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

Hi Matthew and George,

Please find some comments/questions below.

-In Section 5.1 you have:

Src-Node_ID::Src-Tunnel_Num::Dst-Node_ID::Dst-Tunnel_Num

What is the reason of having a Dst-Tunnel_Num besides the Src-Tunnel_Num? 
Is it there to support associated unidirectional Tunnels/LSPs? If so it should be called out in the text. 

Same applies to the globally unique case.

-In Section 5.2 you simply append one LSP_Num to the above. This is a bit confusing to me, if there are Src/Dst Tunnel_Nums then two LSP_Nums would be needed too, wouldn't it?

-In Section 5.3 Mapping to GMPLS signaling does not use the Dst-Tunnel_Num. So this means that we may have two different tunnels identified with Src-Node_ID::Src-Tunnel_Num::Dst-Node_ID::Dst-Tunnel_Num. Is this intentional, e.g., the associated unidirectional case? This should be clarified.

Hmm, maybe the Dst-Tunnel_Num should be omitted altogether.

-Section 7 has a note saying to be aligned with the OAM fwk, is this still to be done?

-In section 7.1.2.1 there is a discussion on Tunnel MEG IDs.
How would Tunnel and LSP MEGs be used? What OAM would run at the Tunnel level and not at the LSP level?
Do we need Tunnel MEG_IDs as defined in 7.1.2.1?

-Section 7.1.2.2, the Dst-Tunnel_Num question applies here too.

-Section 8 talks about open issues? When will these be addressed?

Thanks,
Attila
