Speaking as WG member: 

Hi Chenxi, 


Why would anyone want these precise P2P metric on a LAN? Since it is a shared 
media, these are impossible to guarantee (unless the it the LAN is scantily 
under-provisioned). 

Also, if you did want to do TE on a LAN, why not just model it as a P2MP 
network rather than having the replicating these metric for a LAN and having 
the between the unicast routing topology and the TE topology??? 

This proposal doesn’t seem to have much practical value.

Thanks,
Acee
