         Hi,

>1) Do LDP Entities, set by means of LDP MIB, appear in LSR MIB? If so, how?
>In what objects?

         LDP Entities represent label ranges. If labels from a label range
is realized in the TFIB, then they will be found in the LSR MIB. You
can find this relationship by way of the mapping tables in the LDP MIB.

>2) Does every LDP Entity always requires the Label Range (Generic, ATM, or
>FR) to be set?

         One or the other.

>3) Are Label Range set by means of LDP MIB considered per-platform or
>per-interface?

         Depends on the interface type, but usually only one.

>4) Do Label Range set by means of LDP MIB appear also in the
>mplsInterfaceConfTable from LSR MIB?

         Yes, it should be reflected there as well. The LSR MIB really
just reflects what is configured.
