    Hi Sunil.

    In Junos, you configure an RSVP-signalled LSP using :
    set protocols mpls label-switched-path LSP1 to

    You must configure the egress of the LSP. CSPF will be run by default. You can disable CSPF by adding the no-cspf keyword.

    If you are trying to see the computed path (computed ERO).

    show mpls lsp ingress name <LSP NAME > extensive
    show mpls lsp egress name <LSP NAME > extensive

    Thanks for your response , but i'm not looking commands to show the lsp details or to configure the lsp . 

    below command in other vendors  will just run the cspf algorithm for particular destination and shows the output of computed hops without creating LSP.  same i'm looking in Junos. 

    Cisco : - show mpls traffic-eng topology path destination x.x.x.x
    Huawei:- display mpls te cspf destination x.x.x.x
    Nokia: - tools perform router mpls cspf to x.x.x.x
