RE: BGP Passing Route's w/o the Network Command

While you can do "default-information originate" under router bgp it doesn't
advertise it unless you have the default in the table. You can do it as well
on a neighbor statement, and it does it no matter what. So the default can
be sent via the neighbor statement without any other requirements met.
