MPLS Removes the need for core BGP tables ??

I am reading the new Cisco MPLS book and they state that you can use MPLS
to remove the need for you to have a full BGP mesh within your core routers
to achieve transit. Can someone please explain how this actually works
I have been racking my brains with no luck.

I can understand that you can use a tag pair for the next hop address
of your upstream peers instead of a tag pair for the actual route. But
this still doesnt explain how a remote pop will know network 123/8 is
reachable across the core via POP X.

Regards,
Kevin
