I need understanding the lines below. For some reason the "ge" option in the prefix list is throwing me off. So far, I understand it as BGP will NOT advertise X.X.160.0 out. Is that correct?
ip prefix-list OUT seq 5 permit X.X.160.0/20 ge 21
route-map OUT deny 20
match ip address prefix-list OUT
route-map OUT permit 100
match as-path 2
Router bpp xxxx
neighbor x.x.x.x route-map OUT out
