Re: [mpls] mpls wg last call on draft-ietf-mpls-tp-identifiers-01

Hi,

Couple of comments:

1) Why the Interface_ID is 32-bit while the Tunnel_ID is 16-bit? Do we need to support more interfaces than tunnels? 
2) The draft defines the Global_Tunnel_ID as:
      Src-Global_ID::Src-Node_ID::Src-Tunnel_Num:: Dst-Global_ID::Dst-Node_ID::Dst-Tunnel_Num

This seems to define a bidirectional tunnel. Is that the intent? If so please clarify. If not then why Dst-Global_ID::Dst-Node_ID::Dst-Tunnel_Num is needed?

3) Is section 5.2 talking about unidirectional LSP or bidirectional LSP?
4) Section 7.1.2.1 says:
	Since a MEG pertains to a single MPLS-TP Tunnel, IP compatible MEG_IDs for MPLS-TP Tunnels are simply the corresponding Tunnel_IDs

Assuming the Tunnel_ID is a unidirectional ID, then this statement implies that for the reverse direction a different MEG_ID is required. Is that the intent? If so why?

5) Why are drafts part of the normative references?

6) Will section 8 (open issues) be removed before publishing? This section implies that the MEP and MIP definition is not yet aligned with framework?

Regards,
Shahram
