Subject: [mpls-tp] draft mpls-tp-fault-02

Dear all,
I have a question for clarification about the draft mpls-tp-fault-02:

There are a certain number of options that potentially do not apply in PTN networks that are more or less highlighted in the document.

e.g from par 2.1.1: "in a normal transport environment ...AIS messages with the LDI flag set should be treated the same  as any other AIS messages. In more general MPLS environments ...the LDI flag enable faster switch-over upon a failure...."
e.g. Is R-flag really needed in a PTN environment?
e.g. can the Refresh timer set to 1sec. simplify the implementation? It is the typical value used in transport applications.

My feeling is that this proposal well addresses the need of MPLS routers but it doesn't clearly highlight the MPLS-TP router behavior. Why don't rename it as "mpls-fault" (without -tp) and start, for example, a new document, based on the previous one, where to clearly describe the configuration and options an MPLS-TP router have to support excluding all options/configurations/behaviors that does not pertain to the transport world.

This will result in less complex implementations, greater interworking, cheaper equipment and OPEX...

Best regards,
Alessandro
