Vijay,

I don't understand where you've read that the entity Index is
optional. An index can never be optional, it has to have a legel
value (in this case 1..4294967295) and should be obtained from the
'mplsLdpEntityIndexNext' object as written in the mib.

Joan earlier replied to Anil on the subject some week agoe.
