set protocols bgp address-family ipv4-unicast route-map vpn export foo-map-out
set protocols bgp address-family ipv4-unicast route-map vpn import foo-map-in
set protocols bgp address-family ipv6-unicast route-map vpn export foo-map-out
set protocols bgp address-family ipv6-unicast route-map vpn import foo-map-in
