Yakout,
Maybe someone will correct me if I'm wrong, but I believe that anytime
you form the aggregate by using the "aggregate-address" command it will
show an origin of i (internal) even on an EBGP peer.

Right.
Origin External or Internal depends on where you are originating the
aggregate, if you originate the aggregate from an IBGP neigbor then the
agg
will have origin (i), if you originate the agg from an EBGP neighbor the
origin will have () which means External.

Vincent,
The aggregate address by default removes the AS path information, the
as-set
option allows the agregate address to be advertised retaining the AS
Path
information, as for whether it is External or internal depends on where
you
advertise the aggregate to.

Hi,
When you configure the aggregate-address x.x.x.x x.x.x.x, you have
option of "as-set". What I want to know is, what "as-set" gives to the
aggregate route? as path only, or something else too?
Does aggregate route has attribute of "internal" or "external"?
If all specific routes are IBGP routes, is it mean that the aggregate
route is IBGP route too? or If EBGP ,....?
Thanks, V
