What is a correct use-case scenario for ZTP in Enterprise SONiC?
ZTP (Zero Touch Provisioning) is used to automate the configuration of switches, especially useful in scenarios where a failed unit needs to be replaced. By using ZTP, the switch can automatically download and apply the necessary configuration scripts upon boot-up, reducing the need for manual intervention and speeding up the deployment process.

What type of route is shown?
The exhibit shows a BGP EVPN route in a VXLAN environment. The route type can be determined based on the details provided. Type 2 routes in BGP EVPN are used to advertise MAC address reachability information between VTEPs (Virtual Tunnel End Points). The exhibit indicates a host route from another VTEP, which corresponds to a Type 2 route.

What is ECMP?
ECMP (Equal-Cost Multi-Path) is a Layer 3 routing feature that allows traffic to be forwarded using multiple available paths of equal cost. This improves bandwidth utilization and provides redundancy. ECMP is commonly used in modern networks to optimize the flow of traffic and increase the resiliency of network connections.

SIMULATION
Use the simulator to perform the following configuration task.
1. Map a single-tagged CVLAN 100 to SVLAN 200 translation on PE
switch interface Eth1/1.
2. Map a double-tagged VLAN packet with an outer CVLAN 100 and an
inner dot1q 200 to SVLAN 300 translation on PE switch interface
Eth1/2.
The necessary VLANs and VLAN stacking have already been configured.
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 Reference:
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.

These steps provide a comprehensive guide to configure VLAN translations on a Dell SONiC switch, ensuring that the specific requirements for single-tagged and double-tagged VLAN mappings are met.
Refer to the exhibit.
The route distinguisher was autogenerated. Which VLAN is mapped to VNI410?
The route distinguisher (RD) in the exhibit is 10.0.2.26:41. The RD typically reflects the VNI and VLAN mapping configuration. Given that the VNI is 410 and the RD ends with :41, it implies that VLAN 10 is mapped to VNI 410.
