But you can learn a subset of addresses and still create your own
network/supernet. Hence "advertising" something or injecting them!
*shrug* Semantics. In normal environments to advertise a network where
reasonably one can assume we "own" the networks in question, the 'network'
command or redistribution are the ways to originate networks into the BGP
process...

But that still means that some one has to advertise them to you.
