Route-map to advertise only default-routr

Is this the right route-map to only advertise default route to an ibgp neighbor ?

Appreciate any help

ip prefix-list DEFAULT_ONLY seq 5 permit 0.0.0.0/0

route-map OUT permit 10 match ip address prefix-list DEFAULT route-map OUT deny 20

router bgp 65002

address-family ipv4 neighbor x.x.x.x route-map out
