OSPFv3 will act very similarly to OSPFv2 regarding functionality across NBMAs, OSPF network type defaults to nonbroadcast on interfaces or multipoint interfaces, this requires that oSPF be configured with a static unicast neighbor whose address would be its link-local address to create a neighbor shipt.
It still takes a minute or two for a neighborship to form across frame relay but the key is to always remember to include the ipv6 ospf neighbor command using the neighbors link local address to form an adjacency.
