Does this do it?

ip as-path access-list 4 deny ^(1057_?)?(1057_?)?$
ip as-path access-list 4 per .*

Guys!!
Isn't there any unnecessary expression?
This router's AS number is 1057.
 
neighbor 1.2.3.4 filter-list 4 out
!
ip as-path access-list 4 deny ^$
ip as-path access-list 4 deny ^1057$
ip as-path access-list 4 deny ^1057_1057$
ip as-path access-list 4 permit .*
 
Thanks,
 
JP
