^^^^^^^^^^^^^
I think you need to re-assess that. from man (5) bgpd.conf
announce (all|none|self|default-route)
If set to none, no UPDATE messages will be sent to the
neighbor.
If set to default-route, only the default route will be
announced
to the neighbor. If set to all, all generated UPDATE messages
will be sent to the neighbor. This is usually used for
transit
AS's and IBGP peers. The default value for EBGP peers is
self,
which limits the sent UPDATE messages to announcements of the
local AS. The default for IBGP peers is all.
Which, you need to have sth like:
network 0.0.0.0/0
