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 Hide 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!

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.

Yes, I agree. Each VLAN would need its own L2VPN routing instance.

I disagree, I believe the answer is C) 2 because each site needs its own L2VPN routing instance.

Hmm, this seems straightforward. I think the answer is C) 2. We need one L2VPN routing instance for each VLAN that needs to be accessed from Site 1.

Yes, that's correct. One L2VPN routing instance per VLAN is needed for Site 1 to access VLANs in Site 2 and Site 3.
