The first config denies all routes originating in autonomous system 54
and permits everything else.
The second config permits them but denies everything else.

Hi!
Is there any difference in working between these two configs
router bgp 100
neighbor 20.1.1.254 route-map ABC out
ip as-path access-list 1 permit _54$
route-map ABC deny 10
match as-path 1
route-map ABC permit 20
OR
router bgp 100
neighbor 20.1.1.254 filter-list 1 out
ip as-path access-list 1 permit _54$
