The one is way using route-map:

!
router bgp 65001
 ..
 neighbor IX peer-group
 ..
 !
 address-family ipv4 unicast
  ..
  neighbor IX route-map ix-export in
  neighbor IX route-map ix-export out
  ..
 exit-address-family
!

ip prefix-list default seq 5 permit 0.0.0.0/0
!
route-map ix-export permit 10
 match ip address prefix-list default
!
route-map ix-import deny 10
 match ip address prefix-list default
!

An another way:

address-family ipv4 unicast
  ..
  neighbor IX prefix-list BOGONS-le in
  neighbor IX prefix-list ACCEPT_ANY out
..
ip prefix-list ACCEPT_ANY seq 5 permit any
ip prefix-list BOGONS-le seq 5 permit 10.0.0.0/8 le 32
..
