Hi Manoj, 

No, the use of suggested label in this case would NOT be correct, as the
suggested labels can be ignored/ overridden by the receiving node.

Hi ,

       In gmpls signaling extensionsions for RSVP-TE , ccamp architecture on

gmpls has described Label Set object usage

    only for the "optical" domain viz. for carrying wavelengths ( Section

9.9 draft-ietf-ccamp-gmpls-architecture-02.txt) .

       Do we require to send Label set(i.e. time slots) for TDM switching as

well . In what way it can be useful .

Dear Manoj,

Yes, label set object is also useful in TDM case. E.g., SONET poses an additional requirement that the two interfaces of a bidirectional LSP SHOULD traverse the exact same link with the same SUKLM values for the two directions.

 The label set object can be used to constrain the downstream label to the same as the upstream label.

Thanks
