That link goes directly to the index, did you mean the chapter titled  
"Redistributing BGP into IGP", http://www.brocade.com/downloads/documents/html_product_manuals/NI_05500c_ROUTING/BGP4.03.12.html#1072486 ?

You didn't mention any IGP in your original mail, so either that isn't
it or you didn't describe the situation correctly; I'm assuming the
latter since you did mention synchronization, although not in a way
that made much sense.

Normally, BGP will pass on all routes, unless you have 
filter-list/distribute-list/prefix-filter/route-maps applied.  The
rest is standard BGP.

I can't envision a scenario where having synchronization enabled and 
then redistributing BGP into your IGP (RIP/OSPF/IS-IS) makes sense if 
BGP is your IGP, as you sort of claim to be the case for you.
