Hi Jia,

Label range is a SHOULD requirements and not MUST. The reason for Label Range is 
mainly for PHY chips that don't have large memory and can't store a lot of 
Labels. Otherwise the PTP LSP is setup via signaling that specifies the LSP as 
carrying 1588.

So the answer is that if a Label range is used it must be a Global range within 
a network and should not be used by any router for other applications.

Thanks,
Shahram

Hi Shahram,
 
One question about "PTP Label Range":
 
To my knowledge, label in MPLS network is a local  matter. For example, we may 
have per-interface or per-platform label space. Will  this specificed "PTP Label 
Range" conflict with the current in-use labels  for common LSPs? 

 
B.R.
Jia
