Hello Chetan,

Good idea.. 

Following are my comments/feedback.

1) The advantage of the "LSPID" is not clearly mentioned.

    I understand the need of LSPID as follows. Please correct
    me if I am wrong. 

    A tunnel interface, is treated as a point-to-point interface.
    The Link TLV proposed in [OSPF-TE] provides support to
    specify point-to-point interfaces. However if there are multiple
    point-to-point links (They can be virtual tunnels/circuits etc.,) 
    originating on the same physical interface and ending on 
    the same physical interface between two routers, the source
    IP address, destination IP address will not help distinguish
    the different links. In this case a link id, or LSPID is helpful.

    If am I am right, can it be added? or the actual intent.

2) How the LSPID helps in automated CSPF calculation is
    not clearly highlighted. (I think automated CSPF for 
    TE Paths is the final intent). 

3) Sections 4, 5 are missing. 

with best regards
mani

Thanks

A New Internet-Draft is available from the on-line Internet-Drafts
directories.

        Title           : Signalling LSPID's in OSPF TE
        Author(s)       : K. Chetan, K. Sunil
        Filename        : draft-chetan-lspid-ospf-00.txt
        Pages           : 5
        Date            : 21-Mar-02

This draft introduces new a sub TLV to OSPF TE extensions to signal
the LSPID (Label Switch Path ID) of an LSP (Label Switch Path).
This information can be used by any mechanism (normally constraint
based path calculation (CSPF) procedures) to calculate paths that
may contain LSPID's as one its Explict Route Objects.
