What are two enhancements that OSPFv3 supports over OSPFv2? (Choose two.)
A.
It requires the use of ARP.
B.
It can support multiple IPv6 subnets on a single link.
C.
It supports up to 2 instances of OSPFv3 over a common link.
D.
It routes over links rather than over networks.
Explanation:
IPv6 uses the term “link” instead of “subnet” or “network” to define a medium used to communicate between nodes at the link layer. Multiple IP subnets can be assigned to a single link, and two nodes can communicate with each other even if they do not share a common IP subnet.
