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.
Correct : A
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

Configure a VRF called "VrfGreen" and the static route in it to network 172.16.128.64/28 through next-hop 10.10.10.1. Set an administrative distance of 213.
Correct : A
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 Reference:
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.
