An engineer must interconnect customer data centers by using a 10-Gbps, unicast-only, Layer 3 circuit. The requirement is to stretch the Layer 2 connection over the tunnel, isolate STP traffic, and create more than two million logical network segments. Which solution meets these requirements?
The requirements include stretching the Layer 2 connection over a Layer 3 tunnel, isolating STP traffic, and supporting more than two million logical network segments. VXLAN EVPN is designed to stretch Layer 2 networks across geographically separated data centers over a Layer 3 infrastructure. It significantly exceeds the VLAN limit of 4096, supporting over 16 million segments. This makes VXLAN EVPN the most suitable solution that meets all specified requirements.
Answer: option C. - OTV: Limited scalability upto number of VLANS (4096). - VxLAN: 16 million + segments possible.
Agree, answer is C, VXLAN EVPN is designed for stretching Layer 2 connectivity across geographically separated data centers over Layer 3 networks like the one circuit mentioned.
