What is one feature that OSPFv3 supports that OSPFv2 does not?

OSPFv3 introduces the capability to support multiple instances of OSPF, which allows for greater flexibility in managing network topologies. This means that different OSPF routing domains can coexist within the same router, enabling better segmentation of routing information and more efficient use of resources. This feature is particularly beneficial in complex network architectures, such as those found in service provider environments or large enterprise networks, where different routing policies or configurations are required for distinct areas of the network.

On the other hand, OSPFv2 does not inherently support multiple instances. Instead, it operates as a single instance per router/interface, which can lead to limitations in scalability and flexibility when managing multiple separate routing requirements.

The other options offered do not accurately characterize enhancements specific to OSPFv3 compared to OSPFv2. While enhanced security is a consideration in OSPFv3, particularly with the incorporation of IPv6 security features, it's not as clear-cut as OSPFv3’s support for multiple instances, which is a distinctive and significant enhancement. Lower latency and static routing are concepts that relate more broadly to IP routing and do not represent unique features of OSPFv3 over OSPFv2.
