    Hello friends. I recently have studying about CSPF. So, I love the logical functions of protocol. But, I still with some doubt about the top.

    What is the requirements need to CSPF work correctly? (Talking simple away).

     1 - Lookup to LSP Attributes (this I have understand)

    2 - Lookup to Link (Available bandwidth and Admin-group)

    So, what is the other constraints need to CSPF?

    The constraints will be selected by you during configuration of the lsp and are outlined in this list.

    The constraints that CSPF considers include:

    • LSP attributes

      • Administrative groups (that is, link color requirements)

      • Bandwidth requirements

      • Explicit route (strict or loose)

      • Hop limitations

      • Priority (setup and hold)

    • Link attributes

      • Administrative groups (that is, link colors assigned to the link)

      • Reservable bandwidth of the links (static bandwidth minus the currently reserved bandwidth)
