• Configuration scheme 266
• Cost of the port is 200000 266
• Here we configure two instances to meet the requirement as is shown below 266
• Instance 266
• It is required that traffic in vlan 101 vlan 103 and traffic in vlan 104 vlan 106 should be 266
• Map the vlans to different instances to ensure traffic can be transmitted along the respective 266
