Juniper Exam JN0-664 Topic 6 Question 32 Discussion

Actual exam question for Juniper's JN0-664 exam

Question #: 32
Topic #: 6

Exhibit

You want Site 1 to access three VLANs that are located in Site 2 and Site 3 The customer-facing interface on the PE-1 router is configured for Ethernet-VLAN encapsulation.

What is the minimum number of L2VPN routing instances to be configured to accomplish this task?

Show Suggested Answer

Suggested Answer: B

To allow Site 1 to access three VLANs that are located in Site 2 and Site 3, you need to configure three L2VPN routing instances on PE-1, one for each VLAN. Each L2VPN routing instance will have a different VLAN ID and a different VNI for VXLAN encapsulation. Each L2VPN routing instance will also have a different vrf-target export value to identify which VPN routes belong to which VLAN. This way, PE-1 can forward traffic from Site 1 to Site 2 and Site 3 based on the VLAN tags and VNIs.

C'mon, this is too easy. I bet the real challenge is figuring out which router has the best coffee machine in the break room. That's the real exam question we should be discussing!

Haha, I agree! The coffee machine is definitely the most important factor in choosing a router.

You're right, I didn't consider that. So maybe the answer is D) 6 to account for all the VLANs.

That makes sense, but wouldn't we need separate instances for each VLAN within the sites as well?

I agree with Tequila. The question states that Site 1 needs to access three VLANs, so the minimum number of L2VPN routing instances would be 2, one for each VLAN.
