**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**

**Configure DHCP server for VLAN 10,20,30 on Core\_SW**
