There are two ways

1) network0.0.0.0 mask0.0.0.0

This will advertise a default route to all of its peers and in order to advertise a default route

there should be a default route in the RIB.

2) neighbor default-originate

We can use this format to advertise routes selectively, and It is not required to have a matching default

route in the BGP table or the RIB
