In Spine and Leaf Design that involves the following:
• 8360 12-P 100G Spine Switches
• 8360 48-P 10G RJ45 Leaf Switches
• 100G SR4 Optical connections between Spine and Leafs Spine Switches = 8360 12-port 100G QSFP28 (F-B airflow)
Each Spine Switch uses:
• 1 x 100G QSFP28 SR4 Optic to each Leaf switch
Each Leaf Switch uses:
• 1 x 100G QSFP28 SR4 Optic to each Spine switch
• 2 x 100G 1M DAC for ISL
• 1 x 10G RJ45 for Keepalive
Each Spine switch has 4 available 100G QSFP28 interfaces.

You are setting up a single EVPN VXLAN fabric for a data center. A customer has one ESXi cluster in racks 1-3 that uses VLAN 10 for VMs in subnet 10.1.10.0/24. The customer has another ESXi cluster in racks 4-6 that uses VLAN 10 for VMs in subnet 10.2.10.0/24.
Which is correct?
- A . You can map VLAN 10 to different VNIs on the same switches if you place VLAN 10 in multiple VRFs
- B . You must tell the customer to change the VLAN ID in racks 4-6 to a unique ID
- C . You can use subnets rather than VLANs for VNI mappings so you can use the same configuration everywhere
- D . You can map VLAN 10 to one VNI on switches in racks 1-3 and to a different VNI on switches in racks 4-6
