When using 0SPFv3 for an IPv4 environment, which statement is correct?
OSPFv3 supports both IPv4 and IPv6, but it requires IPv6 to be configured on the interfaces. This means that for OSPFv3 to be used in an IPv4 environment, the interfaces need to have the IPv6 address family (inet6) defined. Without this, OSPFv3 will not function correctly for IPv4.
if you want to use OSPFv3 for IPv4 routing, you would typically configure the family inet6 option along with the family inet option to enable OSPFv3 to handle both IPv6 and IPv4 routing.
OSPF must require IPv6 on interface

D is correct i tested in lab and OSPFv3 realm-ipv4-unicast neighborship is not coming up if the interface does not have family inet6 configured
