I think I see your point. How about: 

As specified in [RFC5340], OSPFv3 relies on IPsec [RFC4301] for 
authentication and confidentiality. [RFC 4552] specifies how IPsec is used
with OSPFv3 over IPv6 transport. In order to use OSPFv3 with IPv4
transport as specified herein, further work such as [ipsecospf] would
 be required. 

Thanks,
Acee
