Which Junos configuration statement is used to enable OSPFv3 on an interface?

set protocols ospf3 interface ge-0/0/0 area 0

set protocols ospf area 0 interface ge-0/0/0

set protocols ipv6 ospf3 area 0 interface ge-0/0/0

set protocols ospf3 area 0 interface ge-0/0/0

An OSPFv3 adjacency between two Junos routers is flapping every few minutes. The engineer checks the logs and sees 'OSPFv3 neighbor down' messages. The interfaces are up, and the MTU is consistent. The engineer suspects IPsec authentication is misconfigured. Which configuration change would most likely resolve the issue?

Change the IPsec security association lifetime to a longer value

Disable IPsec and use simple password authentication instead

Verify that the IPsec security association is configured with the same SPI and key on both routers

Increase the OSPFv3 hello interval to reduce the frequency of authentication checks

Where is OSPFv3 route summarization typically configured?

On all routers in the backbone area

On Area Border Routers (ABRs) and Autonomous System Boundary Routers (ASBRs)

On the designated router (DR) of each network segment

On internal routers within an area

Which Junos command is used to verify OSPFv3 neighbors?

show routing protocol ospf3 neighbor

OSPFv3 JN0-650 Practice Questions (Page 2)

Part of the Interior Gateway Protocols (IGPs) domain, which makes up ~12% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~4–7 in this domain), expect 1–2 from this objective — we provide 23 practice questions to prepare you well beyond it.
