freebsd : how to allow loopback nexthop in OSPFv3-IPv4 ?

Hi all, I would like te to use the new feature "allow loopback nexthop in OSPFv3-IPv4 " on freebsd but I am not sure about the configuration. Let say 2 machines are linked to each others via a vlan. Should I pass the vlan as ptp or stub on freebsd ? Or is there any other way to have unnumbered interfaces on freebsd? Eg for the interface vlan330: protocol ospf v3 ospfv4 { ipv4 { import filter ospf_import; export filter ospf_export; }; area 0 { interface "lo1" { stub yes; }; interface "vlan330" { type ptp; cost 25; }; }; } Is this configuration correct?
