Implementing and Operating Cisco Data Center Core Technologies (DCCOR) — Question 151
An engineer must perform an initial configuration of VXLAN Tunnel End-Point functionality on the Cisco Nexus 9000 Series platform. All the necessary features are already enabled on the switch. Which configuration set must be used to accomplish this goal?
Answer options
- A. NX9K(config)# interface loopback0 NX9K(config-if)# ip address 10.10.10.11/32 NX9K(config)# interface VLAN10 NX9K(config-if)# ip unnumbered loopback0 NX9K(config)# interface nve1 NX9K(contig-if-nve)# source-interface loopback0
- B. NX9K(config)# interface loopback0 NX9K(config-if)# ip address 10.10.10.11/32 NX9K(config)# interface overlay0 NX9K(config-if-overlay)# source-interface loopback0 NX9K(config)# interface VLAN10 NX9K(contig-if-nve)# source-interface loopback0
- C. NX9K(config)# interface loopback0 NX9K(config-if)# ip address 10.10.10.11/32 NX9K(config)# interface tunnel1 NX9K(config-if)# tunnel source loopback0 NX9K(config)# interface ethernet1/1 NX9K(contig-if)# ip unnumbered loopback0
- D. NX9K(config)# interface loopback0 NX9K(config-if)# ip address 10.10.10.11/32 NX9K(config)# interface nve1 NX9K(config-if-nve)# source-interface loopback0 NX9K(config)# interface ethernet1/1 NX9K(contig-if)# ip unnumbered loopback0
Correct answer: D
Explanation
The correct answer, D, includes the necessary configuration for VXLAN Tunnel End-Point by setting up the NVE interface with the correct source interface. Option A incorrectly configures a VLAN interface rather than the NVE interface, while option B uses an overlay interface that is not applicable for VXLAN. Option C mentions a tunnel interface, which is not the standard approach for VXLAN configurations on the Nexus platform.
