[j-nsp] BGP advertise-inactive (even not the *best* BGP route)

[Paul Goyette]

Well, 


Whereas, BGP advertises a set of path attributes and a list
of prefixes to which that set of attributes applies, _and_ 

Whereas, BGP protocol spec says that if a prefix is later 
associated with a new set of path attributes then the new set 
replaces the old set,

How would you propose that we associate a single prefix with
more than one set of attributes?
