Hi Tony

Thanks for your kind explanation. It makes sense. It would be helpful if you 
could add these descriptions to the draft.

Hi Li,


Thanks for response, but I am still confused. For example, how the Sleeping 
Adjacencies TLV and Power-Sleep Capable Bit are used for path computation? 
Could you please provide an example?


Path computation cares about which links are sleeping.  If it cannot find a 
path with non-sleeping links, then it needs to think about which sleeping links 
should be awakened.

If an interface is not power sleep capable, then its PSP is not relevant in 
metric computation.

Regards,
Tony
