Detailed explanation-1: -OSPFv3 uses IPv6 link-local addresses to identify the OSPFv3 adjacency neighbors. The multicast addresses used by OSPFv3 are as follows: FF02::5-This address represents all SPF routers on the link-local scope; it is equivalent to 224.0. 0.5 in OSPFv2.

Detailed explanation-2: -Differences between OSPFv1 & OSPFv2 IP version: As discussed earlier, OSPFv2 supports IPv4 routed protocol whereas OSPFv3 supports the latest routed protocol version i.e. IPv6. OSPF Instances: OSPFv2 doesn’t support multiples OSPF instances per interface, whereas, OSPFv3 supports multiples OSPF instances per interface.

Detailed explanation-3: -Support for IPv6 addresses and prefixes. Ability to configure several IPv6 addresses on a device interface. (While OSPFv2 runs per IP subnet, OSPFv3 runs per link. Ability to run one instance of OSPFv2 and one instance of OSPFv3 concurrently on a link. Support for IPv6 link-state advertisements (LSAs).
