ko thuLAB Diagram
Configure the topology as per the diagram
Configure VLAN_10 VLAN_20 VLAN_30 on Core_SW
Configure 802.1Q Trunk Link Between Access Switches and Core_SW
Configure VTP version 2 on Core_SW
Configure VTP domain name lab.com
Make sure rest of the switches will get this information
Configure the ports into their VLAN as per the topology
Configure the IP address to VLANs for inter VLAN routing
IP 10.10.10.0/24 to VLAN 10
IP 20.20.20.0/24 to VLAN 20
IP 30.30.30.0/24 to VLAN 30
