BGP default-originate

I have a question regarding BGP's default-originate command.

Say for example in RouterA, i set

-- neighbor 172.16.20.1 default-originate

By doing the 'default-originate', you are having routerA send a route

0.0.0.0/0 via BGP out to RouterB.

This is useful in many cases where a customer doesn't really want to do a full BGP feed, but are only doing BGP to do multi-homed connectivity, and just want a default-route out via BGP to figure out which service provider to use.

RouterB could filter it the announcement, or do whatever it wants to with the routes as received. It doesn't have to listen to the 0.0.0.0/0 announcement.
