What is a key difference between OSPFv2 and OSPFv3?

OSPFv3 runs directly over IPv6 and does not require IPv4 addresses on interfaces

OSPFv3 uses a different SPF algorithm

OSPFv3 uses a different Router ID format

OSPFv3 does not support multiple areas

An engineer is configuring OSPF on a router that has multiple loopback interfaces and physical interfaces with IP addresses. The engineer wants to ensure that the OSPF Router ID is predictable and stable. Which configuration approach guarantees the Router ID is the highest loopback address?

Assign the highest IP address to a loopback interface and enable OSPF on that loopback.

Configure the OSPF Router ID manually with the 'set protocols ospf router-id' command.

Ensure the loopback interface is the only interface with an IP address in the router.

Use the 'set protocols ospf area 0 interface lo0.0 passive' command.

Which OSPF router type is responsible for connecting the backbone area (Area 0) to other OSPF areas?

Autonomous System Boundary Router (ASBR)

An engineer is configuring OSPF on a router that has multiple loopback interfaces. The engineer wants to ensure that the Router ID is the address of loopback 0 (10.0.0.1) and not the highest loopback address. Which configuration should be applied?

Assign a higher IP address to loopback 0 than other loopbacks.

Set the Router ID manually to 10.0.0.1.

Enable OSPF on loopback 0 with a higher priority.

Make loopback 0 passive in OSPF.

Part of the OSPF domain, which makes up ~4% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~1–2 in this domain), expect 1–1 from this objective — we provide 29 practice questions to prepare you well beyond it.
