sent a query to the WG list and so far I have > not heard about a single one. I already write a basic support of RFC 4203 publish originaly in Quagga and now available in FRRouting. Link Local /Remote Identifier are decoded and it is quiet simple to add configuration at the interface level to advertise them.

For us, there is a simple solution: Just use Link Local / Remote Identifier TLVs with Remote Identifier set to 0 if it is unknown. There is no need to create one more TLVs parameters. From an operator point of view, it is already very hard to manage all existing TE parameters. Why adding extra TLVs when existing ones could be used ?
