A service provider operates a shared Ethernet segment between two different customers. The provider wants to run two separate OSPFv3 routing domains over the same physical link, each with its own adjacency and routing table. Which OSPFv3 feature allows this without using VLANs or separate physical interfaces?

Enable the 'multi-instance' flag in the OSPFv3 protocol configuration

Configure different area IDs for each OSPFv3 instance

Use different router IDs for each OSPFv3 instance

Configure different instance IDs on each OSPFv3 instance

Which statement correctly describes a key difference between OSPFv2 and OSPFv3?

OSPFv2 and OSPFv3 both use the same LSA flooding scope and the same authentication mechanisms.

OSPFv3 uses IPsec for authentication, while OSPFv2 uses a built-in authentication field in the OSPF header.

OSPFv2 supports IPv6 and IPv4, while OSPFv3 supports only IPv6.

OSPFv3 uses the same LSA types as OSPFv2, but with different names.

A network engineer is configuring OSPFv3 on a Junos router. The router has an interface with the link-local address fe80::1 and a global address 2001:db8:1::1. The engineer wants OSPFv3 to form an adjacency with a neighbor. Which address will be used as the source for OSPFv3 hello packets?
