Hi Aijun,

Thanks for the update. I have one note on this revised paragraph:

   The path established by this object MUST have higher priority than
   the other paths calculated by dynamic IGP protocol, and MUST have
   lower priority than the static route configured by manual or NETCONF
   or any other static means.

IMO MUST without any qualification is too strong here, because generally in my experience, routing implementations let the operator configure the sorting/priority order of different protocols. Would it be correct to add “by default” here, as in, 

NEW:
   By default, 
   the path established by this object MUST have higher priority than
   the other paths calculated by dynamic IGP protocol, and MUST have
   lower priority than the static route configured by manual or NETCONF
   or any other static means.

Thanks,

—John
