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.

Here are the steps to configure the VRF and the static route:

Enter Configuration Mode:

sonic# configure terminal

Create VRF "VrfGreen":

sonic(config)# ip vrf VrfGreen

Configure the Static Route:

sonic(config)# ip route vrf VrfGreen 172.16.128.64/28 10.10.10.1 213

Save Configuration:

sonic# write memory

Comprehensive Detailed Step by Step Explanation with References:

Enter Configuration Mode:

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

Create VRF "VrfGreen":

Use the command ip vrf VrfGreen to create a new VRF named "VrfGreen". This command sets up a new VRF instance which will isolate the routing table for this VRF from the global routing table and other VRFs.

Configure the Static Route:

Use the command ip route vrf VrfGreen 172.16.128.64/28 10.10.10.1 213 to configure the static route.

ip route vrf VrfGreen specifies that the route should be added to the "VrfGreen" VRF.

172.16.128.64/28 is the destination network.

10.10.10.1 is the next-hop IP address.

213 is the administrative distance, which in this case is set to a non-default value to influence route preference.

Save Configuration:

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