Lyndon covered the diversity issue and the fact that we are not doing 
path computation here, but I would like to add one more comment since 
I've got a similar question.  For LSP1 to be aware of the association, 
one can send a full PATH message with the added association object. this 
is neither a refresh message nor a new path setup message. all nodes 
will process that message and be aware of the new association object and 
hence LSP1 will from then on know about the association.
I hope this helps
Richard.
