RE: Notify Message Doubt

["manoj juneja" <manojkumarjuneja@hotmail.com>]

Hi George,
           If this is the only reason then does this mean that Notify 
Message has a significance only after the primary LSP is established  and 
this message can't be used during the primary LSP estblishment/setup.

Regards,
manoj.
