EMC D-SNC-DY-00 Exam With Confidence Using Practice Dumps

Here are the steps to create the VTEP and map the VNI to the VLAN:

Enter Configuration Mode:

SwitchA# configure terminal

Create VTEP Interface:

SwitchA(config)# interface vtep1

SwitchA(config-if-vtep1)# ip address 10.10.10.1/24

SwitchA(config-if-vtep1)# exit

Map VNI 400 to VLAN 40:

SwitchA(config)# vlan 40

SwitchA(config-vlan)# vn-segment 400

SwitchA(config-vlan)# exit

Enable ARP Neighbor Suppression:

SwitchA(config)# interface Vlan40

SwitchA(config-if-Vlan40)# ip address 192.168.40.254/24

SwitchA(config-if-Vlan40)# vxlan arp-suppression

SwitchA(config-if-Vlan40)# exit

Save Configuration:

SwitchA# write memory

Enter Configuration Mode:

Begin by entering the global configuration mode to make changes to the switch configuration.

Create VTEP Interface:

Enter the interface configuration mode for the VTEP interface named vtep1 using interface vtep1.

Assign the IP address 10.10.10.1/24 to the VTEP interface using the ip address command.

Exit the interface configuration mode.

Map VNI 400 to VLAN 40:

Enter the VLAN configuration mode for VLAN 40 using vlan 40.

Map the VNI 400 to VLAN 40 using the vn-segment 400 command.

Exit the VLAN configuration mode.

Enable ARP Neighbor Suppression:

Enter the interface configuration mode for VLAN 40 using interface Vlan40.

Assign the anycast IP address 192.168.40.254/24 to the VLAN interface using the ip address command.

Enable ARP neighbor suppression using the vxlan arp-suppression command.

Exit the interface configuration mode.

Save Configuration:

Save the configuration to ensure the changes persist after a reboot using the write memory command.

These steps provide a comprehensive guide to configure a VTEP and map the VNI to VLAN 40 on Switch A, ensuring the specific requirements for IP addressing and ARP neighbor suppression are met.

In a symmetric Integrated Routing and Bridging (IRB) overlay network, the Source Virtual Tunnel End Point (VTEP) and the Destination VTEP route unencapsulated user traffic. Symmetric IRB ensures that routing occurs at both the ingress and egress VTEPs, allowing for optimized traffic flow and efficient network operations.

VXLAN Configuration Guide

Here are the steps to configure the required VLAN translations on a Dell SONiC switch:

Map a Single-Tagged CVLAN 100 to SVLAN 200 on Interface Eth1/1:

sonic# configure terminal

sonic(config)# interface Ethernet1/1

sonic(config-if-Ethernet1/1)# switchport mode trunk

sonic(config-if-Ethernet1/1)# switchport vlan mapping 100 200

sonic(config-if-Ethernet1/1)# end

sonic# write memory

Map a Double-Tagged VLAN Packet with Outer CVLAN 100 and Inner dot1q 200 to SVLAN 300 on Interface Eth1/2:

sonic# configure terminal

sonic(config)# interface Ethernet1/2

sonic(config-if-Ethernet1/2)# switchport mode trunk

sonic(config-if-Ethernet1/2)# switchport vlan mapping 100 200 300

sonic(config-if-Ethernet1/2)# end

sonic# write memory

Comprehensive Detailed Step by Step Explanation with References:

Enter Configuration Mode:

Access the global configuration mode using the configure terminal command.

Configure Interface Eth1/1:

Enter interface configuration mode for Ethernet1/1 using the command interface Ethernet1/1.

Set the switchport mode to trunk with the command switchport mode trunk.

Configure the VLAN translation using the switchport vlan mapping 100 200 command, which maps CVLAN 100 to SVLAN 200.

Exit the interface configuration mode by typing end.

Save the configuration with write memory.

Configure Interface Eth1/2:

Enter interface configuration mode for Ethernet1/2 using the command interface Ethernet1/2.

Set the switchport mode to trunk with the command switchport mode trunk.

Configure the double-tagged VLAN translation using the switchport vlan mapping 100 200 300 command, which maps packets with outer CVLAN 100 and inner dot1q 200 to SVLAN 300.

Exit the interface configuration mode by typing end.

Save the configuration with write memory.
