LS.
Remember where the filters are applied.
On the local bgp table. Now in a bgp table of a confederation member, the AS
path will have the confederation AS as its AS path, not the confederation
identifier (or remote AS), this is added when a route is distributed to the
EBGP neighbour.
So the AS-path filter ^$ or locally originated will not work, there are no
empty AS paths in the BGP table.

Thanks Cassidy,
command: ip as-path access-list 1 permit ^\(65078\)$ makes it work
command: ip as-path access-list 1 permit ^$ still does not work in my Lab,
some Bugs !? I'll check it sometime later in other IOS.
Does anyone have the same problem like this ?
Rgds,
Long
