[All 350-601 Questions]

Refer to the exhibit.

A VXLAN data center fabric consists of three hosts mapped to different VLANs. Ingress VTEPs perform Layer 2 bridging and Layer 3 routing. Egress VTEPs only perform a Layer 2 bridging lookup. Which VNI values must be set to allow inter-VNI communication?

Show Suggested Answer Hide Answer
Suggested Answer: C

In a VXLAN data center fabric, inter-VNI communication requires mapping Layer 2 (L2) VLANs to their respective L2 VNIs and associating them with the correct Layer 3 (L3) VNI that corresponds to the VRF.In this case, VLAN 100 is mapped to L2 VNI 2020, and for inter-VNI routing to occur, it must be associated with an L3 VNI that corresponds to the VRF, which is Test_Telco_VRF to L3 VNI 1010.Reference: For more detailed information, you can refer to the Cisco Programmable Fabric with VXLAN BGP EVPN Configuration Guide1and the Data Center VXLAN EVPN guide

I feel like VLAN 100 should definitely map to a Layer 2 VNI, but I'm confused about the Layer 3 VNI part. Does it have to be the same for both VLANs?

I'm not entirely sure about this one. The VXLAN configuration seems complex, and I want to make sure I understand it correctly before selecting an answer. I'll review the question and exhibit again carefully.

Okay, I think I've got this. The key is that the ingress VTEPs need to have the same VNI values for Layer 2 and Layer 3 communication, while the egress VTEPs only need Layer 2 VNI values. I'll select the answer that matches that.

I'm leaning towards option C. The question specifically says the ingress VTEPs perform both Layer 2 and Layer 3, so we'd need a Layer 3 VNI in addition to the Layer 2 VNIs. The 'Test_Telco_VRF' VNI of 1010 seems like the right choice for the inter-VNI communication.

Hmm, I'm debating between options B and C. Option B seems to map the VLANs directly to the Layer 2 VNIs, which makes sense. But option C mentions a 'Test_Telco_VRF' which could be the Layer 3 component.

I think it's asking about the VNI values needed to allow inter-VNI communication in this VXLAN data center fabric. The exhibit shows three hosts mapped to different VLANs, with ingress VTEPs handling both Layer 2 and Layer 3, and egress VTEPs only doing Layer 2 bridging lookup.

Ah, I see what you mean. Okay, let me think this through. If the egress VTEPs only do Layer 2 bridging, then we need to use Layer 2 VNIs for inter-VNI communication, right?
