Hello

I know it is bad to assume things , but i will take it  that you have 
both server A1 and A2 transfer the results to the central nagios .

What you must remember and is clearly stated in the docs is that the 
definitions of the remote server has to also be on the central server - 
they do not however need to be a duplicate on the remote server , that 
being said , the Parnet/child relation ship can and should be defined on 
the central server  for the whole network , BB1-->A1 -> hosts . while on 
each remote host you define the parent/child for only the relevant hosts 
that the host is checking .
so if host A1 id down stream from BB1 - it is not defined on A1 , but on 
the central  server only  ( it is also a good idea to have active 
monitoring  of  BB1 on the central so it will be able to  show real 
time  UP/Unknown statuses  ).

Hope this helps.
