default origination is not conditioned on the presence of a default route in

route in the BGP routing table (it will not appear in the
command), nor does it install a default route in the Adj-RIB-Out for the
update group of peers so configured (it will not appear in the

Origination of the default route is not subject to a prefix filter configured
with the command
A route map may be configured to set attributes on the default route sent to
the neighbor. If the route map includes a match ip-address term, that term is
ignored. If the route map includes match community or match as-path
