Juniper JN0-664 Exam - Topic 6 Question 56 Discussion

Actual exam question for Juniper's JN0-664 exam

Question #: 56
Topic #: 6

After a recent power outage, your manager asks you to investigate ways to automatically reduce the impact caused by suboptimal routing in your OSPF and OSPFv3 network after devices reboot.

Which three configuration statements accomplish this task? (Choose three.)

Aset protocols ospf3 realm ipv4-unicast overload timeout 900

Bset protocols ospf overload

Cset protocols ospf overload timeout 900

Dset protocols ospf3 overload

Eset protocols ospf3 overload timeout 900

Show Suggested Answer

Suggested Answer: A, C, E

To reduce the impact of suboptimal routing in OSPF and OSPFv3 after devices reboot, you can use the overload feature to prevent a router from being used as a transit router for a specified period of time. This allows the router to stabilize its routing table before forwarding traffic for other routers. To enable the overload feature, you need to do the following:

For OSPF, configure the overload statement under [edit protocols ospf] hierarchy level. You can also specify a timeout value in seconds to indicate how long the router should remain in overload state after it boots up. For example, set protocols ospf overload timeout 900 means that the router will be in overload state for 15 minutes after it boots up.

For OSPFv3, configure the overload statement under [edit protocols ospf3] hierarchy level. You can also specify a realm (ipv4-unicast or ipv6-unicast) and a timeout value in seconds to indicate how long the router should remain in overload state after it boots up for each realm. For example, set protocols ospf3 realm ipv4-unicast overload timeout 900 means that the router will be in overload state for 15 minutes after it boots up for IPv4 unicast routing.

Wait, is E) really necessary? Sounds excessive.

I think B) is also essential for proper routing.

Wait, we're supposed to choose three? I was just going to pick one. Oh well, C, E, and maybe A for good measure.

Haha, power outages and routing issues. Gotta love network admin life! I'd say C and E are the winners here.

Ah, the age-old question of OSPF vs OSPFv3. I'll go with C and E - keep it simple, right?

Hmm, I think B and D are the way to go. Overloading OSPF and OSPFv3 separately seems more precise.

C and E look good, but I'm not sure about the timeout value. Shouldn't it be a bit longer?

I’m leaning towards A and E, but I can't recall if the timeout value is always set to 900 seconds in practice scenarios.

I’m a bit confused about the difference between OSPF and OSPFv3 in these options. I think I need to double-check which commands apply to which version.

I remember practicing a question about OSPF overload settings, and I feel like options B and D were mentioned in that context.

I think option C sounds familiar, but I'm not entirely sure if the timeout value is correct.

This question seems pretty straightforward. I think the key is to identify the correct combination of OSPF and OSPFv3 configuration statements to address the issue. I'll give it a shot.

I remember learning about the "overload" feature in OSPF, but I'm not sure how it works exactly. I'll need to refresh my memory on that.

A) and C) are definitely needed for OSPF.

Okay, the key here is to find the configuration statements that can automatically reduce the impact of suboptimal routing after devices reboot. I'll need to think through the OSPF and OSPFv3 features that could help with that.
