Refer to the exhibit. A network engineer must implement VXLAN between two core switches called CORE_2 and CORE_3. The core switches must have multicast disabled. In addition, the VLAN 100 called APP and VLAN 200 called DB must be extended between the core switches.
The initial VXLAN configuration has been completed on CORE_2. Which Network Virtual Interface configuration completes VXLAN configuration on the CORE_2 switch?


Correct Answer: A
To implement VXLAN (Virtual Extensible LAN) between CORE_2 and CORE_3 without multicast, we must use ingress replication, where VXLAN-encapsulated traffic is sent directly to specific peers instead of relying on multicast for distribution.
Key VXLAN Configuration Requirements:
1. Source Interface:
The loopback0 interface is used as the VTEP (VXLAN Tunnel Endpoint) source.
2. VNI (Virtual Network Identifier) Configuration:
- VLAN 100 (APP) is mapped to VNI 10100.
- VLAN 200 (DB) is mapped to VNI 10200.
3. Ingress Replication Protocol:
- Instead of multicast, ingress replication is used with static peer IPs.
- The peer IP (10.10.10.3) is specified for VXLAN packet forwarding.
