[All JN0-363 Questions]

You want to share routes between two routing instances that you have configured?

What are two ways to accomplish this task? (Choose two.)

AUse a non-forwarding instance.

BConfigure an instance import policy

CCreate a forwarding instance.

DUse a RIB group.

Show Suggested Answer

Suggested Answer: B, D

static route with a next-hop of next-table pointing to the appropriate routing table which contains more accurate information rib-groups to mirror routing information from one route-table to another. However, in many cases, in order to make this work, interface-routes also need to be mirrored. RIB Group policy can be used to constrain the routing information instance-import and instance-export statements configured within the individual routing-instances to leak routes from one table to another. Again, policy can be used here to constrain the routing information. This method is more straightforward than the rib-group method A final approach is to use physical interfaces or logical-tunnels to stitch routing-instances and use a routing protocol or static routes across this connection between the two routing-instances.

To share routes between two routing instances on a Junos device, you can configure an instance import policy in one or both instances to import routes from the other instance. Alternatively, a RIB (Routing Information Base) group can be used to share routes between instances. Reference::

Wait, can you really use a non-forwarding instance? Sounds odd.

I’m not sure about that. Isn’t a forwarding instance more common?

You can definitely use a RIB group for that!

I think RIB groups were mentioned in a similar question, but I’m not confident if they’re the right answer here.

I feel like creating a forwarding instance could be related, but I can't recall if it actually helps with sharing routes.

I remember practicing with instance import policies; that seems like a solid choice for sharing routes between instances.

I think using a non-forwarding instance might be one way to share routes, but I'm not completely sure about the second option.

I'm not entirely sure about this one. I think options B and D are the correct answers, but I'm not 100% certain. I'll need to double-check my understanding of routing instances and how to share routes between them.

Okay, I've got this. The two ways to share routes are to configure an instance import policy (option B) and use a RIB group (option D). I'm confident I can explain those approaches in the exam.

Hmm, I'm a bit confused on the difference between a forwarding and non-forwarding instance. I'll need to review that concept before attempting this question.

This looks like a pretty straightforward question. I think the key is to understand the difference between forwarding and non-forwarding instances, and how instance import policies and RIB groups can be used to share routes.

Aha! I know this one. B and D are the correct answers. Configuring an instance import policy and using a RIB group are the way to go. Now, if only I could remember what a RIB group actually is...

I'm going with B and D too. Although, I have to admit, a non-forwarding instance sounds like something you'd use to avoid paying your internet bill. Just a little routing humor there!

B and D sound right to me. Using a non-forwarding instance doesn't make much sense, and I'm pretty sure a forwarding instance is for something else. Time to brush up on my routing instance knowledge!
