Hello,
the loopback will be advertised with whatever mask you give it. AFAIK, the
main reason why the loopback is usually given a 32-bit mask is that you
don4t want to waste address space, since the loopback is just a virtual
interface which is usually used for routing protocol purposes (especially
BGP and OSPF).
Here is a link to a document on the documentation CD:

Regards,
Georg
